What is the maximum rated tension when pulling Four-pair 24 AWG UTP cable?

• A. 10 ft pounds
• B. 25 ft pounds
• C. 35 ft pounds
• D. 50 ft pounds

Answer: (B)

The main idea here is understanding how much force you should apply when pulling a cable to avoid damaging it. For four-pair 24 AWG UTP cable, the safe, recommended pulling tension is 25 pounds. This limit protects the delicate conductors and their insulation from excessive stretch or crush during installation, especially when pulling through walls, conduits, or pull boxes. Staying at or below this tension helps prevent issues like conductor damage, insulation cracking, or degraded terminations that could lead to faults or poor performance. Values higher than that (35 or 50 pounds) exceed what the cable is designed to tolerate during installation, increasing the risk of damage. A value as low as 10 pounds would be unnecessarily conservative and impractical for typical pulling tasks, though it would be safer than the recommended limit.
