Which article covers network-powered broadband communications systems installed within buildings?

• A. Article 800
• B. Article 840
• C. Article 830
• D. Article 860

Answer: (C)

The key idea is that the NEC assigns each type of low‑voltage system to a specific article, and the one that deals with systems powered over the network inside buildings is the article dedicated to network‑powered broadband communications systems. This article defines what counts as a network‑powered device, how power is delivered over the network, and the installation rules for cabling, equipment, and safety within a building to keep power and data paths compatible and safe. General communications circuits are covered under a broader article that spans many types of wiring, but it doesn’t include the specialized provisions for network‑powered broadband systems. Other articles address different building systems and don’t provide the NPBCS specifics. So the best fit is the article that specifically covers network‑powered broadband communications systems installed within buildings.
