What bonding/grounding requirement is needed for armored sheath fiber cable?

Armored sheath fiber cable uses metallic armor, so the armor can become energized if a fault occurs. To keep safety and proper fault clearing, the armor must be both bonded to the equipment grounding conductor and grounded to the earth. Bonding creates a continuous low-impedance path for fault currents, ensuring all conductive parts are at the same potential and enabling overcurrent protection to operate reliably. Grounding ties the system to the earth, providing a stable reference and helping dissipate surges or lightning-induced currents. Together, proper bonding and grounding of the armored sheath prevent shock hazards and improve fault protection, which is why the required approach is to bond and ground the armor.
