When should lubricant be applied during cable installation?

• A. Before starting
• B. During movement
• C. After the basket
• D. After completion

Answer: (C)

Lubricant is used to reduce friction where the cable rubs against surfaces during a pull, so you want it applied where the cable will actually contact those surfaces as you pull it through the basket and into the duct. Applying the lubricant after the cable is loaded into the basket ensures the coating is on the portions that will experience the most friction right from the start of the pull, giving a smoother, safer installation. Applying it before starting can lead to uneven coverage and mess, while applying only during movement or after completion defeats the purpose of easing the pull in the critical friction points.
