Hi y'all. Long time lurker. First time posting on the electrical forum. So I've come across a strange one today. I have 3 bathrooms and one half bath all in one 20A circuit. Never had a problem till now. 1977 house. In one bathroom (that was a 2009 addition) all power is now out (bank of 4 led ceiling lights, vent fan and a gfci by the sink) are all without power. No other outlets in this bathroom. The other bathrooms are fine so it's not the 20A breaker. I read the sticky above. No odd gfci's in some other place that could have tripped. The gfci in the dead bathroom will not reset. No power to it. I don't recall if that gfci kills power to the overhead lights and fans or not. (Is that normal or abnormal to do that) I pulled the light and fan switch cover (it's a near new dimmer switch for the light bank, and a separate older switch for the vent fan) and checked for loose wires. All are secure on screws And/or wire nuts. I have not pulled the GFCI to check it (not really sure what I'd be looking for other than obvious disconnected wires). Only other bit of info I can think of that may be relevant is we have heard a mouse about the house in this area. Trying to catch it. Perhaps he chewed through some wires? Can a mouse chew through solid copper? What steps should I follow now to logically troubleshoot this. I do have a multimeter and basic electrician tools.

Hello, My husband and I are remodeling a bathroom in our basement. I marked all of the wires(except for those I didn't disconnect) but I have a problem and need help. Here is what I have. switch(sw1) 1 has 14-2 coming from the light fixture and 14-2 coming from switch 2(sw2) . I am not sure which is the light fixture or sw2 however the wires on sw1 are as follows. I have a white and a black on the top terminals and a black on the common terminal with the remaining white pig tailed with other whites in the box. Sw2 has 14-2 wire only with one black, one white wire, and a ground. I don't see a power source to either switch1 or light fixture so I'm guessing the power source must have been on sw2. Any idea how to get this to work again?
