Step-by-step explanation:
Receptacles that serve countertops are not to be located more than 18 inches above the countertop. This is specified in the National Electrical Code (NEC) which provides guidelines for electrical installations in the United States.
The purpose of this requirement is to ensure the safety and convenience of users. If receptacles are placed too high, it can be difficult to plug and unplug appliances, and there is a higher risk of accidents and electrical shock.
