Hello,
New member here. Our Company is an OEM for the water/wastewater industry. We also design and build our own control Systems and panels. Our panel shop is UL-508A approved.
I?m not sure if this is the right forum but I have an ongoing issue with our shop foreman regarding the service ground lug of control panels. He currently taps and bolts the ground lug right on the painted back panel (next to the service main breaker). I finally noticed he doesn?t (and learned he never has) scraped or grinds the paint off the back panel prior. To me it seems like common sense which is why I never took notice.
I am looking for documentation in the NEC and/or UL that is specific to control panel grounding. I do see some articles referencing the NEC 250-96 but this seems to be regarding conduit grounding and not necessarily industrial control panel service power grounding.
Any help on this would be greatly appreciated.
Thanks!
Steve
