Which category does Article 225 in the NEC pertain to?

Article 225 of the National Electrical Code (NEC) specifically addresses outside branch circuits and feeders. This article outlines the requirements for the installation of electrical systems that transport power from the service equipment or a source to various outdoor locations. It covers topics such as wiring methods, equipment ratings, grounding and bonding requirements, and special conditions that need to be considered when dealing with circuits operating outdoors.

The focus on outside branch circuits and feeders is essential because these installations may face different environmental challenges compared to indoor circuits, such as exposure to the elements, which can affect the integrity and safety of the electrical system. Therefore, understanding and applying the guidelines set forth in Article 225 is crucial for ensuring safe and code-compliant outdoor electrical installations.
