As I understand it CA now requires AFCI protection for practically all residential outlets.
I'm setting up my theater room and it calls for a 50A 220V NEMA 6-50 outlet for the subwoofer I want but I'm having trouble finding an AFCI breaker in this size.
I know this isn't the right place for product recommendations; I guess I'm more fishing to see if there are exceptions I'm missing?
