What does GFCI stand for, and what is its function?

GFCI stands for Ground Fault Circuit Interrupter, and its primary function is to protect individuals from electrical shock. A GFCI is designed to detect imbalances in electrical current, which can occur when electricity is flowing through an unintended path, such as through water or a person. When it detects this imbalance, the GFCI quickly interrupts the circuit, thus preventing severe electrical shock or possible electrocution. This is especially important in areas where water and electricity may come into contact, such as kitchens, bathrooms, and outdoor settings. The effectiveness of a GFCI in enhancing safety in these environments underscores its critical role in electrical installations.
