probably better suited in a Industrial Panel Forum somewhere, but I'll try here first...
Small Steel Industrial Panel/Enclosure - incoming power is 120V. Power cord enters thru gland into box.
Ground wire should go where?
At the moment - it is going to a terminal block. The DIN-rail mounted finger safe type. From there, more green wires emanate and land at various power supplies, etc.
(This is not about the number or style of terminal blocks - let's assume that's all in order.)
Should that FIRST green wire - the one right from the wall - be landed at a stud or hard bonded terminal of some type? Or is this "terminal block" distribution method OK?
I cannot find anything (NFPA79, for instance) that gives clear guidance on this, but I am notoriously awful at interpreting their verbiage - so maybe it's clear...somewhere...
Thanks - Input anyone?
