John,
Sorry I disappered but I was busy last week. I am not the AHJ that requested the #8 go back to the panel, nor do I request the ground rods at hot tubs. I still am surprised at how many EC's ask me these questions. they tell me that the AHJ from XYZ town wants the #8 back to the panel. I asked him the same question I asked here. "Where is it in the code book?" Of course they can't find it but the AHJ required it. I reminded them that the AHJ by code has to cite, chapter and verse where it is written in the code book. Too many AHJ's around here tell the EC, "You look it up." or something like that. I always tell them to take the AHJ to the Const. Board of Appeals. However they don't want to take the time off and lose money. So the bad AHJ wins again.
