Outer shields of Telco Cables serving the Operator Position shall be bonded using which gauge/length options?

• A. #10 AWG not exceeding 6 ft
• B. #6 AWG not exceeding 13 ft
• C. Both A and B
• D. Neither A nor B

Answer: (C)

Bonding the outer shield at the Operator Position must provide a solid, low-impedance path to equipotential ground while fitting practical installation limits. The standard allows two valid configurations: a bonding conductor of 10 AWG with a maximum length of 6 feet, or a bonding conductor of 6 AWG with a maximum length of 13 feet. Both options meet the required current-carrying capacity and impedance so the shield stays at the same potential as the equipment, minimizing stray voltages and protecting personnel and equipment. The thicker conductor is permitted for a longer bond because it can carry the fault current and keep impedance low over a greater distance. Therefore, either configuration is acceptable, making both options valid.
