Under which circumstance are 125-volt, 20-ampere receptacles serving kitchen countertops required to have GFCI protection?

• A. Under some circumstances
• B. Only if specified by local code
• C. Under all circumstances
• D. Only for commercial kitchens

Answer: (C)

GFCI (Ground Fault Circuit Interrupter) protection is crucial in areas where moisture is prevalent, such as kitchens. For 125-volt, 20-ampere receptacles serving kitchen countertops, the National Electrical Code (NEC) requires GFCI protection under all circumstances to enhance electrical safety and prevent electric shocks. This requirement is based on the understanding that kitchens often involve water and other conductive materials, which can create hazardous situations if a fault occurs. Having GFCI protection means that if there is any ground fault—like a person touching a live appliance while standing on a wet floor—the GFCI will detect the imbalance in electrical current and cut off the power quickly, reducing the risk of severe electric shock. This encompasses all residential installations, ensuring a consistent standard for safety in any residential kitchen countertop area.
