What does GFCI stand for in safety devices?

GFCI stands for Ground Fault Circuit Interrupter. This safety device is designed to protect individuals from electric shock by monitoring the electrical current flowing through a circuit. If it detects an imbalance in the electrical current, such as when current flows through an unintended path—like a person's body—the GFCI interrupts the circuit, cutting off the electrical flow almost instantly.

The effectiveness of a GFCI is especially crucial in environments where moisture is present, such as bathrooms, kitchens, and outdoor settings, as water increases the risk of shocks. By providing this essential protection, GFCIs help to prevent serious injuries or fatalities related to electrical hazards. This makes understanding GFCIs important for anyone involved in electrical work or safety practices.
