Proper routing of shielded cables reduces wear from movement by

• A. Securing and following proper bend radii
• B. Allowing loose routing and frequent flexing
• C. Providing proper support and secure routing
• D. Avoiding any support and leaving them on floor

Answer: (C)

Movement wear on shielded cables happens when the cable can move, rub, or flex against surfaces along its route. Providing proper support and secure routing constrains the entire run to a defined path, with clamps, ties, and strain relief at terminations. This keeps the cable from shifting and rubbing, reduces vibration-induced flexing, and helps preserve the shielding and insulation. While following bend radii is important to prevent sharp stress points, the essential factor for minimizing wear from movement is keeping the cable firmly supported and securely routed. Loose routing or leaving cables unprotected increases movement and wear, while placing them on the floor invites damage.
