I finished up a trim of a kitchen on Friday. Tuesday the home owner calls me and says the guys plugged their table saw into an outlet in the garage. The saw started bogging down and finally quit, then the microwave smelled like it was burning and won’t work, compressor in the fridge is out too. After 2 hours of trouble shooting I found a wire with a little insulation blocking the contact screw on the panel. Everything’s working again accept for the appliances. The outlet the guys plugged into was ungrounded 2 prong. I wonder if that had something to do with it.
