Cracking a Boiled Egg in the Boiler and Other Days You Wish You Could Take Back

It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.

It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).

To name a couple of minor “Faux Pas” (how do you pluralize that word? I don’t know), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.

The first two stories both involve the Electrical Supervisors of two different Power Plants.

Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps. This was a reoccurring problem that required a lot of man hours to repair. The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.

A Bottom Ash Overflow Sump Pump or BAOSP for Short

So, Tom Gibson decided that he was going to fill the motor and pump cavity with turbine oil. All electricians knew that oil used in turbines is an insulator so electrically it wouldn’t short anything out. But something in the back of your mind automatically says that this isn’t going to work. I remember helping to fill the motor up with oil in the Maintenance shop and hooking up some motor leads from the nearby Maintenance shop 480 volt switchgear. Needless to say, as soon as the pump was turned on, it tripped the breaker and oil began leaking from the cable grommet.

That’s when common sense tells you that the all the oil causes too much drag on the rotor which will cause a 480 motor to trip very quickly. After removing some of the oil and trying it again with a larger breaker and still having the same result Tom was satisfied that this just wasn’t going to work. The pump and motor was sent away to a nearby electric shop to be rewound and other ways were developed by the help of our top notch machinist genius Randy Dailey who came up with a positive air pressure way to keep water out of the Bottom Ash Overflow Sump Pump and motor (also known as the BAOSP). Not much harm done and Tom Gibson didn’t feel too bad for trying something that the rest of us sort of thought was mildly insane.

The next story was told to me by my dear friend Bob Kennedy when I was working at a Gas Powered Plant in Midwest City and he was my acting foreman. So I didn’t witness this myself. This one was a little more dangerous, but still thankfully, no one was hurt. Ellis Rooks, the Electrical Supervisor needed to bump test a 4200 Volt motor and wanted to do it in place. For some reason he was not able to use the existing cables, maybe because that was the reason the motor was offline. Because one of the cables had gone to ground.

So, he decided that since the motor only pulled 5 to 10 amps he could use #10 wire and string three of them (for the three phases of the motor) from the main High Voltage switchgear across the turbine room floor over to the motor. Now, most electricians know how many amps different size wires can generally handle. It goes like this: #14 – 15 amps, #12 – 20 amps, #10 – 30 amps, #8 – 50 amps and on down (smaller numbers mean bigger wires).

So, Ellis thought that since the motor only pulls around 5 amps, and he only wanted to bump the motor (that is, turn it on and off quickly) to watch it rotate, he thought that even though there was normally three 3 – 0 cables (pronounced three aught for 3 zeroes, very large wire) wired to the motor, this would be all right because he was only going to bump it.

This works when you are using is 120 or 220 volts

Needless to say, but I will anyway, when the motor was bumped, all that was left of the #10 wires were three black streaks of carbon across the turbine room floor where the wire used to exist before it immediately vaporized. You see, common sense tells you that 4200 volts times 5 amps = 21,000 watts of power. However, the starting amps on a motor like this may be around 50 to 100 amps, which would equal 210 to 420 Kilowatts of power (or about 1/5 to 2/5 of a Megawatt). Thus vaporizing the small size 10 wire that is used to wire your house.

All right. I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler. This happened when I was still a janitor but was loaned to the Labor Crew during outages. When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler.

Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must. Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected.

It wasn’t easy looking like a pole with no shoulders, but I tried my best. I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this.  This is the Reheater area of the boiler in the diagram below:

Before we could get into the boiler to start shaking tubes, the dynamiters would go in there first and blow up the bigger clinkers. So, for a couple of days some times, at the beginning of an overhaul, you would hear someone come over the PA system about every 20 minutes saying, “Stand Clear of Number One Boiler, We’re Gonna Blast!!!” This became so common to hear over the years that unless you were up on the boiler helping out, you didn’t pay any attention to it.

This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers. Maybe some Soot, I don’t know, but not Ash. Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul.  Reggie automatically reminded you of Richard Pryor.  He had even developed a “Richard Pryor” way of talking.

We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area. We brought our large toolbox and other equipment over to the motor. Andy Tubbs and Diana Brien were there with Reggie and I. I think Gary Wehunt was there with us also.

When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency. Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.

Anyway. That wasn’t the day that someone wished they could take back, but I thought I would throw that one in anyway so that now Reggie will wish that he could take back that day.

When I was on Labor Crew, and we were waiting on the boiler for the dynamiters to blast all the large clinkers, the engineer in charge, Ed Hutchins decided that things would go a lot quicker if all the laborers would go into the boiler and shake tubes while the dynamiters were setting their charges. Then we would climb out when they were ready to blast, and then go back in. So, we did that. All 10 or so of us climbed into the boiler, and went to work rattling boiler tubes until we heard someone yell, “Fire In The Hole!!!” Then we would all head for the one entrance and climb out and wait for the blast.

The extra time it took to get all of us in the boiler and back out again actually slowed everything down. We weren’t able to get much work done each time, and everyone spent most of their time climbing in and out instead of working, including the dynamiters. So Ed had another brilliant idea. What if we stayed in the boiler while the dynamite exploded? Then we wouldn’t be wasting valuable time climbing in and out and really wouldn’t have to stop working at all.

Of course, common sense was telling us that we didn’t want to be in an enclosed boiler while several sticks worth of dynamite all exploded nearby, so the engineer decided to prove to us how safe it was by standing just inside the entrance of the boiler with his ear plugs in his ears while the dynamite exploded. The dynamiters at first refused to set off the charges, but after Ed and the labor crew convinced them (some members on the labor crew were anxious for Ed to try out his “brilliant idea) that there really wouldn’t be much lost if the worst happened, they went ahead and set off the dynamite.

Needless to say…. Ed came wobbling his way out of the boiler like a cracked boiled egg and said in a shaky voice, “I don’t think that would be such a good idea.” All of us on the Labor Crew said to each other, “..As if we needed him to tell us that.” I think that may be a day that Ed Hutchins would like to take back. The day he learned the real meaning of “Concussion”. I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

    When you have pallets double-stacked, you should only move them about with a pallet jack. The bottom pallet – and whatever is stacked on it – is thoroughly supported. And even if the pallet jack is powered, you aren’t likely to get in trouble with rapid acceleration.

    As you would with a fork lift truck.

    And the double stacked pallets are truck mirrors boxed for shipment to retailers. A couple hundred mirrors. And I dumped both pallets when I went to back up and turn into the warehouse aisle.

