Which statement describes a combination device that provides both GFCI and AFCI protection?

• A. It provides only GFCI protection
• B. It provides only AFCI protection
• C. It provides neither GFCI nor AFCI protection
• D. It provides both GFCI and AFCI protection

Answer: (D)

A device that combines ground-fault protection and arc-fault protection in a single unit gives you both safety features in one outlet or breaker. GFCI works by watching the current running through the hot and neutral wires and trips if there is any leakage to ground, which helps prevent electric shock. AFCI looks for the electrical patterns associated with arcing and trips to prevent fires caused by loose connections or damaged insulation. When a single device provides both, it’s designed to monitor for either condition and interrupt the circuit as needed, giving enhanced protection in locations where both risks exist. The other descriptions would only offer one type of protection or none, so they don’t describe a dual-function device.
