    Thanks for the heads-up, I just didn't understand exactly how breakers work, but now I do.

    Does anyone know if arc fault breakers will work with ceiling fans? I was reading that they don't work with electric motors such as treadmills, or dishwashers.

    Many motors have brushes in them, and those will cause some arcs. I think they'd be problematic on an arc-fault breaker.

    You want to make sure that you do not have Federal Pacific Electric (FPE) breakers and panel. A high % do not trip when they should; they also have other well documented problems. Serious stuff. Please take the 60 seconds to look at the panel.
