Which article covers appliances and appliance circuits?

• A. Article 410: Luminaires and lighting equipment.
• B. Article 422: Appliances and appliance circuits.
• C. Article 400: Flexible cords and cables.
• D. Article 300: General wiring methods.

Answer: (B)

The topic being tested is identifying the NEC article dedicated to appliances and their circuits. The article that covers appliances and appliance circuits is the one named for that subject, and it provides the rules for wiring and supplying power to cord-and-plug–connected appliances, including how appliance circuits are sized and protected and what receptacle requirements apply. This article is distinct from others: the luminaires and lighting equipment article handles lighting fixtures, the flexible cords and cables article covers cords used with equipment, and the general wiring methods article focuses on broad installation practices for conductors and equipment. In short, appliances and their circuits are addressed in the article specifically titled for Appliances and Appliance Circuits.
