    Default Are jumper grounded outlets safe?

    I've seen people run a jumper from the neutral terminal of an outlet to the ground terminal when working in older houses with only two wire systems and no separate ground available. I know it satisfies a tester to read that the outlet is properly grounded and even allows GFCI outlets to work. I also know that in many three wire systems the ground and neutral wires all go back to the same buss in the panel anyway. My normal practice has been to run a new ground wire at least to a cold water pipe or a rod in the ground depending on which is more convenient for the location. Have I been doing a lot of extra work for nothing? Is the jumper arrangement just as safe, and is it an approved (code) procedure?

    Very little can be added to Lloyd's eloquent and definitive answer NO, NO.

    As a side note ground has nothing to do with the function of a GFCI. The GFCI compares the current flow in the hot and neutral and trips if they don't match.

    right .. on the load side, thats what makes it ok to use a gfi where no egc is present, but that sticker doesnt really replace a ground. It really doesnt take much to pull a piece of thhn for an egc.

    Agree. I wasn't saying not to run a ground just correcting a statement made by the op "I know it satisfies a tester to read that the outlet is properly grounded and even allows GFCI outlets to work."

    It might satisfy a tester, but it should not satisfy an inspector.

    Thanks everyone, you confirmed my suspicions. The thing that started me noticing this practice was when someone at a Home Depot sold a customer of mine some outlets he had wired jumpers onto for her. I'm just a general handy man, not a licensed electrician, so I wasn't sure.
