Article 230 in the NEC covers what aspect of electrical work?

Article 230 of the National Electrical Code (NEC) specifically addresses the installation requirements for electric services, which include power supply systems that deliver electricity to buildings or structures. This section outlines the standards for service entrance conductors, service equipment, and disconnecting means, ensuring that electrical services are safely and effectively brought to the load.

Understanding this is critical for electricians, as it establishes essential safety protocols and installation practices for connecting buildings to the utility grid. This article provides guidelines on both overhead and underground service configurations, including proper clearances, grounding requirements, and metering arrangements.

The other choices relate to different aspects of electrical systems: feeders are primarily covered in a different section related to distribution, switchboards and panelboards are also discussed under separate articles, and health care facilities have specific requirements found elsewhere in the NEC. Recognizing the focus of Article 230 ensures that electricians can effectively manage electrical service installations in compliance with national standards.
