In my 14 year old residence, the bathroom outlets on the second floor no longer have power. These outlets are fed by one 15 amp leg of a double breaker. At the breaker output I can measure 120v. When I switched this breaker with another breaker in my service panel, the problem does not follow the breaker. The wiring is all internal to the structure and I do not believe it traverses the attic. When I measure between the hot side of all of the outlets where a plug would be inserted and ground I read zero voltage. I inspected the outlets and the wiring appears to be solidly screwed down.
