I went to a job years ago where they had a fault on the load side of a 4000 amp Bolted Pressure Switch that fed a 4000 amp busway. They had isolated the busway and checked continuity on the busway it showed a dead short and they were in the process of removing the busway when we arrived to see what we could do about getting main service back on line.

I asked to megger the busway and sure enough it was faulted, I then asked to walk the floors to see if there was anything that might be obvious with the busway. All the fused busway switches were off BUT were tapped on the line side for metering.

In another issue we tested the FPE Ground Fault System and it did not function. FPE sent out a factory engineer and he told us they way we tested the GFPE would not work for FPE GFPE's. He said this if front of the EC, the EC's customer and insurance representatives and I was less than happy. I told him then he had 100's to replace as I had tested countless FPE GFPE's the same way and they all worked. He called head quarters talked to their head engineer I talked to the same guy and was told we were right.

Zero Sequence system powered from a temporary source and pass current through the CT.

Sad but true. I can honestly say I've never met someone that I couldn't learn something from them.

Just because somebody has a title, position of authority or a bunch of letters after their name, doesn't mean their right.

I once met the chief electrical engineer in a plant who didn't know how to reverse the direction of a three phase motor.

Very much so, especially when they are the ones that have the say in paying for or sending out warranty parts and equipment.

Met a tech rep out on a new job to troubleshoot on a piece of equipment that we did factory service for. While opening the unit up he was telling me he started with his dad that was an 'old time' electrician. While hooking up to the control system he mentioned his dad would lick his fingers and touch wires to check for voltage. As I turned he tried to showed me just as he got a nice blast.

In one of my first electrical classes we had an instructor who would test for 120V with his fingers. He said they were mostly numb and told us not to try it.

I was on a job the other day where they had a blow-up, customer asked me for advice I gave it to him, later he called me and thanked me for the input but said they would feel better if they hired an electrical engineer to over see the repairs. Today the engineer called me to ask me what I would do about this particular project.

The engineer is a great guy and knowledgeable though has limited experience with this type of work.

This was 208v and I thought he was lucky it wasn't 480v like most jobs with them.

That's a good engineer/person IMO. Humble enough to reach out for help and advice. We electricians and engineers are smarter when we work as a team.

True and on commercial jobs an engineer is usually required to seal the plans, so they don't leak

Had a factory rep to a site, older gentleman that was not familiar with the product he was their to inspect, a 4000 Amp GE HPC. He was there to check why it would not close. I had all ready figured that out (the door safety latch is famous for coming out of adjustment). He attempted to close the switch and did not have enough ass to operate the switch, he said it was too hard to operate as it was defective.

Customer's boss said he condemned it, get me a new one, even though I showed him I could operate the switch. $28,500.00 was my cost for the new HPC.

Some you win and some you win by default
