Which of the following values represents the recommended Cat5 wire pull strength in pounds?

• A. 20
• B. 25
• C. 30
• D. 40

Answer: (B)

When installing Cat5 cable, you’re guarding against damaging the cable from pulling stress. The recommended maximum pull strength is 25 pounds. This limit strikes a balance: it’s strong enough to pull the cable through walls, conduits, or tight spaces, but low enough to prevent harming the insulation, twisting of the pairs, or weakening terminations. Exceeding this limit (like 30 or 40 pounds) raises the risk of crushing the sheath, deforming conductors, or loosening connections, which can lead to performance problems. A value like 20 pounds is safer but not the standard maximum guideline; it would simply allow a gentler pull but isn’t the commonly cited maximum.
