Greetings all. This is my first post by the way. I am a novice when it comes to wiring, so I thought it would be a good idea to do some reading, on-line research as well as to seek out some knowledgeable people in the field of home electricity DIY. Here is my situation. I have an older home, built back in the 50's. The outlets , according to my circuit tester, have an "open ground" . I want to be able to protect my home electronics, particularly my office computer. No, I have been told that a power bar with a circuit breaker will be of no use in the even of a power surge, as the power can't be shunted through the ground .. So ... will a GFCI be of any use in this scenario? Is there a way to ground the outlet somehow, without doing major re-wiring. Any assistance will be greatly appreciated
