Question: 1 / 400

What does GFCI stand for?

Ground Fault Circuit Interrupter

GFCI stands for Ground Fault Circuit Interrupter. This device is designed to protect people from electrical shock by detecting ground faults, which occur when there's an unintended path between the source of current and a grounded surface. When a GFCI senses that the electric current is flowing along an unintended path, it quickly cuts off the electrical supply, significantly reducing the risk of shock or electrocution. These devices are commonly used in areas where moisture is present, such as bathrooms, kitchens, and outdoor locations, where the risk of ground faults is heightened. Their primary function is to enhance safety by preventing electric shock injuries, making them a crucial component in residential and commercial electrical systems.
