I have a two-pole arc fault breaker that is on its own. It’s used for a bedroom with one circuit used for a plug in wall heater. The other circuit is for the remaining outlets and lights in the room.
I get intermittent tripping of the arch fault breaker when the garbage disposal, which is on a completely different circuit, is on or an electric saw is plugged into an exterior outlet. Why would a separate circuit trip the arc fault?
My solution was to put both bedroom circuits under a single pole arch fault breaker. Did I not use the two pole arc fault breaker correctly?
