Home Tips Issue #2 - Test Your GFCI's

This issue we’re going to take on a fairly simple yet extremely important home maintenance task. Testing your GFCI plugs.

GFCI Testing

A Ground Fault Circuit Interrupter (GFCI) plug is designed to protect people from getting electrocuted and prevent some types of fires by monitoring the electrical current flowing through a circuit.

See the stats on the Electrical Safety Foundation site.

The Risk

• Increased Risk of Electrical Shock: A failed GFCI will not be able to detect ground faults or interruptions in the current flow, which means it will not shut off power in dangerous situations. This significantly increases the risk of electrocution.

• Higher Likelihood of Electrical Fires: Without the protective function of a working GFCI, ground faults can go undetected, potentially causing overheating and electrical fires.

How to Test a GFCI Outlet with a GFCI Tester

Using a GFCI tester is a reliable and straightforward way to ensure your GFCI (Ground Fault Circuit Interrupter) outlets are functioning correctly. Follow these steps:

Materials Needed:

• GFCI tester (available at Amazon and most hardware stores)

Step-by-Step Instructions:

1. Locate the GFCI Outlet:

   • Identify the GFCI outlets in your home. They are typically found in bathrooms, kitchens, garages, and outdoor areas. Sometimes multiple plugs are connected to 1 GFCI.

2. Prepare the GFCI Tester:

   • Familiarize yourself with the GFCI tester's indicators and instructions. Most testers have lights or indicators that show the status of the outlet.

3. Plug in the GFCI Tester:

   • Insert the GFCI tester into the GFCI outlet you want to test.

4. Check the Initial Indicator:

   • Look at the tester's lights or display. It should show that the outlet is wired correctly before testing the GFCI function. Refer to the tester's instructions for interpretation.

5. Test the GFCI Function:

   • Press the test button on the GFCI tester. This should simulate a ground fault and cause the GFCI outlet to trip, cutting off power.

6. Verify the GFCI Trip:

   • Check that the tester's lights or display indicate that the power has been cut off. If the tester has no power, it means the GFCI has tripped successfully.

7. Reset the GFCI:

   • Press the "Reset" button on the GFCI outlet. This should restore power to the outlet.

8. Confirm Functionality:

   • The GFCI tester should show that the outlet has power again and is wired correctly. If everything is in order, the GFCI outlet is functioning properly.

Tips & Tricks

• Regular Testing Schedule:

  • Tip: Set a regular schedule to test your GFCI outlets. Monthly testing is recommended to ensure ongoing safety.

  • Trick: Add a reminder to your calendar or set an alarm on your phone to test your GFCI outlets at the same time each month.

• Use a GFCI Tester for Accuracy:

  • Tip: While the built-in test button on a GFCI outlet is useful, using a dedicated GFCI tester can provide more accurate results.

  • Trick: Invest in a good-quality GFCI tester from a reputable brand, and keep it in a designated place so it’s always easy to find.

• Test All GFCI Outlets:

  • Tip: Don't forget to test all GFCI outlets in your home, including those in less frequently used areas like the garage, basement, and outdoor spaces.

  • Trick: Make a checklist of all the GFCI outlets in your home and check them off as you test each one to ensure you don’t miss any.

• Inspect for Physical Damage:

  • Tip: While testing the functionality of your GFCI outlets, also inspect them for any physical damage, such as cracks, burn marks, or loose connections.

  • Trick: During your monthly testing, do a quick visual inspection of the outlets and surrounding wall plates for signs of wear and tear.

• Understand Indicator Lights:

  • Tip: Learn what the indicator lights on your GFCI tester mean. Different light patterns can indicate wiring issues, even if the GFCI test button works correctly.

  • Trick: Keep the tester’s instruction manual handy, or take a photo of the light code explanation and store it on your phone for quick reference.

When to call a Pro

Unless you are capable of changing a GFCI plug yourself you should call an Electrician in the following situations:

If the GFCI outlet does not trip when you press the test button on the tester, the outlet is not functioning correctly and should be replaced.

If the GFCI outlet does not reset after pressing the "Reset" button, it may be faulty and should be replaced.

If the power stays on after you hit the test button the GFCI is faulty and should be replaced.
