Installed new bath exhaust fans yesterday. First one was fine. Second one (identical) not so much. I turned the power back on and the fan and lights came on as normal, but when trying to turn the fan off, the breaker pops.
(There was a fan there before; this is a replacement - it was wimpy, but caused no electrical problems) I seemed to hear a sound from the actual wall switch as well as the breaker popping - I thought it might be arcing - a very old switch, so I swapped it out. Same problem.
I disconnected the wiring harness on the fan for now, so I can still have lights in the bathroom till I figure this out. There was a fan already in this location, and I doubt this one has a much higher electrical draw - not so much higher as to pop a breaker. I plug some high draw things into this circuit (hair dryer, etc) and there is no problem. Maybe I am looking at a problem with the fan itself?
