If there were carpenters using Skil saws and such in areas where you could "expect moisture to be present" (vague recall of OSHA language), i.e. framing up a house - no sheathing, no roof, inclement weather / puddles, etc., I could understand personal tools having GFCI, especially when working off a generator or non-protected power source.
But shouldn't the GFCI @ the temp service satisfy the requirement for protection?
Once the house is roofed / sheathed (unless you're a plumber cutting charged water/drainage lines w/power tools, or outside with no GFCI protection at the receptacle), doesn't it constitute a dry space?
