My question is this. If the house is an old 2 wire system with no ground, and if you install GFCI's, will the personnel be protected against electrocution? Example: if a microwave is plugged into a GFI that has no ground and the hot conductor goes to ground on the microwave frame, and the person is touching the cold water faucet in the sink and the frame of the microwave at the same time, will the GFCI trip? in time? I don't think so. So what's the theory behind replacing 2 wire plugs with gfi's? I have an old house that is wired with 2-wire system inside but the service is fairly new and grounded. How can I make the circuits inside the house safe? would GFI breakers work?