    Modern parables like these are much too good to waste! They should be included in every freshman Congressman’s Washington Welcome Kit when he first takes office and new ‘reminder’ versions again every time he wins an election. These are wonderful essays on unintended consequences, at which our Congress is among the best!

      I worked with Ed on the Precipitator control replacement project (84 controls X 2) in 2006 I think. He was getting ready to retire at the time. He was a good engineer and a tough customer. I was working for the control supplier and those 168 controls were the first installation of a brand new control design. I had lead the design team for the controls and this was the culmination of our work. I spend more days and nights than I can remember going up and down the aisles of controls loading software fixes into the processors! Anyway, great people at the plant and great memories… including a rapper control cabinet that took the express route to the ground elevation from the precip roof! (ouch, it really is the sudden stop that gets you!)

        Thanks for the comment John! It’s good to hear about improvements to the Precipitator and the control rooms I used to call home.  I spend many weekends walking back and forth through those control rooms.

      OMG – The very thought of a group staying in the boiler when the dynamite went off! Thank goodness THAT didn’t happen. I felt the tension just reading that bit. I’m glad Ed came out of it all right.

Learnin’ ’bout ‘lectricity with Andy Tubbs

Originally posted January 18, 2013:

The day I became an electrician at the coal-fired power plant, I suddenly became an expert in electricity. I think it was on Tuesday, just one day after joining the electric shop that I was walking through the welding shop when someone stopped me and asked me how they would wire their living room with different light switches at different corners and make it work correctly. As if I had been an electrician for years. Luckily I was just finishing a house wiring course at the Indian Meridian Vo-Tech in Stillwater, Oklahoma and they had us figure out problems just like those.

Within the first week, George Alley brought a ceiling fan to the shop that he had picked up somewhere and was wondering if we could get it to work. My foreman Charles Foster thought it would be a good small project for me to work on to help me learn about electrical circuits.

After all, this ceiling fan could go slow, medium and fast, and it could go forward or reverse. Only at the moment, all it would do was sit there and hum when you hooked up the power. — So that was my first “unofficial” project, since the main goal was to make George happy so that he would help us out when we needed something special from the mechanics.

When I was a janitor, I had observed the electricians preparing to go to work in the morning, and often, one of them would go to the print cabinets at one end of the shop and pull out a blueprint and lay it across the work table and study it for a while. Then they would either put it back or fold it and put it in their tool bucket and head out the door to go do a job. Now, it was my turn.

Andy Tubbs was one of the two people that played the best jokes on me when I was a janitor. Larry Burns was the other person, and he was the person I was replacing as he had moved to another plant. Andy was the one that had taken the handle off of my push broom the moment I had my back turned so that when I turned around to grab my broom, only the broom head was on the floor, while the broom handle was across the counter by the lab, and Andy was across the other side of the room trying to act like he wasn’t paying attention, but with an expression like he had just played a darn good joke. — I actually had to go back into the bathroom I was cleaning so that I could laugh out loud. I was really impressed by Andy’s ability to play a good joke.

While I’m on the subject, shortly after I became an electrician, I was sitting in the electric shop office talking to Charles when he stopped and said, “Wait…. Listen….” We paused, waiting for something…. A few seconds later, the sound of a hoot owl came over the PA system (what we called the “Gray Phone”). Charles said, It’s an interesting coincidence that the only time the perfect sound of a hoot owl comes over the Gray Phone is when Andy Tubbs is riding in an elevator by himself or with a close friend.

I had been sent with Andy Tubbs and Diana Lucas (later Diana Brien), to go to the coal yard and figure out why some circuit for the train gate was not working. Andy had pulled out the blueprints and was studying them. I came up alongside him and looked at all the blue lines running here and there with circles with letters and numbers, and what I recognized as open and closed switches….

Here is a simple electric circuit drawn in the style of many of the electric blueprint drawings

Andy stopped and gave me a momentary lecture on the nature of electricity. It was so perfectly summed up, that for years whenever I thought about the nature of electricity, I always began with remembering what Andy told me. He said this:

“Think of electricity like water in a hose. Voltage is the water pressure. Amperage is the amount of water going through the hose. You can have the nozzle on the end of the hose shut off so that no water is coming out and then you have no amperage, but you will still have the pressure as long as it is turned on at the source so you will still have voltage.”

“In these diagrams, you just have to figure out how the water is going to get from one side to the other. These circles are things like relays or lights or motors. When the electricity makes it through them, they turn on as long as the electricity can make it all the way to the other side.”

That was it! That was my lesson in ‘lectricity. All I needed to know. The blueprints were big puzzles. I loved working puzzles. You just had to figure out how you were going to get something to run, and that meant that certain relays had to pickup to close switches that might pick up other relays to close other switches. I found that most of the electricians in the shop were good at working all sorts of puzzles.

Andy went to the cabinet and grabbed one of the Simpson multimeters and a handset for a telephone that had red and black wires wrapped around it.

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

I was puzzled by this at first. I thought I would just wait to see what we did with it instead of ask what it was for. We grabbed our tool buckets (which also doubled as a stool and tripled as a trash can as needed), and put them in the substation truck. The other truck was being manned by the designated electrician truck driver for that week. We needed a truck that we could drive around in without having to hold up the truck driver.

We drove to the coalyard and went into the dumper switchgear. Andy and Diane opened up a large junction box that was full of terminal blocks with wires going every which way in an orderly fashion. They located a couple of wires, and Andy unwrapped the wires from the handset while Diane removed the screws holding the wires to the terminal block. Then Andy clipped one wire from the telephone handset to each of the two wires and handed me the phone.

Diane told me that they were going to drive down toward the train gate where the railroad tracks come into the plant and try to find these wires on the other end. So, what they needed me to do was to talk on the phone so when they find my voice, they will know that they have the right wires. Diane said, “Just say anything.” Then they left the switchgear and I could hear them drive away in the truck.

