When pulling a cable, the pulling force must not exceed what?

When pulling a cable, the pulling force must not exceed what?

• A. Conduit capacity
• B. Cable strength
• C. Rope capacity
• D. Pulling torque

Answer: (C)

The pulling force must stay within the cable’s strength. The cable is designed to withstand a certain maximum tensile load, and exceeding that limit can stretch, crack, or break the insulation and conductors, leading to failure or safety hazards. Conduit capacity relates to space inside the conduit, not how much force the cable can safely take. Rope capacity would matter only if you were evaluating the pulling rope itself, but the critical limit for pulling a cable is the cable’s own strength. Pulling torque describes the force available at the winch or motor, not the linear tensile limit of the cable itself. So, the safest and most accurate limit is the cable’s strength rating.
