I'm preparing my mother's home for sale. It was built about 1953 and the wiring lacks the usual third ground conductor. To make it possible to conveniently plug in stoves, refrigerators, and power tools with three-wire cords, my father simply replaced two-wire outlets with three-wire ones, leaving their ground lugs disconnected.
At this point, every switch and outlet in the house is worn out, paint-covered, or installed up-side-down, so I plan to replace all of them. I started out intending to turn the clock back and replace all the outlets with two-wire ones, but it appears that I can't even buy them any more. Certainly the local HD doesn't have any.
So the question is whether there's a proper way to connect a three-wire outlet to antiquated two-wire cable?
