In a pull box, if Conduits H and K contain the same conductors, what is the minimum distance, in inches, between Conduits H and K?

In a pull box, if Conduits H and K contain the same conductors, what is the minimum distance, in inches, between Conduits H and K?

• A. 21 in.
• B. 39 1/2 in.
• C. 28 in.
• D. 42 1/2 in.

Answer: (A)

In a pull box, there’s a minimum separation required between conduits that carry the same conductors on opposite sides. This space ensures the conductor bundles can be fed through without rubbing, snagging, or crowding as you pull them in, and it gives enough room to handle and inspect the conductors inside the box. The smallest spacing that meets this requirement is 21 inches, which is why that option is the correct choice. The other distances exceed the minimum and aren’t necessary unless the box or conductors call for more room, so they aren’t the best fit for the question.
