Which article would you refer to for guidelines on outside branch circuits?

Article 225 of the National Electrical Code (NEC) specifically addresses the requirements for outside branch circuits and feeders. This article covers the installation and maintenance of conductors that are intended to supply electric power to locations that are outside of buildings. It offers guidelines on the ratings, locations, and installation practices required to ensure safe and reliable operation of these circuits.

The article emphasizes considerations such as the protection of conductors, physical installation requirements, and necessary ratings to withstand environmental influences like moisture and corrosion, which are critical factors when dealing with outside installations. Thus, when seeking to understand how to safely and effectively implement outside branch circuits, Article 225 is the definitive reference.