Well. This was my opportunity to just talk to no one for a while without interruption. How many times do you get to do that in one day? Probably only when you are on the way to work and back again if you aren’t carpooling with anyone. Or you’re sittin’ on your “thinkin’ chair” in a single occupant restroom. So, I just kicked into Ramblin’ Ann mode and let myself go. I believe my monologue went something like this:

“The other day I was walking through a field, and who should I run across, but my old friend Fred. I said, ‘Well, Hi Fred, how is it going?’ and Fred told me that he was doing just fine, but that he had lost his cow and was wondering if I could help him look for it. I told him I couldn’t right now because I was helping some people find a wire at the moment, and if I became distracted, we might not only lose the cow, but we might lose the wires as well, so I better just keep on talking so that my friends on the other end can find the wires they are looking for. After that I went to the store and I picked up three cans of peas. I thought about getting four cans of peas but settled on three and brought them to the checkout counter, and while I was waiting in line I noticed that the little boy in front of me with his mom was looking at me as if he wanted to have one of my cans of peas, so I quickly made it clear to him that I was buying these cans of peas for myself by sliding them further away from him and glaring at him. Luckily the boy wasn’t persistent otherwise I would have broken down and given him a can of peas because he was looking kind of hungry and I was feeling sorry for him, though, I didn’t want him to know how I was feeling, so I put on a grim expression….”

Needless to say… My monologue went on for another 15 minutes. Yes… .15 minutes. I had expected Andy and Diane to have returned earlier, but I didn’t know how hard it was going to be to find the other end of the wires, so I just kept on ramblin’ to the best of my ability. It’s like what it says in the Bible. If we wrote down everything I said, it would have filled many volumes. Being a Disciple of Ramblin’ Ann came in handy that day. For more about Ramblin’ Ann, you can read the following post:

Ed Shiever Trapped in a Confined Space With A Disciple of Ramblin’ Ann

When Andy and Diane returned they said that they had found the wires right away, but that they had sat there for a while just listening to me ramble. They said I was cracking them up. They also mentioned that they thought I was completely crazy. Well. I was glad that they found the wires and that my rambling abilities had come in handy.

Five months after I had joined the electric shop, Andy and I were sent to Oklahoma City to learn about a new kind of electric troubleshooting. It was called “Digital Electronics”. I had just finished my electronics class at the Vo-Tech, and so I was eager to put it into practice. Andy and I went to a two day seminar where we learned to troubleshoot what was basically a PC motherboard of 1984. We used a special tool called a digital probe and learned how the processor worked with the memory chips and the bios. It wasn’t like a motherboard is today. It was simple.

A simple Motherboard like this

It was just designed for the class so that we could use the digital probe to follow the different leads from the chips as the electric pulses turned on and off.

We were using digital probes similar to this

At the time I was thinking that this was a waste of time. I had been learning all about troubleshooting electronic circuits from Bill Rivers and Sonny Kendrick. I couldn’t see how this was going to be useful. I didn’t know that within a couple of years, most of our electronic circuits in the precipitator controls were all going to be replaced with digital controls, and this was exactly what I was going to need to know.

So, Andy and I spent two days learning all the basics of how new computers were going to be working. This was the same year that Michael Dell was beginning his new computer company further down I-35 in Austin Texas. Who would have thought that 18 years later I would be working for Dell. But that’s another lifetime away…

Early in my career at the Seminole Plant I learned when someone paged you on the gray phone, you should always check the earpiece of the phone before you put it on your ear – it might be full of clear silicone calk (or worse). Also, at the end of the day when you reach to pick up your lunch box, you should pick it up gently. Someone could have slipped a full bottle of mercury (like 20 pounds) in it. This prevents you from pulling the handle off your lunch box or hearing it crash to the floor, smashing everything in its path. It’s amazing what Power Plant Men are capable of doing.

    We used hand lotion in the electric shop for the gray phone trick. I remember Andy catching an unsuspecting operator in the main switchgear more than once.

The day he learned the real meaning of “Concussion”. I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

    When you have pallets double-stacked, you should only move them about with a pallet jack. The bottom pallet – and whatever is stacked on it – is thoroughly supported. And even if the pallet jack is powered, you aren’t likely to get in trouble with rapid acceleration.

    As you would with a fork lift truck.

    And the double stacked pallets are truck mirrors boxed for shipment to retailers. A couple hundred mirrors. And I dumped both pallets when I went to back up and turn into the warehouse aisle.

    Modern parables like these are much too good to waste! They should be included in every freshman Congressman’s Washington Welcome Kit when he first takes office and new ‘reminder’ versions again every time he wins an election. These are wonderful essays on unintended consequences, at which our Congress is among the best!

      I worked with Ed on the Precipitator control replacement project (84 controls X 2) in 2006 I think. He was getting ready to retire at the time. He was a good engineer and a tough customer. I was working for the control supplier and those 168 controls were the first installation of a brand new control design. I had lead the design team for the controls and this was the culmination of our work. I spend more days and nights than I can remember going up and down the aisles of controls loading software fixes into the processors! Anyway, great people at the plant and great memories… including a rapper control cabinet that took the express route to the ground elevation from the precip roof! (ouch, it really is the sudden stop that gets you!)

        Thanks for the comment John! It’s good to hear about improvements to the Precipitate and the control rooms I used to call home.

      OMG – The very thought of a group staying in the boiler when the dynamite went off! Thank goodness THAT didn’t happen. I felt the tension just reading that bit. I’m glad Ed came out of it all right.

Learnin’ ’bout ‘lectricity with Andy Tubbs

Originally posted January 18, 2013:

The day I became an electrician at the coal-fired power plant, I suddenly became an expert in electricity. I think it was on Tuesday, just one day after joining the electric shop that I was walking through the welding shop when someone stopped me and asked me how they would wire their living room with different light switches at different corners and make it work correctly. As if I had been an electrician for years. Luckily I was just finishing a house wiring course at the Indian Meridian Vo-Tech in Stillwater, Oklahoma and they had us figure out problems just like those.

Within the first week, George Alley brought a ceiling fan to the shop that he had picked up somewhere and was wondering if we could get it to work. My foreman Charles Foster thought it would be a good small project for me to work on to help me learn about electrical circuits. After all, this ceiling fan could go slow, medium and fast, and it could go forward or reverse. Only at the moment, all it would do was sit there and hum when you hooked up the power. — So that was my first “unofficial” project, since the main goal was to make George happy so that he would help us out when we needed something special from the mechanics.

When I was a janitor, I had observed the electricians preparing to go to work in the morning, and often, one of them would go to the print cabinets at one end of the shop and pull out a blueprint and lay it across the work table and study it for a while. Then they would either put it back or fold it and put it in their tool bucket and head out the door to go do a job. Now, it was my turn.

