The minimum left-to-right length of the pull box, given the current conduit arrangement, is what value (inches)?

• A. 37 in.
• B. 30 in.
• C. 40 in.
• D. 33 in.

Answer: (A)

The main idea is that a pull box must have enough room for the conductors to be pulled and spliced without crowding, while also meeting box-fill requirements. The left-to-right dimension is driven by how many conductors are in each conduit run, plus the slack needed for splices and to maintain proper bending radii as you pull the wires through. In this arrangement, the conduits leave enough room only if the box is about 37 inches long, which gives just enough horizontal space to lay out the conductors, clamps, and any grounding conductors without crowding or tight bends. Shorter lengths would force crowding or awkward pulls, while a longer length isn’t necessary for the minimum requirement. So the smallest length that satisfies both pulling space and box-fill considerations is 37 inches.
