Which type of circuit breaker is specifically designed for protection against ground faults?

• A. Standard circuit breaker
• B. Arc-fault circuit interrupter (AFCI)
• C. Ground fault circuit interrupter (GFCI)
• D. Dual function circuit breaker

Answer: (C)

The ground fault circuit interrupter (GFCI) is specifically designed to provide protection against ground faults, which occur when there is an unintended path between a source of current and the ground. This may happen when electrical current leaks from a circuit and can pose significant risks, including electrical shocks or fire hazards. GFCIs monitor the electrical current flowing through a circuit and will trip or shut off the power if they detect an imbalance, which indicates that some of the current is escaping to the ground. The design and function of a GFCI are essential for safety in areas where moisture is present, such as kitchens, bathrooms, and outdoor spaces, where the likelihood of ground faults is higher. This proactive safety measure prevents harmful electrical incidents by quickly disconnecting power to the circuit when a fault is detected. While other types of circuit breakers such as standard circuit breakers and arc-fault circuit interrupters also serve important functions in protecting electrical systems, they do not specifically address ground faults. Standard circuit breakers primarily protect against overloads and short circuits, and arc-fault circuit interrupters are designed to prevent fire hazards caused by arc faults. Dual function circuit breakers combine features of both GFCI and AFCI but are not solely designed for the purpose of ground fault
