Functions: AFCI Receptacle Vs AFCI Breaker
Arc-Fault Circuit Interrupter (AFCI) receptacle is intended to be installed as the first outlet in a branch circuit. It provides protection to downstream and upstream branch-circuit wiring, cord sets and power supply cords against the unwanted effects of arcing.
AFCI breakers are intended to protect downstream branch-circuit wiring and cord sets, as well as power supply cords.
Receptacles are a less expensive, code-approved alternative to AFCI breakers.
Locations & Requirements
All 120volt, 15 and 20amp branch circuits supplying outlets installed in kitchens, living rooms, dining rooms, libraries, dens, bedrooms, closets, hallways, laundry areas or similar rooms shall be protected by AFCI.
New construction requires extended or modified branch circuits to be protected by AFCI. Receptacles that require replacement overtime, need to be replaced with AFCI receptacles. AFCI/GFCI combination receptacles requirements may vary by location/city.
Testing your AFCI Device
AFCI receptacles are designed to be tested on a monthly basis. To test the AFCI, you must press the “Test” button and make sure the power is off. Then you must press on the “Reset” button and make sure the power is back on. If neither button works, the device must be replaced.
AFCI breakers have a similar test function. To test an AFCI breaker, you must press the “Test” button and make sure the breaker trips. If the breaker successfully trips, you will see the switch move to a middle position between the ON and OFF position. Then you must move the switch to the OFF position before moving to the ON position (The breaker will not allow you to move the switch from the middle position to the ON position. You must go from the middle, to the OFF position, then to the ON position to ensure it successfully turned back on). If it trips again when moving the switch to the ON position, contact a licensed and insured master electrician to determine the problem.
