Which article contains guidelines for phase converters?

Phase converters, which are used to convert single-phase electrical power to three-phase power, are addressed in Article 455 of the National Electrical Code (NEC). This article provides guidelines and requirements specifically for the installation and use of phase converters, ensuring they are set up safely and effectively to operate equipment that requires three-phase power.

Understanding the content of Article 455 is important for anyone involved in electrical installations that utilize phase converters, as it outlines standards for equipment ratings, installation practices, and safety measures. This helps to prevent hazards associated with improper setup, such as overheating or equipment failure.

Other articles mentioned do not pertain specifically to phase converters; for example, Article 450 deals with transformers, Article 470 covers inductors, and Article 480 focuses on storage batteries, which are unrelated to the topic of phase conversion. Hence, it is crucial to reference Article 455 for any guidelines related to phase converters.
