Under NEC, which article covers communications circuits?

• A. Article 800
• B. Article 820
• C. Article 805
• D. Article 830

Answer: (C)

Communications circuits are addressed in Article 800 of the NEC. This article sets the rules for wiring and equipment used by communications systems—things like telephone and data networks, as well as signaling circuits—including what conductors and cables can be used, how they’re installed in raceways or spaces, and how they’re protected and grounded. It also covers how these low‑voltage circuits must be separated from higher‑voltage power conductors to prevent interference and safety issues. So when you’re dealing with communications circuits, the NEC reference you use is Article 800, not other articles that cover different electrical topics.
