In a pull box where all conductors enter the left side and exit the bottom, what is the minimum top-to-bottom length (inches)?

In a pull box where all conductors enter the left side and exit the bottom, what is the minimum top-to-bottom length (inches)?

• A. 34 in.
• B. 24 in.
• C. 44 in.
• D. 32 in.

Answer: (C)

The main idea is that pull box dimensions are driven by room for box fill plus space to pull and bend conductors without crowding. When all conductors enter from the left and exit through the bottom, you must route them to make a 90-degree turn toward the bottom exit. That path uses vertical space inside the box, and enough top-to-bottom height is needed to lay out the conductors with proper slack and separation while keeping bends and splices accessible. Because this configuration requires more room to accommodate the bend and to prevent crowding, a taller box is required. Among common practical dimensions, 44 inches provides the minimum vertical space to satisfy these pulling and layout needs. Smaller heights would not leave enough room for the conductors to be arranged safely and code-compliant.