Andy Tubbs was one of the two people that played the best jokes on me when I was a janitor. Larry Burns was the other person, and he was the person I was replacing as he had moved to another plant. Andy was the one that had taken the handle off of my push broom the moment I had my back turned so that when I turned around to grab my broom, only the broom head was on the floor, while the broom handle was across the counter by the lab, and Andy was across the other side of the room trying to act like he wasn’t paying attention, but with an expression like he had just played a darn good joke. — I actually had to go back into the bathroom I was cleaning so that I could laugh out loud. I was really impressed by Andy’s ability to play a good joke.

While I’m on the subject, shortly after I became an electrician, I was sitting in the electric shop office talking to Charles when he stopped and said, “Wait…. Listen….” We paused, waiting for something…. A few seconds later, the sound of a hoot owl came over the PA system (what we called the “Gray Phone”). Charles said, It’s an interesting coincidence that the only time the perfect sound of a hoot owl comes over the Gray Phone is when Andy Tubbs is riding in an elevator by himself or with a close friend.

I had been sent with Andy Tubbs and Diana Lucas (later Diana Brien), to go to the coal yard and figure out why some circuit for the train gate was not working. Andy had pulled out the blueprints and was studying them. I came up alongside him and looked at all the blue lines running here and there with circles with letters and numbers, and what I recognized as open and closed switches….

Here is a simple electric circuit drawn in the style of many of the electric blueprint drawings

Andy stopped and gave me a momentary lecture on the nature of electricity. It was so perfectly summed up, that for years whenever I thought about the nature of electricity, I always began with remembering what Andy told me. He said this:

“Think of electricity like water in a hose. Voltage is the water pressure. Amperage is the amount of water going through the hose. You can have the nozzle on the end of the hose shut off so that no water is coming out and then you have no amperage, but you will still have the pressure as long as it is turned on at the source so you will still have voltage. In these diagrams, you just have to figure out how the water is going to get from one side to the other. These circles are things like relays or lights or motors. When the electricity makes it through them, they turn on as long as the electricity can make it all the way to the other side.”

That was it! That was my lesson in ‘lectricity. All I needed to know. The blueprints were big puzzles. I loved working puzzles. You just had to figure out how you were going to get something to run, and that meant that certain relays had to pickup to close switches that might pick up other relays to close other switches. I found that most of the electricians in the shop were good at working all sorts of puzzles.

Andy went to the cabinet and grabbed one of the Simpson multimeters and a handset for a telephone that had red and black wires wrapped around it.

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

I was puzzled by this at first. I thought I would just wait to see what we did with it instead of ask what it was for. We grabbed our tool buckets (which also doubled as a stool and tripled as a trash can as needed), and put them in the substation truck. The other truck was being manned by the designated electrician truck driver for that week. We needed a truck that we could drive around in without having to hold up the truck driver.

We drove to the coalyard and went into the dumper switchgear. Andy and Diane opened up a large junction box that was full of terminal blocks with wires going every which way in an orderly fashion. They located a couple of wires, and Andy unwrapped the wires from the handset while Diane removed the screws holding the wires to the terminal block. Then Andy clipped one wire from the handset to each of the two wires and handed me the phone.

Diane told me that they were going to drive down toward the train gate where the railroad tracks come into the plant and try to find these wires on the other end. So, what they needed me to do was to talk on the phone so when they find my voice, they will know that they have the right wires. Diane said, “Just say anything.” Then they left the switchgear and I could hear them drive away in the truck.

Well. This was my opportunity to just talk to no one for a while without interruption. How many times do you get to do that in one day? Probably only when you are on the way to work and back again if you aren’t carpooling with anyone. Or you’re sittin’ on your “thinkin’ chair” in a single occupant restroom. So, I just kicked into Ramblin’ Ann mode and let myself go. I believe my monologue went something like this:

“The other day I was walking through a field, and who should I run across, but my old friend Fred. I said, ‘Well, Hi Fred, how is it going?’ and Fred told me that he was doing just fine, but that he had lost his cow and was wondering if I could help him look for it. I told him I couldn’t right now because I was helping some people find a wire at the moment, and if I became distracted, we might not only lose the cow, but we might lose the wires as well, so I better just keep on talking so that my friends on the other end can find the wires they are looking for. After that I went to the store and I picked up three cans of peas. I thought about getting four cans of peas but settled on three and brought them to the checkout counter, and while I was waiting in line I noticed that the little boy in front of me with his mom was looking at me as if he wanted to have one of my cans of peas, so I quickly made it clear to him that I was buying these cans of peas for myself by sliding them further away from him and glaring at him. Luckily the boy wasn’t persistent otherwise I would have broken down and given him a can of peas because he was looking kind of hungry and I was feeling sorry for him, though, I didn’t want him to know how I was feeling, so I put on a grim expression….”

Needless to say… My monologue went on for another 15 minutes. Yes… .15 minutes. I had expected Andy and Diane to have returned earlier, but I didn’t know how hard it was going to be to find the other end of the wires, so I just kept on ramblin’ to the best of my ability. It’s like what it says in the Bible. If we wrote down everything I said, it would have filled many volumes. Being a Disciple of Ramblin’ Ann came in handy that day. For more about Ramblin’ Ann, you can read the following post:

Ed Shiever Trapped in a Confined Space With A Disciple of Ramblin’ Ann

When Andy and Diane returned they said that they had found the wires right away, but that they had sat there for a while just listening to me ramble. They said I was cracking them up. They also mentioned that they thought I was completely crazy. Well. I was glad that they found the wires and that my rambling abilities had come in handy.

Five months after I had joined the electric shop, Andy and I were sent to Oklahoma City to learn about a new kind of electric troubleshooting. It was called “Digital Electronics”. I had just finished my electronics class at the Vo-Tech, and so I was eager to put it into practice. Andy and I went to a two day seminar where we learned to troubleshoot what was basically a PC motherboard of 1984. We used a special tool called a digital probe and learned how the processor worked with the memory chips and the bios. It wasn’t like a motherboard is today. It was simple.

A simple Motherboard like this

A simple Motherboard like this

It was just designed for the class so that we could use the digital probe to follow the different leads from the chips as the electric pulses turned on and off.

We were using digital probes similar to this

At the time I was thinking that this was a waste of time. I had been learning all about troubleshooting electronic circuits from Bill Rivers and Sonny Kendrick. I couldn’t see how this was going to be useful. I didn’t know that within a couple of years, most of our electronic circuits in the precipitator controls were all going to be replaced with digital controls, and this was exactly what I was going to need to know.

