How to Install Ground Fault Circuit Interrupter (GFCI) Outlets

Safety First

Before beginning any electrical work, ensure your safety by turning off the power to the outlet you’re working on at the electrical panel. Double-check the circuit with a tester to confirm it’s off. If you’re uncomfortable working with electricity, consult a professional electrician.

What You’ll Need

Equipment / Tools:

Flat-head screwdriver
Phillips-head screwdriver
Circuit tester
Pen or pencil

Materials:

Tape
New GFCI outlet

Step-by-Step Instructions

1. Turn Off the Power

Locate the electrical panel and turn off the circuit breaker for the outlet you’ll be working on. If the panel is unmarked, turn off the main breaker.

2. Check the Circuit

Use a circuit tester to confirm the circuit is off.

3. Remove the Outlet and Mark Each Wire

Unscrew the outlet cover and gently pull the outlet out of the wall. Note the location and color of each wire connected to the old outlet. Use tape and a pen to label each wire accordingly.

4. Reattach the Wires

Connect the wires to the new GFCI outlet as follows:

Hot wire (usually black or red) to the brass terminal
Neutral wire (usually white) to the silver screw
Ground wire (bare or green) to the green screw

Wrap the entire side of the outlet with electrical tape to prevent any screws from touching the box or stray wires.

5. Install the Outlet

Push the outlet back into the electrical box and secure it with screws. Install the cover plate.

6. Turn on the Power and Test

Restore power at the electrical panel. Press the reset button on the new GFCI outlet. Check the circuit with a tester or use a small appliance to ensure power is restored.

Troubleshooting

If the new outlet doesn’t work or the reset button keeps popping out, consider the following:

Faulty outlet: Replace the outlet.
Wiring issues: Check the wiring connections and consult an electrician if necessary.
Electrical overload: Reset the circuit breaker or unplug unnecessary appliances.
Damaged wiring: Call an electrician for professional repairs.

When to Call a Professional

Seek professional help if:

The new outlet fails to work.
The reset button on the outlet frequently pops out.
You’re uncomfortable working with electricity.

Regular Maintenance

Test your GFCI outlets every three months by pressing the test button. If the reset button pops out, replace the outlet.
