What does a GFCI do?

The primary function of a Ground Fault Circuit Interrupter (GFCI) is to protect against electrical shock. It does this by continuously monitoring the current flowing in a circuit and quickly disconnecting the power if it detects any imbalance between the incoming and outgoing current, which can occur when there is a fault or leakage current that could occur if someone comes into contact with the electrical source. This rapid disconnection minimizes the risk of serious injury or death from electric shock.

Understanding the importance of a GFCI is crucial in areas where electrical equipment is likely to be used near water, such as bathrooms, kitchens, and outdoor locations. Its role is vital in enhancing safety in these environments.
