Any hidden obstructions in the conduit can be detected before the pull by _____.

• A. Visual inspection
• B. Tapping with weight
• C. A test pull
• D. Using a borescope

Answer: (C)

The main idea is to verify the conduit path before pulling by performing a test pull. A test pull means running a lightweight line or pulling a small, controllable load through the conduit to simulate the actual pull. As you apply the pull, you check for any resistance or snagging. If the path is clear, the line moves smoothly; if you feel resistance, it indicates an obstruction or excessive friction that should be addressed before the real conductors are pulled. This proactive check helps prevent damage to cables, stuck pulls, and delays. Visual inspection or a borescope can help if you have access to the entire length, but many conduit runs are long and hidden, and these methods may miss tight bends or subtle obstructions. Tapping with weight is not a reliable way to identify hidden blockages in a conduit path. A test pull directly tests the actual pulling conditions and reveals obstructions or friction that would impact the final pull.
