What does GFCI stand for in electrical safety?

GFCI stands for Ground Fault Circuit Interrupter. This device is designed to protect people from electric shock by monitoring the current flowing through a circuit. If a difference is detected between the electrical current flowing to and from a device—indicating that some of the current may be leaking to ground, potentially through a person—it quickly cuts off the electrical supply. This rapid response is crucial in preventing serious injury or fatality from electrical shocks, particularly in wet locations where the risk is higher, such as bathrooms or kitchens.

The other options do not accurately describe the function or purpose of a GFCI. For example, terms like "Current Initiator" or "Circuit Isolator" are not used in this context within electrical safety terminology. Understanding GFCIs is essential for ensuring safety in electrical installations and usage.
