Which statement best defines pulling tension in a limited-energy cabling installation and how should it be controlled?

• A. The force applied to cabling during a pull; control with tensioners, lubrication, and within manufacturer limits.
• B. The electrical resistance of the cable under load.
• C. The speed of the pull, independent of tension.
• D. The color code used for wires.

Answer: (A)

Pulling tension is the force applied to cabling during a pull, and it must be controlled to prevent damage to the cable during installation. The best approach is to use tensioners to maintain a steady, within-specified pull, apply lubrication to reduce friction in conduits and bends, and stay within the cable manufacturer’s maximum pulling tension. This combination helps prevent stretching, insulation damage, or jacket failure and reduces the risk of future faults at terminations. Other statements describe aspects that aren’t about the mechanical force of pulling: electrical resistance under load relates to how the cable conducts electricity, not how hard you pull; the speed of the pull can affect tension but isn’t the definition of pulling tension; and the color code is about identifying conductors, not the pulling process.
