How high must kitchen and dining room countertop receptacle outlets be installed above the countertop surface?

The proper installation height for kitchen and dining room countertop receptacle outlets is specified in the National Electrical Code (NEC). According to NEC Article 210.52(C)(1), receptacle outlets for the countertop must be installed so that the top of the outlet is no less than 15 inches above the countertop surface.

This height is determined to ensure accessibility while also minimizing potential exposure to water spills, which are more common in kitchen areas. By setting a minimum height of 15 inches, the code promotes safety and practicality in everyday kitchen use.

While 20 inches may seem reasonable, it exceeds the minimum requirement, and the 15-inch standard strikes the right balance between convenience and safety. Thus, the answer aligns perfectly with the NEC guidelines for receptacle outlet installation in kitchens and dining areas.
