How to Run & Connect GFCI Switches

Wiring a combination switch/GFCI outlet provides two devices with power.

A ground fault circuit interrupt, or GFCI, outlet and switch combination provides two devices in one package. GFCI's are required in bathrooms, kitchens and all exterior outlets. These devices monitor the current in the hot and neutral wires. If an imbalance is detected, the power to the circuit is turned off, minimizing the chance of electrocution. Correctly wiring a GFCI ensures proper operation.

Things You'll Need

• Non-contact voltage detector
• Switch/GFCI outlet combination
• Wire strippers
• Screwdriver
• Pliers
• Twist-on wire connectors

Instructions

1. Turn off the power at the home's distribution panel for the circuit you are working on. Confirm the power is off by touching a non-contact voltage detector to the wire's insulation.

2. Remove the existing outlet by removing the screws that fasten it to the electrical box. The electrical box is the metal box that is fastened to the home's wall system. Loosen the terminals on the outlet and disconnect the wires.

3. Strip 3/8 inches of insulation off the three conductors coming from the distribution panel with wire strippers.

4. Loosen the terminals on the combination outlet/switch. Wrap the black wire from the distribution panel around the brass or hot terminal and tighten it down. Wrap the white wire from the distribution panel around the silver or neutral terminal and tighten it down. Wrap the green wire around the ground terminal and tighten it down.

5. Strip 3/8 inches of insulation off the three wires coming from the light. Loosen the grounding screw on the electrical box and wrap the green wire around this terminal. Tighten the terminal down.

6. Twist the black wire coming from the light with one of the black wires on the back of the switch. Install a twist-on wire connector on top.

7. Twist the white wire coming from the light with the other black wire on the back of the switch. Install a twist-on wire connector on top.

Tips & Warnings

• Electrical modifications made in your home should be inspected by your local building authority.

• Double-check that the power is off before beginning any work.
