What is the maximum height of pull boxes or junction boxes that requires all conductors to be cabled or racked in an approved manner?

The maximum height of pull boxes or junction boxes, where all conductors must be cabled or racked in an approved manner, is specified as 6 feet. This requirement is in place to ensure that electrical conductors within these enclosures are properly organized and reduce the risk of issues such as overheating, short circuits, or physical damage due to improper handling.

At heights above this maximum, the NEC allows for alternative methods of organization and securing conductors, recognizing that accessibility and ease of management can become more challenging. By regulating the maximum height, the NEC aims to promote safety and consistency in electrical installations, ensuring that conductors remain easy to access and maintain.

In practical terms, this means that electricians and contractors need to pay special attention to how they install and manage conductors within pull boxes and junction boxes up to that 6-foot height to comply with NEC standards effectively.
