Angle pull dimensional requirements apply to junction boxes only when the size of conductors is equal to or larger than which AWG?

Angle pull dimensional requirements are important for ensuring that conductors are installed in a way that prevents damage and maintains the integrity of the electrical system. These requirements specifically pertain to the bending radius and the physical arrangement of the conductors in junction boxes when the conductors are of a certain size.

In this context, the threshold for applying these angle pull requirements is set at size 4 AWG conductors. When conductors are equal to or larger than size 4 AWG, the risk of mechanical stress and potential damage due to inadequate bending radius becomes critical. Consequently, ensuring that junction boxes are appropriately sized and configured for these conductors helps in facilitating proper handling of electrical loads and enhances the safety and functionality of the installation.

For conductors smaller than size 4 AWG, the typical bending radius and arrangement can be more lenient, as they can accommodate tighter bends without risking damage. Thus, the application of the angle pull dimensional requirements is specifically focused on conductors at size 4 AWG and larger, reflecting the increased importance of maintaining appropriate handling procedures at larger sizes.
