What are the grounding requirements for aluminum sheathed optical cables

Home / What are the grounding requirements for aluminum sheathed optical cables

The NEC recommends in Article 770 that non-current carrying metallic members (armor shield, metallic central member, and metallic strength member) of optical fiber cables be bonded and grounded at the point of entrance into a building or residence. Any cable that includes any conductive metal must be properly grounded and bonded in conformance with the comprehensive references to the National Electrical Code (NEC), ANSI and IEEE and NFPA Standards for safety. Proper grounding and bonding is required for the safe and e ective dissipation of. The National Electrical Code (NEC) provides clear guidelines for ground wire sizing through Table 250.
