Is your shop UL listed for building control panels?
Some of the inspectors around here will make you tear it out if it doesn't have that UL sticker.
Yes I know, Apparently this job it wont be a issue, but the other work that the client has is required to done by a UL shop. And Im not sure what it takes to achieve that.
For the life of me, by using UL approved compents inside, a UL enclosure, and wiring according to NEC and fully engineered dwgs to boot.......Ah dont get me started on UL listings.....I just dont get it....
If you buy a PLC off the shelf, what are you going to install it in? DUH a box, what kind? A Hoffman? How big? enough to provide ample wire bending radius, etc. How are you going to make your field terminations? DUH Din rail and terminals sized for the circuit.......makes my blood red ,,,,,UL, It's a racket IMO.....
Its like me buying a little 120v air conditioner at Lowes last summer. It has a GFI protected cord that is a molded assembly. BIG STICKER says....WARNING, THIS IS A UL APPROVED ASSEMBLY, IF THIS CORD FAILS, IT MUST BE RETURNED TO THE FACTORY FOR REPLACEMENT,DO NOT REPLACE THE CORD.....YEA like that's going to happen....
