Here is a question for someone who knows the code.

I will be installing a generator aboout 60 feet from my home. Could
someone tell me what code requires for grounding it?

Do I put in a grounding rod/rods at the generator site or run its ground
wire to the panel in the house? (It seems that the former could cause a
ground loop and the latter would allow for some potential (voltage) between
the generator and the adjacent earth.)

Thanks.
