Which NEC article covers communications systems?

• A. Article 800
• B. Article 430
• C. Article 450
• D. Article 480

Answer: (A)

Communications systems are addressed in Article 800. This portion of the NEC covers circuits and equipment used to carry voice, data, video, and other information within and between buildings, including the wiring methods, conductors, cables, raceways, and enclosures, as well as installation, protection, grounding, and bonding requirements to ensure safe and reliable operation and to prevent interference with other electrical systems. The other topics listed focus on motors (Article 430), transformers (Article 450), and storage batteries (Article 480), which are not about communications circuits, so they don’t apply to communications systems.
