What is the minimum distance required between each raceway entry inside an electrical box and the opposite wall?

The minimum distance required between each raceway entry inside an electrical box and the opposite wall is based on best practices for avoiding interference and maintaining safety in electrical installations. Specifically, the requirement is that this distance should be no less than six times the trade size of the largest raceway entering the box. This guideline helps to ensure that there is adequate space for the conductors, promotes easier installation, and allows for proper heat dissipation, minimizing potential damage and ensuring reliable operation of the system.

In practice, having sufficient distance between raceway entries and the wall of the electrical box helps reduce the risk of damage to the conductors and allows for efficient management of any potential cable bending radius requirements. It also assists in maintaining the integrity of the electrical installation over time, thus enhancing safety and performance.
