For angle pulls of conductors 4 AWG and larger, what is the minimum distance required between raceway entries?

The minimum distance required between raceway entries for angle pulls of conductors that are 4 AWG and larger is specified as 6 times the diameter of the raceway. This requirement ensures that the angle pull is managed safely and effectively, minimizing stress on the conductors as they bend and transition into the raceway.

This standard helps to maintain the integrity of the insulation and conductor materials by allowing adequate space for the conductors to navigate the bend without excessive strain. A distance that is too short could lead to potential damage or increased wear on the conductors, adversely affecting their performance and safety.

Ensuring a minimum clearance of 6 times the diameter creates better conditions for the physical handling of the conductors during installation and reduces the risk of overheating and potential failures due to tight bending radii. Following this guideline is essential for compliance with electrical codes and standards, which are designed to promote safe and reliable electrical installations.
