What is the focus of Article 450 in the National Electrical Code?

Article 450 of the National Electrical Code specifically addresses transformers and transformer vaults. This article outlines the requirements for the installation and operation of transformers that are used to convert electrical energy from one voltage level to another. The focus includes topics such as transformer locations, installation methods, and the protection of transformer vaults against fire hazards and other risks.

Transformers play a crucial role in electrical systems, allowing for efficient power distribution by stepping voltage levels up or down as needed. This ensures that electrical energy can be transmitted over long distances without significant loss and can be appropriately used in residential, commercial, and industrial settings. By focusing on both transformers and the design and safety considerations for transformer vaults, Article 450 ensures that installations are not only functional but also safe for users and the surrounding environment.
