The conduit inside is cleaned and polished before the cable is pulled by which tool?

• A. Wire brush
• B. Conduit smoother
• C. Conduit brush
• D. Rag and solvent

Answer: (C)

Cleaning and smoothing the inside of the conduit before pulling cable is done to reduce friction and prevent damage to the cable jacket as it passes through bends and ridges. A conduit brush is the best tool for this job because it is specifically designed to clean the interior surfaces of conduit, reaching along the walls to scrub away dust, burrs, and corrosion and leave a cleaner, smoother surface. This helps the pull go more easily and minimizes snagging or tearing of insulation. Using a wire brush can leave loose bristles or scratch the walls, potentially causing damage or contamination; rag and solvent may leave lint or residue and won’t thoroughly clean the full interior; a conduit smoother isn’t the standard cleaning tool for preparing the interior. So, the conduit brush fits the task precisely.
