If you have ever noticed an outlet in your bathroom or kitchen with two small buttons labeled "Test" and "Reset," you have seen a Ground Fault Circuit Interrupter, or GFCI outlet. These specialized outlets are designed to protect you from electrical shock, and they are required by electrical code in specific areas of your home.
How GFCI Outlets Work
A GFCI outlet continuously monitors the flow of electrical current through the circuit. Under normal conditions, the current flowing out through the hot wire and returning through the neutral wire should be equal. If the GFCI detects even a tiny difference — as small as 4 to 5 milliamps — it assumes that current is leaking through an unintended path, such as through a person's body or through water, and it shuts off the circuit in as little as one-thirtieth of a second.
Where GFCI Outlets Are Required
Current electrical codes require GFCI protection in these areas:
- Bathrooms
- Kitchens (all countertop outlets)
- Garages
- Outdoor outlets
- Basements and crawl spaces
- Laundry areas
- Areas near swimming pools and hot tubs
Testing Your GFCI Outlets
GFCI outlets should be tested monthly to ensure they are working properly. Press the "Test" button — you should hear a click and the power to the outlet should shut off. Then press "Reset" to restore power. If the outlet does not trip when you press "Test," or if it does not reset properly, it may need to be replaced.
GFCI outlets have a limited lifespan and can wear out over time. If your GFCI outlets are more than 10 years old, consider having them tested by an electrician to ensure they are still providing proper protection.
Need Professional Help?
If your Pittsburgh home is missing GFCI outlets in required areas, or if your existing GFCI outlets are not functioning properly, a licensed electrician can install or replace them quickly. A licensed electrician ensures your home meets current safety standards with properly installed GFCI protection.
