What does NEC Article 314 require about the height of service boxes?

NEC Article 314 outlines various requirements for the installation of boxes for electrical work, including service boxes, which are critical for ensuring safety and accessibility. The correct standard regarding the height of service boxes typically stipulates that they should be installed in a manner suitable for accessibility, and while local codes can dictate specific measurements, the general guideline provided is that the height should not exceed 6 feet 7 inches above the floor. This measurement ensures that the boxes are accessible to users without the need for ladders or other equipment, promoting safety and convenience in maintenance or operation.

The rationale behind this height requirement is to make sure that electrical boxes are easily reachable for inspection, maintenance, or integration into the wiring system, aligning with principles of safety and ease of access. This standard promotes a uniform approach to installation across different settings, facilitating compliance and reducing the risk of accidents associated with improperly positioned service boxes.
