What is the maximum height for storing the coupling means of electric vehicle supply equipment at outdoor charging sites?

The correct response is based on the National Electrical Code (NEC) guidelines, which specify requirements for electric vehicle supply equipment (EVSE) installations. The maximum height for storing coupling means, such as connectors and charging cables, is set to ensure accessibility and safety. By maintaining a height limit of 4 feet for these coupling devices, it allows for convenient access for users of all heights, including those who may have mobility issues.

Storing these components at this height not only aids in usability but also helps prevent accidents or damage to the equipment that might occur if they were placed higher, making them difficult to reach or manage. This specific standard is critical in promoting safe practices in the design and deployment of outdoor charging stations. Thus, adhering to the 4-foot height limit for storing coupling means aligns with these safety and accessibility guidelines, making it the correct choice.
