What is required for all 125-volt, 15- and 20-ampere receptacles serving kitchen countertops?

All 125-volt, 15- and 20-ampere receptacles serving kitchen countertops must have GFCI (Ground Fault Circuit Interrupter) protection for personnel. This requirement is critical because kitchen environments often have water sources, which increase the risk of electrical shock. GFCI outlets are designed to detect ground faults and cut off electricity quickly, thereby protecting users from potential electrical hazards such as shocks or electrocution.

The use of GFCI protection in such situations adheres to safety standards outlined in the National Electrical Code (NEC), promoting safe practices when using electrical devices near water. Ensuring that kitchen countertop receptacles are GFCI protected enhances safety, particularly in areas where moisture is prevalent.

This requirement comes into play especially in residential kitchens where appliances might frequently be used near sinks or areas that can become wet. It's a crucial safety feature that has been widely implemented to reduce accidents and injuries related to electrical use in damp locations.
