When pulling cable in conduit, how often should pull boxes be specified?

Every 50 feet
Every 100 feet or after 180 degrees of bend
Every 200 feet
Every 150 feet

The correct answer is: Every 100 feet or after 180 degrees of bend

When pulling cable in conduit, specifying pull boxes is essential for managing cable tension and ensuring smooth cable installation. The correct practice is to place pull boxes every 100 feet or after a bend that exceeds 180 degrees. This guideline helps to reduce the strain on the cables during the pulling process, as long runs without a pull box can lead to excessive tension and potential damage to the cables. When bends are introduced in the conduit run, they add resistance to the pulling effort. A pull box allows the cables to change direction without having to maintain a continuous pull over a long distance, which can be challenging and may result in issues such as kinking or breaking of the cable. Therefore, placing pull boxes under these conditions—whether at a specified distance or after a certain number of bends—ensures a more reliable installation. This method adheres to industry standards and helps maintain the integrity of the cabling system during installation.
