I was recommending a combination arc fault circuit interrupter.
The CAFCI is a new version of the older ACFI breaker. Both trip like a standard circuit breaker when the circuit is overloaded with too much current or there is a short circuit, and the AFCI also trips when there is parallel arcing (hot-to-neutral or an arc to ground) in the protected circuit. Because arcing (you might call it “sparking”) in wiring is one of the the leading causes of house fires, this protection is important.
