What is the recommended practice when pulling multiple cables through a conduit to prevent damage and kinks?

• A. Use pull strings or fish tape, apply lubricant if allowed, avoid sharp bends, and use pull boxes when needed.
• B. Pull all cables without guides or lubrication.
• C. Only one cable at a time with no lubricant.
• D. Force cables through the conduit regardless of bend radius.

Answer: (A)

The main idea is to control the path and reduce the friction on cables as they move through a conduit, protecting them from damage and kinks. Use a pull string or fish tape to guide the cables so they don’t twist or catch on the conduit walls. Lubricant helps the cables slide more easily, reducing friction and potential insulation wear—use it only if the project specs allow. Keep bends gentle to avoid sharp turns that can kink or pinch the conductors. When the run requires it, use pull boxes to change direction or relieve pulling force, making the pull safer and more controlled. This combination minimizes damage and makes pulling multiple cables through a conduit smoother and safer. Skipping guides, skipping lubrication, forcing cables through, or pulling with no regard to bend radii all increase the risk of damage and kinks.
