What is the allowed maximum height for mounting an outlet box for accessibility?

The maximum height for mounting an outlet box for accessibility is 48 inches. This standard is established to ensure that electrical outlets are reachable by individuals using wheelchairs or those with limited mobility. The goal is to provide equal access to electrical outlets for everyone, which is essential in public accommodations and certain residential settings.

Positioning the outlet box at or below 48 inches allows for easier access, aligning with guidelines from the Americans with Disabilities Act (ADA). When considering the overall layout of a space, this measurement supports usability and ensures that a wide range of individuals can effectively utilize the electrical system without undue strain or inconvenience.

Other options do not meet the accessibility standards outlined in the NEC and ADA, as they either exceed the recommendations for easy reach or imply less accessibility.
