Which NEC article governs Flexible Cords and Flexible Cables?

• A. Article 410
• B. Article 400
• C. Article 314
• D. Article 210.8

Answer: (B)

The concept being tested is which NEC article handles the rules for flexible conductors. Flexible cords and cables are covered comprehensively in Article 400. This section sets the requirements for the construction, rating, labeling, and appropriate use of flexible cords (like appliance cords and extension cords) and flexible cables, along with how they must be installed and terminated. It emphasizes that these cords are not a substitute for fixed wiring, requires proper strain relief and protection from physical damage at terminations, and specifies acceptable types and conditions of use based on listing and intended application. The other articles mentioned cover different topics—luminaires and accessories, boxes and fittings, and GFCI requirements—not flexible cords.
