Prior to attempting a pull in all but very short runs, the wires should be _____

• A. Not lubricated
• B. Lightly lubricated
• C. Heavily lubricated
• D. Lubricated

Answer: (D)

Friction inside conduit is the main enemy of a smooth pull. Applying an approved lubricant to the wires before pulling lowers the resistance between the cable jacket and the conduit walls. That makes the pull easier, reduces the risk of jacket damage, and lowers the chances of kinks or insulation damage from high forces. This is standard practice for most pulls beyond very short runs, so lubrication helps ensure a safer, faster installation. Use a lubricant that is compatible with the cable jacket and the conduit, and apply it where friction is greatest, reapplying as needed for long pulls.
