Thanks for your clarifications, Lionel. Clearly, before anyone begins down this path, you have to talk to UL and the 508A contractor to see what is permitted. Yes, the work was done in our plant by the 508A contractor, and the 508A records on this project were inspected by the UL field engineer...
Dan and others with this problem: I dont know why I did not think of this before, but it just occurred to me you may want to sign up with UL for your own 508A certification. I spent a day at a UL seminar for $100 and got all the dope plus free lunch. I did not follow through myself, but I...
Dan: Thanks. I am happy if I can help. As to your questions, all I can say is that UL gives very great freedom and latitude to their 508A certified shops. You should probably start negotiating locally, and you may have to go out of town to find the right contract. Each 508A license holder is...
Thanks for the kind words, Keith. It occurs to me I should have expanded a little more about just how far a UL508A shop is permitted to go. We built in our plant 27 each 237 KW heater controllers. Each was built with a single Motor Control Center bare cabinet, a 600 amp breaker, a 300 amp zero...
The UL versus non-UL question has been answered so many times in the above link, but we all tend to forget how it applies unless we use it every day. Please forgive me if I say something you have heard before:

JTK: Agree, Agree, Agree! "Way Back When" you had to have eight (8) years of certifiable EXPERIENCE to sit for the PE exam. Then along came the ABET colleges and then most states gave four (4) years credit in lieu of experience for the BS from an ABET. So you only needed 4 years of EXPERIENCE...
ASHERENG: Perhaps I did not fully explain why I feel the way I do. I was a Journeyman Electrician for 20 years and got to try to put things together designed by "kids jbarely out of school with PEs" Fun!!!
Now I am a PE with 20 years of field and desk design experience and I have received...
I may be offending someone here, but with over 40 years under my belt, I have to say that...no one should be allowed to be licensed as a PE anywhere until they have at least 5 years of responsible FIELD CONSTRUCTION (hands-on make-build-buy-repair) experience. Too many so called Professional...
