A neighbor wants to put a 60A subpanel in his detached garage, about 30' from the house. He's doing it himself, has already run a UG 1" conduit with 3 #4, & a #8 EGC.
AHJ said he's required to install another grounding electrode @ the garage, but why?? I don't have a good answer for him.
His reasoning is that if the sub was on the fence, 30' further, it wouldn't be required. I can't argue with that.
