What does GFCI stand for and what is its purpose?

GFCI stands for Ground Fault Circuit Interrupter, and its primary purpose is to protect individuals from electrical shock, particularly in areas where the risk of electrical hazards is higher, such as kitchens, bathrooms, and outdoor settings. A GFCI monitors the amount of current flowing in a circuit and quickly disconnects the power if it detects an imbalance, which can occur when current flows through an unintended path, such as through water or a person. This rapid response significantly reduces the risk of serious injury or death from electrical shock. GFCIs are an essential safety feature in residential wiring, ensuring that electricity is used safely in various environments.
