Industry standards such as the NEC (National Electrical Code) Article 770 and NFPA 70 provide binding requirements, while standards from IEEE and TIA offer additional guidance. This Applications Engineering Note (AE Note) discusses conventional bonding and grounding practices for conductive fiber optic cable and hardware installations within the scope of the National Electrical Code (NEC). NEIS® are intended to be referenced in contrac documents for electrical construction ation or liability to users of this publication. This section of the National Electrical Code specifically addresses the unique characteristics and hazards associated with transmitting light for control. Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. Sections are included for project management; cable handling, testing and equipment; overhead cable placement; underground cable placement; underground enclosures; bonding and grounding; cable. 40.
