What does GFCI stand for in electrical systems?

GFCI stands for Ground Fault Circuit Interrupter. This device is designed to protect people from electric shock by monitoring the electricity flowing through a circuit. If it detects any imbalances in the current—such as might occur when current escapes a circuit and flows through a person to the ground—it quickly interrupts the electrical flow. This can happen in as little as 1/40 of a second, making GFCIs crucial for safety in areas where water is present, such as kitchens and bathrooms. Understanding the function of a GFCI is important in residential wiring because it plays a significant role in reducing the risk of electrical shock and potential electrocution in homes.
