What is the maximum pulling force value for Cat5 wire as cited by industry guidelines?

• A. 15
• B. 25
• C. 30
• D. 50

Answer: (B)

Cat5 cables are very sensitive to pulling tension, so industry guidelines set a safe maximum pulling force to protect the cable’s conductors and insulation during installation. Limiting the pull to 25 pounds helps prevent stretching or damaging the jacket and strands, which could loosen terminations, degrade electrical performance, or lead to future connection failures. Staying at or below this limit supports reliable data transmission and long-term durability as the cable is routed through walls, ceilings, or conduit. In metric terms, that’s about 111 Newtons, which gives practical help when planning pulls and using tools like pull strings or conduit to avoid overloading the cable.
