Which article is related to phase converters?

Phase converters are addressed in Article 455 of the National Electrical Code (NEC). This article specifically outlines the requirements for various types of phase converters, including their installation, operation, and safety considerations. Phase converters are used to convert single-phase electrical power into three-phase power, which is necessary for running three-phase motors and equipment that require such power for optimal performance.

The provisions within Article 455 ensure that these converters are safely installed, maintained, and used, which is critical for both efficiency and electrical safety. Understanding this article is essential for electricians working with phase converters to ensure compliance with electrical codes and to implement safe working practices.
