Which of the following equipment does Article 430 primarily apply to?

• A. Transformers only
• B. Generators only
• C. Electric motors
• D. Lighting fixtures

Answer: (C)

Article 430 of the National Electrical Code (NEC) specifically addresses the requirements for electric motors and their associated equipment. This includes guidelines on proper installation, maintenance, and safety measures that need to be considered when working with electric motors. The purpose of Article 430 is to provide detailed information on motor branch circuits, overload protection, motor control, and disconnects among other requirements, ensuring that these components operate safely and efficiently. Since electric motors are integral to many industrial and commercial applications, Article 430 establishes standards to mitigate the risks associated with their use, such as overloading and short circuits. While transformers, generators, and lighting fixtures are also important components in electrical systems, they are governed by different articles within the NEC that are tailored to their specific characteristics and operational concerns. Therefore, the primary application of Article 430 is clearly focused on electric motors.
