How to Install a GFCI Outlet, AFCI and Dual AFCI/GFCI Outlet

Ground Fault Circuit Interrupter (GFCI) outlets, Arc Fault Circuit Interrupter (AFCI) outlets, and Dual-Function AFCI/GFCI outlets provide important electrical safety protection for modern homes. This installation guide and video explain how to replace a standard receptacle and properly install a Leviton SmartlockPro® protection device while following manufacturer instructions and applicable electrical codes.

A GFCI outlet helps protect people from electrical shock by monitoring current flow between the hot and neutral conductors. If the device detects a current imbalance, it quickly interrupts power to reduce the risk of injury.

An AFCI outlet helps reduce the risk of electrical fires by detecting dangerous arc-fault conditions within a circuit. AFCI protection is commonly required in living spaces such as bedrooms, family rooms, hallways, and similar locations.

Dual-function AFCI/GFCI outlets combine both arc-fault and ground-fault protection within a single device, providing enhanced safety and code compliance for many residential applications.
