Good Morning Everyone,
I have a question regarding panel labeling requirements. We are working with a new industrial electrical contractor on a couple of new machine installs. The contractor is insisting that the distribution panels do not require proper labeling of any form as outlined in NEC 408.4 (A). They are maintaining that since the panel and breaker #s are being field labeled at the machine or connecting junction, the NEC 408.4(A) provisions no longer apply. I am not a code expert by any means, but I can't locate a single code reference that would grant such an exclusion. It just seem this would have significant inherent safety risks associated with this approach.
Can anyone confirm if such an exclusion actually exists? I just want to do our due diligence to maintain our current building wide code compliance when this installation is finished.
Thank you for your time.
