A tester indicated that receptacles were properly wired with a "ground"...outside there was a ground rod with #14 stranded wire running to the receptacle box. In another part of the home there was another ground rod with a stranded #14 wire going to the receptacle box. I checked the resistance from white common to the prong connected to the ground rod and read 63 ohms. This install provides a path to ground, but with some resistance which would probably not divert power away from a person being shocked, nor trip the breaker? Connecting it to copper plumbing which would be connected to the System Ground Plate would ensure less resistance and more chance of tripping a breaker? Is installing a three prong receptacle connected to a ground rod separate from the incoming service someone's creative way to provide a path to ground unacceptable, and if it is ok would it require connecting all ground rods together??
