GFCI: The Ultimate Protector

A Ground Fault Circuit Interrupter (GFCI) is a fast-acting circuit breaker that is designed to protect you from electrical shock. It constantly monitors the flow of electricity in a circuit and quickly cuts off the power if it detects any imbalance, such as electricity leaking into the ground or water.

How a GFCI Works

A GFCI works by comparing the amount of current flowing into a circuit with the amount of current flowing out. If there's a difference of even a few milliamps, it indicates that electricity is leaking somewhere, potentially through a person.

In response, the GFCI trips, interrupting the circuit and preventing electrical shock. This happens within a fraction of a second, making it an incredibly effective safety device.

Mandatory Protection

GFCIs are mandatory for pool light circuits and any other electrical outlets located near the pool. Their ability to quickly cut off power in the event of an electrical fault makes them an indispensable safety measure for preventing electrical shock injuries or death.
