How Do You Install A GFI Circuit Breaker?
GFI stands for Ground Fault Interrupt, and GFI circuit breakers are also known as GFCI (Ground Fault Circuit Interrupt) breakers. They work the same way regular circuit breakers do–cutting off the power to a portion of your home in the event of an electrical surge–but they also prevent shocks caused by leaking water and similar hazards. In that sense, they are much safer than regular circuit breakers. Installing a GFI circuit breaker is just as easy as installing a regular one–there is just one additional wire involved in the process. Open your circuit box and cut the power to your house by throwing the main switch. Disconnect the metal frame surrounding the circuit box with a screwdriver, then set it and the screws aside. Locate the breaker you wish to replace and turn it off. Then remove it from its housing, either by unscrewing it or popping it out. Unscrew the wiring connected to the terminals on the old circuit breaker and slide the wires free. Turn the new GFI circuit breaker
