I have an intermitten problem with half of the outlets not working in my master bed. I have had several electricians out and they have thightened all the wires, switches and plugs in the bedroom and circuit panel. The problem still happens, one day all the plugs work, the next half orf the room is dead, then they come back on magically. Both electricians see no eveidence of arching or any code violations with the wireing but a puzzled. Could this be a failing circuit breaker?? This is the only thing we have not yet changed. By the way, the breaker itself has never triped. Look forward to your response.
