Which NEC article governs the installation of feeders and associated conductors?

• A. Article 410 (Luminaire mounting)
• B. Article 725 (Class 2 and 3)
• C. Article 215 (Feeders)
• D. Article 520 (Theatrical)

Answer: (C)

Feeder conductors and their installation are governed by Article 215. A feeder is the set of conductors and equipment that carry power from the service disconnecting means (or from the last overcurrent device) to the next distribution point, such as a subpanel or downstream equipment. Article 215 provides the rules for sizing the conductors (ampacity), overcurrent protection, and how these feeders are installed and terminated, including neutrals and grounding as applicable. This is distinct from branch circuits, which are covered by Article 210. The other articles mentioned deal with different topics (luminaire mounting, Class 2/3 circuits, theatrical lighting), not feeders.
