What Rooms Require Afci Protection According to the 2026 Nec?

According to the National Electrical Code (NEC) 210.12, arc-fault circuit interrupter (AFCI) protection is mandatory for all 120-volt, single-phase, 15- and 20-ampere branch circuits that supply outlets in a wide variety of rooms within a home. The requirements have expanded significantly since they first appeared in 1999 and now include:

• Kitchens and Dining Rooms
• Bedrooms and Living Rooms
• Family Rooms and Recreation Rooms
• Sunrooms, Hallways, and Closets
• Laundry Areas
• Similar rooms or areas

These standards are designed to detect dangerous electrical arcing—sparks within your wiring that can reach temperatures of 10,000°F—and cut off power before a fire can start. Because these safety standards are updated every three years and local jurisdictions in California and Texas may adopt specific amendments, local code always takes precedence.

We position these breakers directly on the electrical service conductors inside your panel to provide code-compliant protection at the source.
