Which NEC article covers motors and motor circuits?

• A. Article 480
• B. Article 800
• C. Article 430
• D. Article 600

Answer: (C)

Motors and their circuits have dedicated rules in the NEC because motors impose unique requirements, such as high inrush currents and the need for proper overload protection and a disconnecting means. The article that covers motors, motor circuits, and controllers provides the specific provisions for sizing motor conductors, selecting overcurrent protection, and arranging motor controllers and disconnects. It also addresses how motors are wired and protected in practice, ensuring safe and reliable operation.

The other articles cover topics like transformers (not motors), communications circuits, and other equipment types, so they don’t address the specialized needs of motors and their circuits.
