For the left-side configuration with 4-inch conduits on one row and 2-inch conduits on another, performing a U-pull between two 4-inch conduits on the side, what is the minimum left-to-right length (inches)?

For the left-side configuration with 4-inch conduits on one row and 2-inch conduits on another, performing a U-pull between two 4-inch conduits on the side, what is the minimum left-to-right length (inches)?

• A. 28 in.
• B. 42 in.
• C. 24 in.
• D. 34 in.

Answer: (A)

The main idea is that a U-pull around two large conduits needs enough straight run to form the curved portion around those conduits and still clear the adjacent row. With a left-side setup where 4-inch conduits form the pull path and smaller 2-inch conduits sit on the other row, the pulling line must travel out enough from the left edge, curve around the outer sides of the two 4-inch conduits, and then line up with the opposite conduit on the right. When you account for the space taken by those large conduits and the clearance needed for the U-shaped bend in that specific arrangement, the straight left-to-right distance has to be about 28 inches. Anything shorter wouldn’t provide enough room for the bend without contacting a conduit; anything longer isn’t required for this configuration, so 28 inches is the minimum.
