The electricians will be using a temporary generator (mounted on a trailer outside the building) to supply a MCC while some work is done on the MCC's normal feed.
The MCC is a 3 wire MCC (no neutral) so they won't run a neutral wire from the generator to the MCC.
So the question of grounding came up. Specifically, do we need to run a ground wire from the generator to the MCC? And, do we need a grounding electrode at the generator?
I think the answer is yes to the ground wire, and yes to the electrode.
But I wanted to ask what all the experts here think. Are they required??
