AFCI (Arc Fault Circuit Interrupter) and CAFCI (Combination Arc Fault Circuit Interrupter) circuit breakers both protect against electrical fires caused by arcing faults. AFCIs detect parallel arcing faults, while CAFCIs detect both parallel and series arcing faults. These breakers help prevent fires by quickly shutting off power when they detect dangerous electrical arcs, reducing the risk of fire in residential buildings.

What are the key differences between an AFCI breaker and a GFCI, and which one is more suitable for protecting against electrical hazards in a residential setting?

The key difference between an AFCI breaker and a GFCI is the type of electrical hazards they protect against. AFCI breakers protect against arc faults, which can cause fires, while GFCIs protect against ground faults, which can cause electric shocks. In a residential setting, both AFCI and GFCI breakers are important for safety, but AFCI breakers are more suitable for protecting against electrical hazards that can lead to fires.
