I don't do much old work, so this may sound basic to guys that do this all the time, but: I have a customer that has a few receptacles with no ground in the box. The wire is in great shape, but for some reason, the installer cut off the ground wires back to the sheath of the romex, leaving me with nothing! Argh!
What is the correct way to treat these? I am thinking a GFI w/o a ground will be the safest thing I can do for them. If I put one at the beginning of a run, will it protect all the outlets downstream in this configuration? I would like to run new wire to each, but that may not be possible on a few of them.
Roger, good call on 250.114...looks line I will have to look in to refeeding them a little closer now. These are kitchen counter and fridge receptacles, I would feel better knowing they're grounded, but as we all know, you start a project in a house this old (built ~1914) and the can of worms gets bigger and bigger.
You sure that qualifies as an ungrounded circuit? (Just to play devil's advocate here) To me that's a grounded circuit with poor installation. As you say, the wire's fine, just the installer screwed up. What's to keep you/me/anybody from just cutting off all the grounds and treating the whole house as ungrounded? You sure you won't be assuming his liability when you keep it ungrounded? (and no, I don't have a suggested repair method)
mhulbert. I just finished a house yesterday with the same problem. The person who wired the house the first time cut all the grounding wires. I was able to use the Ideal slices that just push on. You only need about 5/8" of wire. This let me put a tale onto the grounding wire long enough to get to the outlet. My first thought was to use GFCI's like you.
