How to Install GFCI Receptacle Outlets (DIY)

Introduction

Installing a GFCI outlet doesn't have to be confusing. Follow these steps and photos to install a GFCI without getting line and load connections confused.

GFCI outlets reduce the danger of deadly shock from faulty plug-in cords and devices. A GFCI (ground fault circuit interrupter) is a special type of outlet that detects dangerous ground faults and immediately turns off the power to stop shocks. You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit.

While it’s common to find GFCI outlets in bathrooms and kitchens, there are GFCI outlet requirements. The electrical code also requires GFCIs in unfinished basements, garages, most outdoor receptacles and places where construction activity occurs. We’ll show you how to replace a standard duplex receptacle with a GFCI and wire it to protect other outlets. (For more information about wiring outlets, see Wiring Switches and Outlets).
