Hello. I just purchased a UPS and the light on the back which says building wiring fault is lit. Power works correctly and everything seems fine. I opened the outlet and saw 2 wires coming into the metal box, each with 2 wires (black and white). Nothing was connected to the ground so Im thinking the problem is probably due to lack of ground? I searched around on the internet for a simple fix, and some said that if the box was grounded then you just run a wire to the back of the box. The cables coming into the box look like snakeskin with paper insulation inside and its very thick and solid. Its in great shape for wires put in place in the 1950's. It feels almost like metal, but its not. And so it probably cant be used as a conductor of electricity to use for ground. Im looking for a quick fix here. I was reading about GFCI outlets but those appear to not be appropriate for surges as you still need a true ground.
Is there any device that one could buy to create the same effect as a ground connection? I dont want to hire an electrician spending big bucks to fix this problem as I only really need it for one outlet. Cold water pipe isnt available near the area, only a hot water baseboard heating pipe, but thats not appropriate for ground.
Were 3 prong outlets allowed to be installed with no ground under any electrical codes in the past? Im assuming that whoever bought the house originally replaced the outlets but never added the grounds.
So anyways, its either I live with the problem of lack of true ground or find some way that wont require hiring an electrician to ground the outlet. I can install outlets if the wiring is in place, or connect wires to the outlet box, but cant do the rest. Just for safety sake because of lack of ground I may put in the GFCI outlet if I cant get a true ground so at least Ill have something.
Any suggestions here?
Thanks.
