Which article would you refer to for guidelines on capacitors?

The guidelines for capacitors are found in Article 460 of the National Electrical Code (NEC). This article specifically addresses the installation and protection of capacitors, including specifications on their ratings, enclosures, and associated equipment.

It outlines safety measures and installation practices that must be adhered to in order to ensure that capacitors operate safely and efficiently within electrical systems. Knowing the provisions of Article 460 is crucial for anyone involved in the design and implementation of electrical systems that utilize capacitors, as it helps to mitigate risks associated with their operation.

The other articles listed address different components and systems: Article 455 deals with fixed capacitors, while Article 480 focuses on storage batteries. Article 490 covers transformers and reactors. Therefore, the specific focus of Article 460 makes it the right reference for guidelines on capacitors.
