For straight pulls of 2 AWG conductors through a junction box, the length of the box shall be at least ___ times the size of the largest raceway.

For straight pulls of 2 AWG conductors through a junction box, the length of the box shall be at least ___ times the size of the largest raceway.

• A. 5
• B. 7
• C. 10
• D. 8

Answer: (D)

The requirement for the length of a junction box during straight pulls of conductors is based on the need to ensure adequate space for the conductors to be pulled through without causing damage or undue stress. The code specifies that for straight pulls, the length of the junction box must be at least 8 times the size of the largest raceway involved. This allows for a smooth transition of the conductors, preventing issues such as kinking or excessive bending that could compromise the integrity of the conductors. In this specific case, with 2 AWG conductors, following the 8 times rule ensures compliance with safety standards and facilitates easier and safer future maintenance or modifications. This regulation exists to promote proper installation practices and is in place to enhance the overall safety and reliability of electrical systems.
