25 year old home, owned it for 10 years now. Yesterday one bathroom outlet stopped working (not a GFCI outlet). What I know so far: Looked at breaker box, was not tripped. Opened the outlet up and found both hot and neutral wires had melted sheathing (there was no evidence of arcing/burning). Other outlets on same circuit were also out. Checked voltage on the breaker itself - was fine and had 120VAC coming out of the breaker. I am not aware of any GFCI on this circuit, but I need to verify all outlets. If there is no GFCI on this circuit, what else could it be? is it possible that one of the other outlets has a wire that completely came off? Thanks in advance for any advice!
