Well, you are fortunate indeed! We recently purchased this home and we had a problem when we used the microwave, the breaker would trip, so I checked the outlet out and it was fine. its a 1969 home, so did not really understand. We moved the microwave and it happened again. This time when I turned the breaker back on, it tripped again, twice in a row, so I left the power off and pulled the outlet out. One of its hot screws were loose and the wire had touched the ground screw, arking and welding everything together. Worste part was, it was in a metal outlet box, wich it all got welded to. So I had to use a big screw driver to break it all apart and fix!! So we were lucky. That was durring the day! You were fortunate for the smoke detectors to wake you up sincethe GFI did not apparently work properly either! Jody
