Which statement describes the purpose of a test pull in conduit work?

• A. To measure tension limits
• B. To verify the conductor's electrical resistance
• C. To detect hidden obstructions before the pull
• D. To gauge cable color coding

Answer: (C)

Test pulls are done to check the path of the conduit before pulling any actual cables. By pulling a lightweight line through the conduit, the installer can feel for resistance, sharp bends, debris, or misaligned joints that would block or damage the cable during the real pull. Finding and addressing these obstructions beforehand prevents snags, excessive force, and potential damage to the conductors.

This can’t be confused with measuring how much tension the pull can safely handle—that’s a different part of the process. It also isn’t about testing the electrical resistance of the conductor or about identifying cable colors, which are practical tasks done after or separate from the pull.
