UPS == Uninterruptible Power Supply

APC makes a lot of them. You can get one for around $40. Its basically a surge protector with a battery in it. Since you won't be using a ground it will protect from surge through the outlet, even though it is supposed to trip immediately in case it doesn't you have something to protect your electronics. A grounded outlet gives that surge another path to escape but since it isn't grounded it will surge straight through anything hooked to the outlet.

You can get a straight surge protector but UPS is the way to go in my opinion. A lot of them(all of them might I don't know for sure) ground themselves inside of the UPS housing which doesn't give you a true ground but it still is better than nothing for protecting your electronics.

So at least have a decent surge protector if nothing else.

A GFI or a GFCI does not need require a ground. A GFCI measures any current difference between the live and neutral wires. If they don't match then the current is going somewhere it isn't supposed to and it trips. It doesn't require a ground to do that.

Some request a ground some have intructions for not using a ground. I would install one of these in place of the current outlet and install a UPS with a battery because they ground themselves inside of the UPS housing.

Edit: a little more explanation, the ground wire is a path for electrical current to return to the ground in case of a short which in the event of a short circuit it would cause the fuse to blow or breaker to trip. The GFCI will measure currents for the only 2 wires you have and if it suspects a short circuit by a voltage surge etc then it will trip anyway preventing shock or damage to you or your electronics.

But like I said use a UPS Batter backup to protect you electronics. I recommend this on a grounded outlet as well.




I was under the impression that you couldn't hook up a GFCI without the ground. However, now that you've mentioned this, I looked around on google and have found that you are correct, although it does seem to be a contentious issue.

I can hook up a new outlet no problem. Will go to homedepot tomorrow and let you know how it goes.

What is the UPS batter backup, by the way?

Thanks so much for the discussion everyone!


  There you go.  A length of Romex wire and an outlet and box arent that hard to install.  I ran a few of them in my basement.