So, Andy and I spent two days learning all the basics of how new computers were going to be working. This was the same year that Michael Dell was beginning his new computer company further down I-35 in Austin Texas. Who would have thought that 18 years later I would be working for Dell. But that’s another lifetime away…

Early in my career at the Seminole Plant I learned when someone paged you on the gray phone, you should always check the earpiece of the phone before you put it on your ear – it might be full of clear silicone calk (or worse). Also, at the end of the day when you reach to pick up your lunch box, you should pick it up gently. Someone could have slipped a full bottle of mercury (like 20 pounds) in it. This prevents you from pulling the handle off your lunch box or hearing it crash to the floor, smashing everything in its path. It’s amazing what Power Plant Men are capable of doing.

    We used hand lotion in the electric shop for the gray phone trick. I remember Andy catching an unsuspecting operator in the main switchgear more than once.

Cracking a Boiled Egg in the Boiler and Other Days You Wish You Could Take Back — Repost

There are some days you wish you could take back after making a grand decision that turns out to look really dumb when your decision fails. It is important to think outside the box to break new ground as long as you bring common sense along for the ride. It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.

It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).

To name a couple of minor “Faux Pas” (how do you pluralize that word? I don’t know), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.

The first two stories both involve the Electrical Supervisors of two different Power Plants.

Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps. This was a reoccurring problem that required a lot of man hours to repair. The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.

A Bottom Ash Overflow Sump Pump or BAOSP for Short

So, Tom Gibson decided that he was going to fill the motor and pump cavity with turbine oil. All electricians knew that oil used in turbines is an insulator so electrically it wouldn’t short anything out. But something in the back of your mind automatically says that this isn’t going to work. I remember helping to fill the motor up with oil in the Maintenance shop and hooking up some motor leads from the nearby Maintenance shop 480 volt switchgear. Needless to say, as soon as the pump was turned on, it tripped the breaker and oil began leaking from the cable grommet. That’s when common sense tells you that the all the oil causes too much drag on the rotor which will cause a 480 motor to trip very quickly. After removing some of the oil and trying it again with a larger breaker and still having the same result Tom was satisfied that this just wasn’t going to work. The pump and motor was sent away to a nearby electric shop to be rewound and other ways were developed by the help of our top notch machinist genius Randy Dailey who came up with a positive air pressure way to keep water out of the Bottom Ash Overflow Sump Pump and motor (also known as the BAOSP). Not much harm done and Tom Gibson didn’t feel too bad for trying something that the rest of us sort of thought was mildly insane.

The next story was told to me by my dear friend Bob Kennedy when I was working at a Gas Powered Plant in Midwest City and he was my acting foreman. So I didn’t witness this myself. This one was a little more dangerous, but still thankfully, no one was hurt. Ellis Rooks, the Electrical Supervisor needed to bump test a 4200 Volt motor and wanted to do it in place. For some reason he was not able to use the existing cables, maybe because that was the reason the motor was offline. Because one of the cables had gone to ground. So, he decided that since the motor only pulled 5 to 10 amps he could use #10 wire and string three of them (for the three phases of the motor) from the main High Voltage switchgear across the turbine room floor over to the motor. Now, most electricians know how many amps different size wires can generally handle. It goes like this: #14 – 15 amps, #12 – 20 amps, #10 – 30 amps, #8 – 50 amps and on down (smaller numbers mean bigger wires). So, Ellis thought that since the motor only pulls around 5 amps, and he only wanted to bump the motor (that is, turn it on and off quickly) to watch it rotate, he thought that even though there was normally a 3 – 0 cable (pronounced three aught for 3 zeroes, very large wire), this would be ok because he was only going to bump it.

This works when you are using is 120 or 220 volts

Needless to say, but I will anyway, when the motor was bumped, all that was left were three black streaks of carbon across the turbine room floor where the wire used to exist before it immediately vaporized. You see, common sense tells you that 4200 volts times 5 amps = 21,000 watts of power. However, the starting amps on a motor like this may be around 50 to 100 amps, which would equal 210 to 420 Kilowatts of power (or about 1/5 to 2/5 of a Megawatt). Thus vaporizing the small size 10 wire that is used to wire your house.

All right. I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler. This happened when I was still a janitor but was loaned to the Labor Crew during outages. When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler. Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must. Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected. It wasn’t easy looking like a pole with no shoulders, but I tried my best. I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this.

Before we could get into the boiler to start shaking tubes, the dynamiters would go in there first and blow up the bigger clinkers. So, for a couple of days some times, at the beginning of an overhaul, you would hear someone come over the PA system about every 20 minutes saying, “Stand Clear of Number One Boiler, We’re Gonna Blast!!!” This became so common to hear over the years that unless you were up on the boiler helping out, you didn’t pay any attention to it.

This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers. Maybe some Soot, I don’t know, but not Ash. Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul. We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area. We brought our large toolbox and other equipment over to the motor. Andy Tubbs and Diana Brien were there with Reggie and I. I think Gary Wehunt was there with us also. When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency. Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.

Anyway. That wasn’t the day that someone wished they could take back, but I thought I would throw that one in anyway so that now Reggie will wish that he could take back that day.

When I was on Labor Crew, and we were waiting on the boiler for the dynamiters to blast all the large clinkers, the engineer in charge, Ed Hutchins decided that things would go a lot quicker if all the laborers would go into the boiler and shake tubes while the dynamiters were setting their charges. Then we would climb out when they were ready to blast, and then go back in. So, we did that. All 10 or so of us climbed into the boiler, and went to work rattling boiler tubes until we heard someone yell, “Fire In The Hole!!!” Then we would all head for the one entrance and climb out and wait for the blast.

The extra time it took to get all of us in the boiler and back out again actually slowed everything down. We weren’t able to get much work done each time, and everyone spent most of their time climbing in and out instead of working, including the dynamiters. So Ed had another brilliant idea. What if we stayed in the boiler while the dynamite exploded? Then we wouldn’t be wasting valuable time climbing in and out and really wouldn’t have to stop working at all.

Of course, common sense was telling us that we didn’t want to be in an enclosed boiler while several sticks worth of dynamite all exploded nearby, so the engineer decided to prove to us how safe it was by standing just inside the entrance of the boiler with his ear plugs in his ears while the dynamite exploded. The dynamiters at first refused to set off the charges, but after Ed and the labor crew convinced them that there really wouldn’t be much lost if the worst happened, they went ahead and set off the dynamite.

