I live in a house built in 1955. The outlets and switches in the house are not grounded, the 2 prong types. How do I go about installing new outlets and switches that are grounded?
Thanks

In my opinion to do it right it requires the rewiring of the whole house. Circuit by circuit. As your wiring is probably old and brittle. I would first look at your Service Panel. Is it fuses or breakers?If fuses change your service panel. If it is breakers, then I would figure out your load per circuit. Such as how many fixtures are on a circuit, how many outlets, so on. This will determine your wire size and breaker size. This is actually a pretty in depth thing to take on by yourself and I would suggest hiring or getting a buddy that is a licensed electrician to help you figure correct sizes. Then you have to look at whether the walls are going to allow you to pull new wire or have to snake them through insulation. Just take a hard look at it. I am doing the exact thing with a house I just purchased that was built in 1945. I found it is easiest to do a room at a time and remodel the room as I go. Strip the walls and then wire room and then finish room. Expensive but I was remodeling the whole house anyway. Just some suggestions. Good Luck and hope it goes good for you.

Thanks for the response.

It is breakers. I wanted to see what the process was. Its going to be tough to rewire, not much attic space to work with. Is that the only option I have?

Looks like I'm in the same boat with you guys. Old house, lousy wiring, no attic space. I decided to go the whole route: New 200A service entrance and all new wiring.
As long as I have to do this anyway, I plan to use EMT and oversize all the wiring.
This may sound crazy, but it appears I'll actually have to remove the roof to do the attic wiring. Good/bad news - the roof needs replacement anyway.

Well you can disconnect power to the circuits one at a time and try to pull new wire in by attaching to the old wire at one end and then pull from the other end. Unfortunately this usually tends to be impossible as the old wires are usually stapled down. You can also try a snake to feed down through wall, but if you are going to do the whole house I suggest doing it room by room and remodel as you go. Less chance of tearing the jacket or nicking a wire by trying to pull it through when you can't see its path. Just my thoughts. Hope it goes good what ever you decide to do.

If you don't actually need a ground such as for a surge suppressor, you can replace the receptacles with GFCI and label ungrounded. One GFCI in the first receptacle can protect the other down the same line.
