- Arc-fault circuit interrupter - Wikipedia
AFCIs are devices designed to protect against fires caused by arcing faults in the home electrical wiring The AFCI circuitry continuously monitors the current and discriminates between normal and unwanted arcing conditions
- What is an AFCI | AFCI Safety
An AFCI is a product that is designed to detect a wide range of arcing electrical faults to help reduce the electrical system from being an ignition source of a fire
- AFCI (Arc Fault Circuit Interrupter) - How Does it Work?
AFCI stands for Arc Fault Circuit Interrupter (aka AFDD = arc-fault detection device) It is a protective device used for protection against fire hazards caused by arc faults

- How to Determine When to Use Arc Fault Circuit Interrupters
AFCI standards were introduced in the 1999 NEC (National Electrical Code) and are required in new dwelling construction and when installing, extending or updating new circuits in an existing dwelling, or when replacing receptacles located in designated locations
- The Role of AFCI and GFCI Protection in Home Safety
Purpose: AFCIs are designed to prevent electrical fires caused by arc faults An arc fault occurs when there is an unintended electrical discharge (arc) between conductors, which can lead to overheating, sparks, and fires This can happen due to damaged wiring, frayed cords, or faulty connections
- 2019 CALIFORNIA ELECTRICAL CODE AFCI REQUIREMENTS IN DWELLINGS
New wiring for hard-wired smoke and CO alarms is required to have AFCI protection, which can only be supplied by a circuit breaker (R314 6) If the existing electrical panel is a type that does not accept AFCIs, it must be replaced or be supplemented with a subpanel
