The minimum length of a box used in a straight pull installation is specified as 8 times the trade size of the raceway. This is crucial for providing sufficient space to accommodate the conductors within the box while allowing for safe and easy access for maintenance or adjustments. The larger box size helps to prevent excessive bending of the conductors, which can lead to potential damage or violations of electrical codes.

In a straight pull scenario, the conductors need to be routed without sharp bends, and the 8 times requirement ensures that there is an appropriate amount of space for this. It also aids in promoting good wire management and reducing the likelihood of overcrowding, both of which are important for ensuring the longevity and performance of the electrical system.

This guideline helps electricians to meet code requirements in safe and effective ways during installation, protecting both the integrity of the wiring and the safety of the environment they are installed in.
