What is the maximum distance a receptacle can be placed above a dwelling unit kitchen countertop surface?

In accordance with the National Electrical Code (NEC), the maximum height for receptacles installed above kitchen countertop surfaces is set to ensure they are both accessible and safe for use. The correct answer, which indicates that receptacles can be installed at a maximum height of 20 inches above the countertop, highlights the intention of NEC to promote convenience for users who often operate appliances or devices on the countertop.

Receptacles installed above countertops must be easily reachable to facilitate use for various kitchen appliances such as mixers, toasters, and coffee makers. Allowing a maximum height of 20 inches strikes a balance between keeping the receptacles out of the way of kitchen activities while ensuring accessibility.

Therefore, adhering to this guideline helps ensure that the electrical installations in kitchen areas meet safety standards and provide functionality for everyday kitchen tasks.
