When pulling high-speed data cable, the pulling tension should not exceed how many foot-pounds?

When pulling high-speed data cable, the pulling tension should not exceed how many foot-pounds?

• A. 15
• B. 25
• C. 35
• D. 50

Answer: (B)

Controlling pulling tension is essential to protect the cable and its terminations during installation. If you pull too hard, the cable can stretch, the insulation or conductors can be damaged, and the connectors or terminations may fail, which can degrade performance in high-speed data runs. A maximum of 25 foot-pounds is the standard limit because it provides enough force to pull the cable through bends and through spaces without risking damage, while staying conservative enough to preserve signal integrity. Pulling at higher levels, such as 35 or 50 foot-pounds, increases the risk of damage to the cable or its terminations. On the other hand, a limit as low as 15 foot-pounds can make pulling long or through complex routes impractical. Use proper technique and aids—lubricant, appropriate pulling hardware, and attention to bend radius—to stay within the 25 foot-pounds guideline.