Needless to say…. Ed came wobbling his way out of the boiler like a cracked boiled egg and said in a shaky voice, “I don’t think that would be such a good idea.” All of us on the Labor Crew said to each other, “..As if we needed him to tell us that.” I think that may be a day that Ed Hutchins would like to take back. The day he learned the real meaning of “Concussion”. I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

Five months after I had joined the electric shop, Andy and I were sent to Oklahoma City to learn about a new kind of electric troubleshooting.  It was called “Digital Electronics”.  I had just finished my electronics class at the Vo-Tech, and so I was eager to put it into practice.  Andy and I went to a two day seminar where we learned to troubleshoot what was basically a PC motherboard of 1984.  We used a special tool called a digital probe and learned how the processor worked with the memory chips and the bios.  It wasn’t like a motherboard is today.  It was simple.

It was just designed for the class so that we could use the digital probe to follow the different leads from the chips as the electric pulses turned on and off.

At the time I was thinking that this was a waste of time.  I had been learning all about troubleshooting electronic circuits from Bill Rivers and Sonny Kendrick.  I couldn’t see how this was going to be useful.  I didn’t know that within a couple of years, most of our electronic circuits in the precipitator controls were all going to be replaced with digital controls, and this was exactly what I was going to need to know.

So, Andy and I spent two days learning  all the basics of how new computers were going to be working.  This was the same year that Michael Dell was beginning his new computer company further down I-35 in Austin Texas.  Who would have thought that 18 years later I would be working for Dell.  But that’s another lifetime away…

Early in my career at the Seminole Plant I learned when someone paged you on the gray phone, you should always check the earpiece of the phone before you put it on your ear – it might be full of clear silicone calk (or worse). Also, at the end of the day when you reach to pick up your lunch box, you should pick it up gently. Someone could have slipped a full bottle of mercury (like 20 pounds) in it. This prevents you from pulling the handle off your lunch box or hearing it crash to the floor, smashing everything in its path. It’s amazing what Power Plant Men are capable of doing.

    We used hand lotion in the electric shop for the gray phone trick. I remember Andy catching an unsuspecting operator in the main switchgear more than once.

Cracking a Boiled Egg in the Boiler and Other Days You Wish You Could Take Back — Repost

There are some days you wish you could take back after making a grand decision that turns out to look really dumb when your decision fails.  It is important to think outside the box to break new ground as long as you bring common sense along for the ride.  It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.

It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).

To name a couple of minor “Faux Pas” (how do you pluralize that word?  I don’t know), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.

The first two stories both involve the Electrical Supervisors of two different Power Plants.

Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps.  This was a reoccurring problem that required a lot of man hours to repair.  The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.

A Bottom Ash Overflow Sump Pump or BAOSP for Short

So, Tom Gibson decided that he was going to fill the motor and pump cavity with turbine oil.  All electricians knew that oil used in turbines is an insulator so electrically it wouldn’t short anything out.  But something in the back of your mind automatically says that this isn’t going to work.  I remember helping to fill the motor up with oil in the Maintenance shop and  hooking up some motor leads from the nearby Maintenance shop 480 volt switchgear.  Needless to say, as soon as the pump was turned on, it tripped the breaker and oil began leaking from the cable grommet.  That’s when common sense tells you that the all the oil causes too much drag on the rotor which will cause a 480 motor to trip very quickly.  After removing some of the oil and trying it again with a larger breaker and still having the same result Tom was satisfied that this just wasn’t going to work.  The pump and motor was sent away to a nearby electric shop to be rewound and other ways were developed by the help of our top notch machinist genius Randy Dailey who came up with a positive air pressure way to keep water out of the Bottom Ash Overflow Sump Pump and motor (also known as the BAOSP).  Not much harm done and Tom Gibson didn’t feel too bad for trying something that the rest of us sort of thought was mildly insane.

The next story was told to me by my dear friend Bob Kennedy when I was working at a Gas Powered Plant in Midwest City and he was my acting foreman.  So I didn’t witness this myself.  This one was a little more dangerous, but still thankfully, no one was hurt.  Ellis Rooks, the Electrical Supervisor needed to bump test a 4200 Volt motor and wanted to do it in place.  For some reason he was not able to use the existing cables, maybe because that was the reason the motor was offline.  Because one of the cables had gone to ground.  So, he decided that since the motor only pulled 5 to 10 amps he could use #10 wire and string three of them (for the three phases of the motor) from the main High Voltage switchgear across the turbine room floor over to the motor.  Now, most electricians know how many amps different size wires can generally handle.  It goes like this: #14 – 15 amps, #12 – 20 amps, #10 – 30 amps, #8 – 50 amps and on down (smaller numbers mean bigger wires).  So, Ellis thought that since the motor only pulls around 5 amps, and he only wanted to bump the motor (that is, turn it on and off quickly) to watch it rotate, he thought that even though there was normally a 3 – 0 cable (pronounced three aught for 3 zeroes, very large wire), this would be ok because he was only going to bump it.

This works when you are using is 120 or 220 volts

Needless to say, but I will anyway, when the motor was bumped, all that was left were three black streaks of carbon across the turbine room floor where the wire used to exist before it immediately vaporized.  You see, common sense tells you that 4200 volts times 5 amps = 21,000 watts of power.  However, the starting amps on a motor like this may be around 50 to 100 amps, which would equal 210 to 420 Kilowatts of power (or about 1/5  to 2/5 of a Megawatt). Thus vaporizing the small size 10 wire that is used to wire your house.

All right.  I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler.  This happened when I was still a janitor but was loaned to the Labor Crew during outages.  When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler.  Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must.  Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected.  It wasn’t easy looking like a pole with no shoulders, but I tried my best.  I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this.

Before we could get into the boiler to start shaking tubes, the dynamiters would go in there first and blow up the bigger clinkers.  So, for a couple of days some times, at the beginning of an overhaul, you would hear someone come over the PA system about every 20 minutes saying, “Stand Clear of Number One Boiler, We’re Gonna Blast!!!”  This became so common to hear over the years that unless you were up on the boiler helping out, you didn’t pay any attention to it.

This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers.  Maybe some Soot, I don’t know, but not Ash.  Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul.  We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area.  We brought our large toolbox and other equipment over to the motor.  Andy Tubbs and Diana Brien were there with Reggie and I.  I think Gary Wehunt was there with us also.  When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency.  Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.

