Thanks to those who helped me earlier. A few outlets in my new condo do not have ground wires (most do). I've run into another odd outlet and have a question. Outlet is in kitchen next to sink. I want to put in a GFI. I take the old outlet out and it has no ground, 2 black wires and 1 white wire. Which is odd because my circuit tester said it had a properly functioning ground. The screw for the old outlet is very long and it's possible it is touching a copper wire that is back there (this copper wire is where the ground wires in the outlets that have them are connected). I put the old outlet back in and stepped away from this outlet to think the problem out. I imagine that if I use the same long screws I should still touch the copper wire in the back and have a functioning ground. But will a GFI work without the second white wire? Just a tad confused. On the upside I've only got a couple more outlets/jacks to worry about before I'm finished. All that's left then is a sconce and a chandelier and then it's time to move furniture in.
