Resistors and reactors are detailed in which article?

The correct identification of the article that details resistors and reactors is found in Article 470. This article specifically covers the requirements and regulations related to reactive equipment including resistors, reactors, and their applications in electrical installations. Article 470 provides important safety and performance standards to ensure that these components operate effectively and safely within electrical systems.

Focusing on resistors and reactors, this article outlines aspects such as their installation, ratings, and maintenance requirements, helping to ensure proper use in alignment with the electrical system's overall design and functionality. This understanding is crucial for electricians and engineers as they design and implement systems that comply with the National Electrical Code.

While other articles, such as Article 450, deal with transformers and Article 490 addresses induction motors and generators, Article 470 is specifically dedicated to the nuances of resistors and reactors, making it the appropriate reference for those components.
