Can I use any brand of circuit breaker in my panel?

No, breakers must be specifically listed for your panel brand. Using incompatible breakers is a code violation and safety hazard. Check your panel label for approved breaker types.

What is an AFCI breaker?

An Arc-Fault Circuit Interrupter detects dangerous electrical arcing that could cause fires. NEC requires AFCI protection in bedrooms, living rooms, and most habitable areas in new construction.
