Which NEC Article covers Network-Powered Broadband Communications Systems?

• A. NEC Article 725
• B. NEC Article 800
• C. NEC Article 820
• D. NEC Article 830

Answer: (D)

The key idea here is that Network-Powered Broadband Communications Systems have their own dedicated NEC article because the way these systems are powered and protected is different from other communications wiring. This article lays out the specific rules for installing NPBS, including how power is supplied from the network, grounding and overcurrent protection, wiring methods, and equipment compatibility. It focuses on safety and reliability for systems whose power originates remotely from the network, rather than from on-site building power. That specialization is what distinguishes NPBS from the broader communications circuits article, CATV-related provisions, or the Class 2/3 circuits article.
