What is the minimum height requirement for the coupling means of electrical vehicle supply equipment outdoors?

The minimum height requirement for the coupling means of electrical vehicle supply equipment outdoors is established to ensure safe operation and accessibility. A height of 24 inches above ground level is set to provide a balance between practical use and minimizing the risk of accidental contact or interference with the equipment.

This height helps protect the equipment from potential environmental hazards such as flooding, as well as from mechanical damage that can occur if the equipment is mounted too close to the ground. Moreover, placing the coupling means at this height allows users to connect and disconnect charging equipment comfortably without bending down too far, thereby improving usability and compliance with safety standards.

Other height options either do not provide adequate clearance or may make operation inconvenient or less safe, highlighting why the 24-inch requirement is the accepted standard.
