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.
The issue of a light pole being a structure has not be specifically addressed in the NEC. The was a code change in the 93 or 96 code in 225-32 to address this issue as far as a disconnecting means at a light pole. It seams that some inspectors, based on calling a light pole a structure, were requiring a disconnect at each pole (structure). 225-32 Exception #3 was added to say that a tower or pole used as a lighting standard can have its disconnect located elsewhere. Maybe we need the same type of exception in 250-32. Don(resqcapt19)
Come to find out, the subject of my original Q has been absolutely dissected (in gargantuan proportions)in other BB's, without a final consensus in any of them. It seems like this really needs to be addressed by the CMP, although I don't really know how they would/could reword it. Any ideas?
