When it comes to protecting your home and family from electrical shock, GFCI outlets (Ground Fault Circuit Interrupters) are one of the most important—and often overlooked—features in your electrical system.

At Selkirk Electric, we install and upgrade GFCI outlets for homeowners across North Idaho, making sure homes meet modern electrical code and safety standards. In this post, we’ll explain what GFCI outlets are, how they work, and where you absolutely need them in your home.

What Is a GFCI Outlet?

A GFCI outlet is a type of electrical receptacle designed to quickly shut off power when it detects a ground fault—an unintentional electrical path between a power source and a grounded surface. In simple terms, it helps protect you from being shocked if electricity is leaking in an unsafe way.

These outlets are easily recognized by the "TEST" and "RESET" buttons on the faceplate.

How Does It Work?

GFCI outlets monitor the electrical current flowing in and out of the outlet. If the amount of electricity going out doesn’t match what’s coming back in—even by a small amount (as little as 4 to 6 milliamps)—the GFCI will shut off power in less than a second.

This is especially critical in wet or damp environments, where the risk of shock is higher.

Where Should GFCI Outlets Be Installed?

The National Electrical Code (NEC) requires GFCI protection in the following areas:

  • Bathrooms
  • Kitchens (within 6 feet of a sink)
  • Laundry rooms
  • Garages
  • Unfinished basements
  • Outdoor outlets
  • Crawl spaces
  • Utility sinks
  • Wet bars
  • Pool and spa areas

If your home is older, it may not have GFCI outlets in all the required areas—putting your family and your property at risk.

Signs You May Need GFCI Upgrades

  • You don’t see TEST and RESET buttons on outlets in your kitchen, bathroom, or garage
  • Outlets in wet areas are two-pronged instead of grounded
  • The outlet trips frequently or won’t reset
  • You recently renovated but didn’t update your wiring

➡️ Pro Tip: You can test your GFCI outlet by pressing the TEST button. This should cut power to anything plugged in. Press RESET to restore power.

Why It Matters for Safety and Code Compliance

Installing GFCI outlets isn’t just about checking a box—it’s about protecting your family from potentially fatal electrical shocks. These outlets also help prevent fires caused by ground faults.

Plus, if you’re selling your home or undergoing renovations, missing GFCIs can delay inspections or violate code.
