Which NEC article specifically covers electric motors?

• A. Article 430
• B. Article 310
• C. Article 550
• D. Article 240

Answer: (A)

The National Electrical Code (NEC) Article 430 specifically addresses electric motors and the associated components required for their installation, operation, and maintenance. This article outlines the requirements for motor branch circuits, including sizing conductors, overload protection, and disconnect means. By focusing on motor-specific applications, Article 430 helps ensure safe and efficient operation of electric motors in various settings, including residential, commercial, and industrial environments. This emphasis on electric motors includes important details such as the calculation of full-load currents and the necessary ratings for various components to guarantee proper motor function and safety. Other articles in the NEC deal with different aspects of electrical installations and do not specifically focus on electric motors, making Article 430 the primary reference for this subject in the code.
