A Test Pull will detect any hidden obstructions in the conduit before pulling. What is the correct choice?

• A. Hidden obstructions in the conduit
• B. Cable diameter
• C. Ambient temperature
• D. Electrical grounding

Answer: (A)

Before pulling cable, you want to confirm that the conduit path is clear. A Test Pull uses a lightweight line or mandrel to run through the conduit as a dry run, allowing you to detect any hidden obstructions by feeling for resistance. If resistance is found, you can address the obstruction before the actual cable pull, preventing damage to the cable and installation delays. The other options don’t fit because they don’t reveal obstruction in the conduit: cable diameter is a specification of the cable itself, ambient temperature affects pulling conditions but not obstruction detection, and electrical grounding relates to safety rather than detecting obstructions in the conduit.
