Which article governs the installation of flexible cords and cables used in general electrical installations?

• A. Article 400: Flexible cords and cables.
• B. Article 422: Appliances and appliance circuits.
• C. Article 310: Conductors for general use.
• D. Article 334: NM cables.

Answer: (A)

Article 400 governs flexible cords and cables used in general electrical installations. This section covers how flexible cords and cables are constructed, rated, terminated, and protected when they connect equipment to a power source. It explains where these cords can be used (typically for movable or temporary connections) and sets rules to prevent misuse as permanent wiring, along with requirements for proper strain relief, protection from damage, and appropriate outdoor or indoor ratings. The other articles address different wiring topics—appliances and appliance circuits, NM cables for fixed wiring, and general conductors—so they don’t cover the specific rules that apply to flexible cords and cables.
