Just finished electrical inspection and our one deficiency was that we did not have an arc fault breaker on the smoke detector circuit. Is this really NEC required on a residence? If so could you explain what we are protecting against? I am honestly curious about the logic on this.
Not really a big deal, fast and easy fix, but it seems like electric code is headed toward all GFCI receptacles, all arc fault breakers, and a bubble covers every where in case in rains in the living room.
Thanks for any insight
