What is a GFCI?
GFCI of GFI is short for Ground Fault Circuit Interrupter. It is a special electrical outlet or circuit breaker designed to protect you from electrical shock. It works by monitoring the flow of electrical current to an appliance. It if senses electricity attempting to go to ground, it will trip the internal breaker. This is supposed to happen in less than a second. It works differently than the circuit breaker in the panel. The GFCI works with the breaker in your panel to provide an extra level of protection against electrical shock.
