What is one of the benefits of using a GFCI in electrical systems?

Using a Ground Fault Circuit Interrupter (GFCI) in electrical systems is primarily aimed at enhancing safety by preventing electrical shocks. One of the key benefits of a GFCI is its ability to detect imbalances in the electrical current. When there is a difference between the current flowing into a circuit and the current returning, which can happen if a person comes into contact with the electrical source, the GFCI quickly cuts off the power.

This protection is crucial in areas where water is present, such as kitchens and bathrooms, where the risk of electrical shock is higher. By effectively reducing the potential for shock hazards, GFCIs play an essential role in preventing serious injuries and fatalities that can result from electrical accidents.
