Arc-fault circuit interrupters (AFCIs) help protect against electrical fires caused by dangerous arcing.
AFCI protection and GFCI protection serve different purposes: AFCIs address arcing-related fire hazards, while GFCIs help protect people from severe electrical shock.
AFCIs need testing after installation and every month to confirm that they trip as intended.
Test your AFCIs monthly using their TEST button and the manufacturer’s instructions. Plan for the brief loss of power to connected devices.
If an AFCI does not trip during its test, contact a licensed electrician to have it replaced.
Ask a licensed electrician about your home’s AFCI protection. Have a qualified professional handle AFCI installation or replacement.
