What is the minimum height at which a receptacle can be installed above a countertop?

The minimum height at which a receptacle can be installed above a countertop is indeed 15 inches. This requirement, specified in the National Electrical Code, ensures that electrical outlets are conveniently accessible for use while also maintaining safety considerations in kitchen and work areas.

Installing receptacles at this height allows for the practical use of appliances that may be placed on the countertop without causing excessive strain on cords or posing a tripping hazard. Additionally, it helps to protect the receptacles from being splashed with water or affected by kitchen activity, which could lead to safety hazards.

This placement aligns with general accessibility criteria and promotes a functional and safe environment in areas where food preparation and equipment are used.
