How to Properly Test a GFCI Outlet: A Step-by-Step Guide


This guide will explain how to properly test your home’s Ground-Fault Circuit Interrupter (GFCI) outlets. GFCIs are critical in electrical safety, protecting you from potentially life-threatening electric shocks. Regular testing ensures they function as intended. In this guide, we’ll walk you through the testing process.

Testing Your GFCI Outlet Manually:

  1. Locate the TEST Button: Find the TEST button on your GFCI outlet. It’s typically labeled and may be red or black.
  2. Press the TEST Button: Firmly press the TEST button. You should hear a distinct click as the GFCI trips, disconnecting power.
  3. Verify Power Cut-off: To confirm the GFCI has cut off power, plug in a lamp or another device. The device should remain off, indicating that power has been successfully disconnected.
  4. Press RESET: Finally, press the RESET button to restore power to the outlet.

If the TEST button fails to trip the circuit or the outlet remains energized after pressing TEST, replace the outlet immediately.

Using a GFCI Tester:

Alternatively, a handy GFCI outlet tester can check GFCI functionality and identify wiring issues. Here’s how to use it:

  1. Plug in the Tester: Insert the GFCI tester into the outlet.
  2. Use the Tester’s Test Button: Press the tester’s built-in test button to trip the GFCI, mimicking the TEST button on the outlet.

By following these testing procedures, you can ensure your GFCI outlets operate correctly, safeguarding your home against electrical hazards.

Seek Professional Assistance:

While regular GFCI testing is crucial, electrical systems in your home can be complex. If you encounter issues beyond the GFCI outlet or need help with wiring problems, it’s wise to consult a certified electrician.

Certified electricians possess the expertise to diagnose and address a wide range of electrical issues, ensuring the safety and functionality of your home’s electrical system. Whether you’re facing outlet problems, circuit disruptions, or other electrical concerns, professional assistance can prevent potential hazards and ensure your electrical needs are met safely and efficiently.


Regularly testing your GFCI outlets is a simple yet essential task to maintain electrical safety in your home. When in doubt, consult a qualified electrician for any electrical work. Safety should always come first.
