What does GFCI stand for?

The term GFCI stands for Ground Fault Circuit Interrupter. This device is designed to prevent electrical shock by interrupting the circuit when it detects an imbalance between the incoming and outgoing current. Essentially, if there is a ground fault—meaning electricity is leaking from the circuit, possibly through a person— the GFCI will trip and cut off the electrical supply. This is particularly critical in wet environments, such as bathrooms or kitchens, where the risk of electric shock is higher. Understanding the function and importance of GFCIs is essential for electrical safety, as they protect individuals from potentially lethal situations caused by faulty wiring or appliances.
