Which article governs Flexible Cords and Flexible Cables?

• A. Article 410
• B. Article 400
• C. Article 314
• D. Article 680

Answer: (B)

Flexible cords and cables are addressed by Article 400. This article covers cords used for plug-in connections and portable equipment, including how they are constructed, rated, and installed. It sets rules about not using flexible cords as a substitute for fixed wiring, requiring proper strain relief at connections, and specifying protection from damage and appropriate locations for running them. The other articles mentioned relate to different topics—lighting fixtures (Article 410), boxes and enclosures (Article 314), and swimming pool or spa equipment (Article 680)—so they don’t govern flexible cords.
