What is the minimum distance allowed between angle or U pulls and the opposite wall of the box?

The minimum distance allowed between angle or U pulls and the opposite wall of the box is defined as six times the trade size of the largest raceway. This requirement is based on ensuring adequate space for proper installation and operation of conductors as well as preventing any potential mechanical stresses on the wires.

In electrical installations, bends and pulls can cause conductors to experience tension, especially when cables are directed towards a box. If the distance is insufficient, it may lead to damaged insulation or even electrical shorts if conductors become pinched. The standard of six times the trade size is a widely accepted guideline to provide a safe and practical working space.

This distance requirement aligns with established codes and industry guidelines, which highlight the importance of providing enough room for technical considerations such as pull tension, conductor maintenance, and ease of future modifications or inspections. Therefore, adhering to this regulation is key in ensuring a safe and efficient electrical installation.
