What is the focus of Article 230 in the NEC?

Article 230 in the National Electrical Code (NEC) specifically addresses service installations. This article outlines the requirements for how electrical services should be provided to buildings or structures, including the type and size of conductors, the means of connecting to the utility supply, and the necessary protections and clearances involved in service installations.

In this context, the article is essential for ensuring that service installations are performed safely and efficiently, providing guidelines that protect both the installation and the occupants. While related topics like feeders or general installation practices are covered in other articles, Article 230 focuses solely on the delivery of electrical service from the utility provider to the building. This distinction is crucial for understanding how electrical systems are supplied with power and the specific codes that govern those installations.
