Working for some folks who are completely stripping and remodeling a large bathroom. In addition to the usual sconces, recessed lights, shower lights, etc., etc., they are installing a jacuzzi (whirlpool) type tub with two circuits needed - the motor circuit and the heat circuit. No prob there because the original thoughful electricians who wired the house left four unused 15 and 20 amp circuits in the box deadheaded in the attic. But on reading the requirments it recommends adding a #8 solid copper bonding wire run from the tub all the way to the service panel. Thats gonna be a long run and a real pain to fish down an exterior wall to the panel. Any of you guys installed this type of tub with that type of ground ? Any suggestions are appreciated.
