What Is a GFCI Outlet—and Why Every Home Needs One
GFCI stands for ground fault circuit interrupter, a critical safety device in residential electrical systems. It automatically shuts off power when it detects that electrical current is traveling along an unintended path—such as through water or a person—helping prevent electric shocks. GFCI outlets are especially important in moisture-prone areas like bathrooms, kitchens, garages, and outdoor spaces. If a plugged-in cord becomes faulty or wet, the GFCI will immediately cut the power, reducing the risk of serious injury or even death. Upgrading to GFCI-protected receptacles is a simple yet essential step in improving home electrical safety.
