What does GFCI stand for?

The term GFCI stands for Ground Fault Circuit Interruption. This device is essential for increasing electrical safety in areas where electrical shock hazards may exist, such as bathrooms, kitchens, and outdoor locations. A GFCI monitors the amount of current flowing in a circuit. If it detects an imbalance in the electrical current, which may happen if there is a fault, it interrupts the circuit within a fraction of a second, significantly reducing the risk of electrical shock.

Understanding the function of a GFCI is crucial for electrical safety because it acts as a protective measure that can prevent severe injuries or fatalities due to electrical shocks. The other options listed do not accurately describe the function of the device or use incorrect terminology, making it important to recognize the correct terminology for proper understanding and application in practice.
