Plenum cables must comply with which NEC article?

Explanation:
Plenum cables fall under the scope of the communications circuits, which is covered by Article 800. Cables used in air‑handling spaces must be plenum-rated (CMP) to resist fire and limit smoke spread, and Article 800 specifically governs the installation and rating of communications cabling in those environments. The other articles address different types of conductors or equipment and don’t cover communications cabling in plenums (for example, general conductors are in Article 310, medical equipment in Article 620, and Article 118 isn’t the standard for this cabling).
