The 8 pages that link to Arc-fault circuit interrupter, each with the reason it gives.

• Circuit breakerCompared with: Its arc detection targets hazardous arcing that may not draw enough current to trip an ordinary breaker.

• Short circuitRelated: Some short-circuit damage produces arcing that conventional overcurrent protection may not detect promptly.

• Ground-fault circuit interrupterCompared with: An AFCI targets arcing faults, while a GFCI responds to current escaping the intended path.

• Residual-current deviceCompared with: Arc faults can be dangerous without producing the live-neutral imbalance that trips an RCD.

• Overcurrent protectionCompared with: Arc faults can be hazardous without producing enough current to trip standard overcurrent devices.

• Electrical faultBroader topic: It targets dangerous arcs that ordinary overcurrent protection may not detect promptly.

• Distribution boardRelated: Some boards use these devices to protect branch circuits against fire-starting arcs.

• Earth-leakage circuit breakerCompared with: It targets hazardous arcs that may not create enough leakage to trip earth-leakage protection.