Anyway.  That wasn’t the day that someone wished they could take back, but I thought I would throw that one in anyway so that now Reggie will wish that he could take back that day.

When I was on Labor Crew, and we were waiting on the boiler for the dynamiters to blast all the large clinkers, the engineer in charge, Ed Hutchins decided that things would go a lot quicker if all the laborers would go into the boiler and shake tubes while the dynamiters were setting their charges.  Then we would climb out when they were ready to blast, and then go back in.  So, we did that.  All 10 or so of us climbed into the boiler, and went to work rattling boiler tubes until we heard someone yell, “Fire In The Hole!!!”  Then we would all head for the one entrance and climb out and wait for the blast.

The extra time it took to get all of us in the boiler and back out again actually slowed everything down.  We weren’t able to get much work done each time, and everyone spent most of their time climbing in and out instead of working, including the dynamiters.  So Ed had another brilliant idea.  What if we stayed in the boiler while the dynamite exploded?  Then we wouldn’t be wasting valuable time climbing in and out and really wouldn’t have to stop working at all.

Of course, common sense was telling us that we didn’t want to be in an enclosed boiler while several sticks worth of dynamite all exploded nearby, so the engineer decided to prove to us how safe it was by standing just inside the entrance of the boiler with his ear plugs in his ears while the dynamite exploded.  The dynamiters at first refused to set off the charges, but after Ed and the labor crew convinced them that there really wouldn’t be much lost if the worst happened, they went ahead and set off the dynamite.

Needless to say…. Ed came wobbling his way out of the boiler like a cracked boiled egg and said in a shaky voice, “I don’t think that would be such a good idea.”  All of us on the Labor Crew said to each other, “..As if we needed him to tell us that.”  I think that may be a day that Ed Hutchins would like to take back.  The day he learned the real meaning of “Concussion”.  I think he was promoted shortly after that and went to work in Oklahoma City at Corporate Headquarters.

  • When you have pallets double-stacked, you should only move them about with a pallet jack. The bottom pallet – and whatever is stacked on it – is thoroughly supported. And even if the pallet jack is powered, you aren’t likely to get in trouble with rapid acceleration.

    As you would with a fork lift truck.

    And the double stacked pallets are truck mirrors boxed for shipment to retailers. A couple hundred mirrors. And I dumped both pallets when I went to back up and turn into the warehouse aisle.

  • :) Thanks for that. I have a few of those days myself that I will probably share in later posts. :)

  • Modern parables like these are much too good to waste! They should be included in every freshman Congressman’s Washington Welcome Kit when he first takes office and new ‘reminder’ versions again every time he wins an election. These are wonderful essays on unintended consequences, at which our Congress is among the best!

Learnin’ ’bout ‘lectricity with Andy Tubbs

The day I became an electrician at the coal-fired power plant, I suddenly became an expert in electricity.  I think it was on Tuesday, just one day after joining the electric shop that I was walking through the welding shop when someone stopped me and asked me how they would wire their living room with different light switches at different corners and make it work correctly.  As if I had been an electrician for years.  Luckily I  was just finishing a house wiring course at the Indian Meridian Vo-Tech in Stillwater, Oklahoma and they had us figure out problems just like those.

Within the first week, George Alley brought a ceiling fan to the shop that he had picked up somewhere and was wondering if we could get it to work.  My foreman Charles Foster thought it would be a good small project for me to work on to help me learn about electrical circuits.  After all, this ceiling fan could go slow, medium and fast, and it could go forward or reverse.  Only at the moment, all it would do was sit there and hum when you hooked up the power.  — So that was my first “unofficial” project, since the main goal was to make George happy so that he would help us out when we needed something special from the mechanics.

When I was a janitor, I had observed the electricians preparing to go to work in the morning, and often, one of them would go to the print cabinets at one end of the shop and pull out a blue print and lay it across the work table and study it for a while.  Then they would either put it back or fold it and put it in their tool bucket and head out the door to go do a job.  Now, it was my turn.

Andy Tubbs was one of the two people that played the best jokes on me when I was a janitor.  Larry Burns was the other person, and he was the person I was replacing as he had moved to another plant.  Andy was the one that had taken the handle off of my push broom the moment I had my back turned so that when I turned around to grab my broom, only the broom head was on the floor, while the broom handle was across the counter by the lab, and Andy was across the other side of the room trying to act like he wasn’t paying attention, but with an expression like he had just played a darn good joke.  — I actually had to go back into the bathroom I was cleaning so that I could laugh out loud.  I was really impressed by Andy’s ability to play a good joke.

While I’m on the subject, shortly after I became an electrician, I was sitting in the electric shop office talking to Charles when he stopped and said, “Wait…. Listen….”  We paused, waiting for something….  A few seconds later, the sound of a hoot owl came over the PA system (what we called the “Gray Phone”).  Charles said,  It’s an interesting coincidence that the only time the perfect sound of a hoot owl comes over the Gray Phone is when Andy Tubbs is riding in an elevator by himself or with a close friend.

I had been sent with Andy Tubbs and Diana Lucas (later Diana Brien), to go to the coal yard and figure out why some circuit for the train gate was not working.  Andy had pulled out the blueprints and was studying them.  I came up alongside him and looked at all the blue lines running here and there with circles with letters and numbers, and what I recognized as open and closed switches….

Here is a simple electric circuit drawn in the style of many of the electric blueprint drawings

Andy stopped and gave me a momentary lecture on the nature of electricity.  It was so perfectly summed up, that for years whenever I thought about the nature of electricity, I always began with remembering what Andy told me.  He said this:

“Think of electricity like water in a hose.  Voltage is the water pressure.  Amperage is the amount of water going through the hose.  You can have the nozzle on the end of the hose shut off so that no water is coming out and then you have no amperage, but you will still have the pressure as long as it is turned on at the source so you will still have voltage.  In these diagrams, you just have to figure out how the water is going to get from one side to the other.  These circles are things like relays or lights or motors.  When the electricity makes it through them, they turn on as long as the electricity can make it all the way to the other side.”

That was it!  That was my lesson in ‘lectricity.  All I needed to know.  The blueprints were big puzzles.  I loved working puzzles.  You just had to figure out how you were going to get something to run, and that meant that certain relays had to pickup to close switches that might pick up other relays to close other switches. I found that most of the electricians in the shop were good at working all sorts of puzzles.

