Question: 1 / 445

What is the purpose of a GFCI in electrical systems?

To prevent electrical shocks

The purpose of a Ground Fault Circuit Interrupter (GFCI) is primarily to prevent electrical shocks. GFCIs are designed to detect imbalances in electrical current, which can occur when electricity flows through an unintended path, such as through water or a person. When a GFCI detects this imbalance, it quickly cuts off the electrical supply, significantly reducing the risk of severe injury or electrocution.

This safety device is particularly important in environments where electrical equipment is used near water, such as kitchens, bathrooms, and outdoor locations, as moisture increases the risk of electrical shock. The GFCI does not enhance battery performance, increase voltage levels, or specifically reduce power consumption; its critical function is to provide protection against electric shock hazards.
