What is the minimum requirement for AFCI protection in residential applications?

For residential applications, the minimum requirement for Arc Fault Circuit Interrupter (AFCI) protection specifically pertains to circuits serving bedroom areas. AFCI breakers are designed to protect against arc faults, which can lead to electrical fires due to damaged wires or loose connections. Since bedrooms often contain a variety of electrical devices and are places where people sleep, ensuring these circuits are protected by AFCI devices is crucial for enhancing safety against potential fire hazards.

While other areas of the home may contain electrical outlets and devices, the National Electrical Code (NEC) emphasizes bedroom circuits for AFCI protection as a primary focus. This requirement evolved due to a growing awareness of the risks associated with arc faults, especially in sleeping areas, and the concern for residential fire safety. As such, while living rooms, kitchens, and other circuits can benefit from AFCI protection, the specific minimum standard set forth underscores the importance of protecting bedroom circuits.
