GFI vs. GFCI: What’s the Difference?

What is GFI?

GFI is just short for ground fault interrupter outlet. This is a specific type of outlet that is usually placed in wet or damp locations in a building to identify ground faults in circuits and cut off power to prevent electric shock. We give importance to local protection by mentioning GFIs when discussing local outlets or receptacles, whose circuit tripping capability is confined to the specific areas of installation.

The need for a GFI receptacle arises from the characteristics of the electric current. An electric current needs to move from a section of the circuit with high potential (the energized area) to an area with lower potential. The current will follow the easiest route to the ground. The GFI outlet or receptacle is designed to prevent electric shock by tripping the circuit when it senses a ground fault or circuit leakage.

What is GFCI?

The GFCI outlets or receptacles, typically found in bathrooms and kitchens, are specialized and distinct. GFCI stands for ground fault circuit interrupter and is a device that stops electricity from reaching a faulty appliance or fixture by detecting a difference in current between the hot and neutral sides. GFCIs can function either as a circuit breaker or as a receptacle connected to an electrical outlet. The GFCI circuit breaker, which is placed in the distribution panel, is meant to interrupt the current for all outlets located further down the circuit.