Andy went to the cabinet and grabbed one of the Simpson multimeters and a handset for a telephone that had red and black wires wrapped around it.

A telephone handset that looked like this, only it had a battery taped to it, and two leads coming out the bottom

I was puzzled by this at first.  I thought I would just wait to see what we did with it instead of ask what it was for.  We grabbed our tool buckets (which also doubled as a stool and tripled as a trash can as needed), and put them in the substation truck.  The other truck was being manned by the designated electrician truck driver for that week.  We needed a truck that we could drive around in without having to hold up the truck driver.

We drove to the coalyard and went into the dumper switchgear.  Andy and Diane opened up a large junction box that was full of terminal blocks with wires going every which way in an orderly fashion.  They located a couple of wires, and Andy unwrapped the wires from the handset while Diane removed the screws holding the wires to the terminal block.  Then Andy clipped one wire from the handset to each of the two wires and handed me the phone.

Diane told me that they were going to drive down toward the train gate where the railroad tracks come into the plant and try to find these wires on the other end.  So, what they needed me to do was to talk on the phone so when they find my voice, they will know that they  have the right wires.  Diane said, “Just say anything.”  Then they left the switchgear and I could hear them drive away in the truck.

Well.  This was my opportunity to just talk to no one for a while without interruption.  How many times do you get to do that in one day?  Probably only when you are on the way to work and back again if you aren’t carpooling with anyone.  So, I just kicked into Ramblin’ Ann mode and let myself go.  I believe my monologue went something like this:

“The other day I was walking through a field, and who should I run across, but my old friend Fred.  I said, ‘Well, Hi Fred, how is it going?’ and Fred told me that he was doing just fine, but that he had lost his cow and was wondering if I could help him look for it.  I told him I couldn’t right now because I was helping some people find a wire at the moment, and if I became distracted, we might not only lose the cow, but we might lose the wires as well, so I better just keep on talking so that my friends on the other end can find the wires they are looking for. After that I went to the store and I picked up three cans of peas.  I thought about getting four cans of peas but settled on three and brought them to the checkout counter, and while I was waiting in line I noticed that the little boy in front of me with his mom was looking at me as if he wanted to have one of my cans of peas, so I quickly made it clear to him that I was buying these cans of peas for myself by sliding them further away from him and glaring at him.  Luckily the boy wasn’t persistent otherwise I would have broken down and given him a can of peas because he was looking kind of hungry and I was feeling sorry for him, though, I didn’t want him to know how I was feeling, so I put on a grim expression….”

Needless to say… My monologue went on for another 15 minutes.  Yes… .15 minutes.  I had expected Andy and Diane to have returned earlier, but I didn’t know how hard it was going to be to find the other end of the wires, so I just kept on ramblin’ to the best of my ability.  It’s like what it says in the Bible.  If we wrote down everything I said, it would have filled many volumes.  Being a Disciple of Ramblin’ Ann came in handy that day.  For more about Ramblin’ Ann, you can read the following post:

When Andy and Diane returned they said that they had found the wires right away, but that they had sat there for a while just listening to me ramble.  They said I was cracking them up.  They also mentioned that they thought I was completely crazy.  Well.  I was glad that they found the wires and that my rambling abilities had come in handy.

Cracking a Boiled Egg in the Boiler and Other Days You Wish You Could Take Back

There are some days you wish you could take back after making a grand decision that turns out to look really dumb when your decision fails.  It is important to think outside the box to break new ground as long as you bring common sense along for the ride.  It seemed that during the days when I was a summer help, and even when I was a laborer on Labor Crew that in order to be promoted you had to come up with one grand idea that set you apart from the others and that also failed miserably.

It was said that the electrical supervisor there before Leroy Godfrey (I can see his face, but his name escapes me), was promoted to that position after he caused the destruction of one of the Intake pump motors (a very large pump that can pump 189,000 gallons of water per minute).

To name a couple of minor “Faux Pas” (how do you pluralize that word?  I don’t know), let me start out with the least embarrassing and less dangerous and work my way to the most embarrassing and most dangerous of three different stories of someone thinking out of the box while leaving common sense somewhere behind and maybe wishing they could take back that day.

The first two stories both involve the Electrical Supervisors of two different Power Plants.

Tom Gibson, the Electrical Supervisor from our plant was trying to find a way to keep moisture out of the Bottom Ash Overflow Sump Pumps.  This was a reoccurring problem that required a lot of man hours to repair.  The bell shaped pump would have to be pulled, the motor would have to be disassembled and dried, and new seals would have to be put in the pump to keep it from leaking.

Thus vaporizing the small size 10 wire that is used to wire your house.

All right.  I have given you two relatively harmless stories and now the one about cracking the boiled egg in the boiler.  This happened when I was still a janitor but was loaned to the Labor Crew during outages.  When the boiler would come offline for an outage, the labor crew would go in the boiler and knock down clinkers and shake tubes to clean out clinkers that had built up around the boiler tubes in the intermediate pressure area of the boiler.  Clinkers are a hard buildup of ash that can become like large rocks, and when they fall and hit you on the head, depending on the size, can knock you to the floor, which makes wearing your hardhat a must.  Your hardhat doesn’t help much when the clinkers falling from some 30 feet above hits you on your shoulder, so I always tried to suck my shoulders up under my hardhat (like a turtle pulling in his arms and legs) so that only my arms were left unprotected.  It wasn’t easy looking like a pole with no shoulders, but I tried my best.  I think Fred Crocker the tallest and thinnest person on Labor Crew was the best at this.

This is something that is only done at a Coal-fired Power Plant because Gas Plants don’t create Ash that turns into Clinkers.  Maybe some Soot, I don’t know, but not Ash.  Which brings to mind a minor joke we played on Reginald Deloney one day when he came from a gas plant to work on overhaul.  We were going to work on a Bowl Mill motor first thing, which is down next to the boiler structure in an enclosed area.  We brought our large toolbox and other equipment over to the motor.  Andy Tubbs and Diana Brien were there with Reggie and I.  I think Gary Wehunt was there with us also.  When someone came over the PA system saying, “Stand Clear of Number Two Boiler, We’re Gonna Blast”, all of us dropped everything and ran for the door as if it was an emergency.  Reggie, not knowing what was going on ran like the dickens to get out in time only to find us outside laughing at the surprised look on his face.
