Which statement about pulling methods is true?

• A. Manual pullers are preferred because they can apply less stress.
• B. Electric pulling equipment is avoided due to cost.
• C. Pulling methods do not affect cable stress.
• D. Electric pulling equipment is preferred because manual pullers apply too much stress to the cable.

Answer: (D)

Controlling pulling tension during installation is essential to protect the cable from damage. Manual pulling can be inconsistent and easy to over-apply force, especially over long runs or through bends, which can stress the insulation and conductors. Electric pulling equipment gives a controlled, adjustable pull and often includes tension monitoring, so the force stays within safe limits. This reduces the risk of overstressing the cable and helps maintain proper bend radius and smooth movement through conduits. The other statements aren’t correct because manual pulling is not inherently gentler, pulling method does affect stress, and cost isn’t the main reason to avoid or choose equipment—the safety and integrity of the cable are.
