What function does a GFCI provide in an electrical system?

• A. Enhances power efficiency
• B. Prevents circuit overloads
• C. Protects against ground faults and electrical shock
• D. Controls the flow of electrical current

Answer: (C)

A Ground Fault Circuit Interrupter (GFCI) plays a crucial role in protecting individuals from electrical shock and preventing ground faults. It is designed to detect imbalances in electrical current. When the GFCI senses that the current flowing through the circuit is not returning through the neutral wire—indicating a potential path to ground, such as through a person—it quickly interrupts the circuit. This rapid disconnection of power reduces the risk of severe electric shock that could occur if a person were to make contact with live electrical parts while simultaneously grounded. GFCIs are particularly important in wet or damp locations, such as bathrooms, kitchens, and outdoor outlets, where the risk of electrical shock is higher. By effectively monitoring the current and acting swiftly to cut power when a ground fault is detected, GFCIs serve a vital safety function in electrical systems.
