What Does GFI Stand For?
GFI stands for Ground Fault Interrupter
GFI, or Ground Fault Interrupter, is a safety device designed to protect people from electric shock by detecting ground faults—unintended electrical paths between a power source and the ground. It continuously monitors the current flow and quickly disconnects the power supply if an imbalance is detected, reducing the risk of electrical accidents in wet or high-risk environments. GFIs are commonly used in residential and commercial settings, particularly in bathrooms, kitchens, and outdoor areas.
