GFCI Outlets: Why They Matter and Where They’re Required

When it comes to electrical safety, few devices are more essential—or more misunderstood—than GFCI outlets. Short for Ground Fault Circuit Interrupter, a GFCI is a specially designed outlet that cuts off power when it detects a ground fault—an unintended path between electricity and the ground, which could lead to electrical shock or even electrocution.



At Ebert Electric in New London, Wisconsin, we regularly install and upgrade GFCI outlets in homes and businesses to ensure they meet safety codes and provide peace of mind. In this blog, we’ll explain what GFCIs do, why they’re important, and where the National Electrical Code (NEC) requires them.

What Is a GFCI Outlet?

A GFCI outlet monitors the flow of electricity in a circuit. If it detects even a slight imbalance—like electricity leaking through water or a person—it shuts the power off in a fraction of a second. This small but powerful device helps prevent serious injury or death due to electric shock.

You can recognize a GFCI outlet by the "Test" and "Reset" buttons on its face. If tripped, pressing "Reset" restores power. These outlets should be tested monthly to ensure they’re functioning correctly.

Where Are GFCIs Required?

The NEC mandates GFCI protection in any area where water and electricity are likely to mix. As of the most recent code updates, here’s where GFCIs are required:

• Kitchens: Any outlet serving countertop areas.
• Bathrooms: All outlets.
• Garages: All 125-volt, single-phase, 15- and 20-amp outlets.
• Unfinished Basements: With few exceptions.
• Laundry Rooms: Especially where outlets are near sinks or water sources.
• Outdoor Outlets: Every exterior outlet.
• Crawl Spaces and Wet Bar Sinks: Any area with moisture potential.
• Boathouses and Pool Areas: For obvious safety reasons.

If your home was built or wired before these codes were in place, it may not have the proper protection—and that puts you at risk.

Why GFCI Protection Is Critical

GFCIs are not optional—they’re a first line of defense against deadly electrical shock. In older homes, or in buildings with outdated wiring, they are especially important. They also protect your appliances from surges and can reduce the risk of fire caused by ground faults.

Not having them installed in the required areas could result in failed home inspections, code violations, or worse—accidents that could have been prevented.
