When renovating or even during a basic home maintenance checkup, you might come across the term GFCI outlet and wonder, “What is a GFCI outlet, and how is it different from regular ones?” Worry not, because this comprehensive guide will explain everything from what GFCI stands for to how to fix a GFCI outlet that's not working.
Among the different types available, GFCI outlets stand out because of their safety features. This guide will help answer all your GFCI-related questions and help you understand, install, and use these outlets in your home.
What Are GFCI Outlets?
What does GFCI stand for? The acronym stands for Ground Fault Circuit Interrupter. This type of outlet prevents electrical shock by shutting off the power when it detects an imbalance between the incoming and outgoing current. If an electrical fault interrupts the circuit, like someone touching an exposed wire or a blown fuse, the GFCI outlet will cut off the power supply, preventing potential harm.
GFCI outlets are different from other outlets because they have a built-in safety feature that monitors the electrical current. This feature makes GFCI outlets particularly useful in areas where water is present, like your kitchen or bathrooms.
Types of GFCI Outlets
There are various GFCI Outlet types.
1. Indoor vs. Outdoor
While the fundamental purpose remains the same, an outdoor GFCI outlet is designed to withstand rain and temperature fluctuations.
2. GFCI Outlet with USB
Modern homes require modern solutions. A GFCI outlet with USB is a blend of safety and convenience, allowing you to charge your devices directly without needing a charger.
3. Amps: 15 vs. 20 vs. Recommended Usage
- 15-amp: Suitable for many smaller residential appliances.
- 20-amp: Best for larger electrical devices or high-load areas.
Consider the devices you'll plug into the outlet and whether the circuit ratings match when deciding between the two. The amps (amperage) of the outlet should never exceed the amperage of the circuit. For example, you can install a 15-amp electrical outlet to a 20-amp circuit. However, you should never install a 20-amp GFCI outlet to a 15-amp circuit.
How to Install GFCI Outlet
GFCI outlet wiring is the same as regular outlets, but the added safety features mean you’ll need to be extra careful.
Installation Steps:
- Turn off the power supply.
- Disconnect the old outlet.
- Connect the ground wire to the new outlet.
- Connect the neutral and hot wires.
- Screw the new GFCI outlet into the wall box.

Troubleshooting Tips on GFCIs
- GFCI Outlet Keeps Tripping: This can often result from a ground fault, when electricity breaks loose from its path and heads toward the ground, like lightning. Check for moisture or any damaged appliances connected to the outlet.
- GFCI Outlet Not Working: Ensure it's not a circuit breaker issue. Then, try resetting the outlet.
- GFCI Outlet Won't Reset: This is likely due to a ground fault but can also be due to a lack of power caused by a tripped breaker or a broken component in the outlet.
