Which NEC articles apply to broadband cable networks?

• A. Articles 820 and 830
• B. Articles 700 and 710
• C. Articles 230 and 240
• D. Articles 900 and 910

Answer: (A)

The essential idea is that broadband cable networks are treated as a communications cabling system within the NEC, with specific safety rules for both the distribution infrastructure and any network-powered equipment. One part covers the community antenna television and telecommunications distribution that runs the signal from a central point out to multiple premises, addressing how the coaxial cabling, connectors, grounding, protection, and related equipment are installed safely in multi-dwelling or multi-unit environments. The other part covers network-powered broadband communications systems, focusing on safety and wiring practices for remote equipment that is powered from the network and how it interfaces with the building’s electrical system. Together, these two areas directly address the practical needs of installing and safeguarding broadband networks—from the headend or central distribution to the individual customer drops and supporting equipment. Other NEC sections focus on different systems (like life-safety emergency systems or general overcurrent protection for feeders) and don’t specifically govern broadband distribution and network-powered devices, so they aren’t the primary references here.
