What is the recommended mounting height for the 20-amp receptacles above a counter?

The recommended mounting height for 20-amp receptacles above a counter is indeed 8 inches. This height is established to ensure accessibility and convenience for users while also maintaining compliance with electrical codes. Mounting the receptacle at this height allows for easy access without being obstructed by countertop appliances or other items that may be placed on the counter. Furthermore, a height of 8 inches helps mitigate the risk of splashes or spills that could occur at lower heights, which is particularly important in kitchens and workspaces. This standard height strikes a balance between accessibility, functionality, and safety in various settings.
