:jester: Sorry i posted this to and old thread earlier by mistake but I have a situation where there is a open ground somewhere and all 4 outlets in a back bedroom are not grounded so i check all of them and cant see a problem so I put in a GFI outlet on the first one - I think anyway and it wont trip with my tester but where the gfi outlet is a privous H/O punched thru the wall to exterior to add an outside out let and its about 4feet to the metal water main So i ran a piece of wire over to it and clamp it on and pigtailed it to the existing ground and the GFI works and protecting all the other three outlets ? my question is would that be exceptable? and the outside outlet is in a metal switch box for exterior use can i simple drill a hole thru it and run the wire out to the water main and clamp it ? and what size copper wire would work ? its on a 15 amp circuit with 14 gauge wire now ?
