Which article in the NEC predominantly addresses general wiring methods?

Article 300 of the National Electrical Code (NEC) is the section that predominantly addresses general wiring methods. This article outlines the requirements for installing conductors and cables, including their protection, support, and routing. Understanding Article 300 is essential for ensuring that wiring systems are installed safely and effectively, meeting the necessary safety standards.

Article 100 provides definitions for terms used in the NEC but does not focus on specific wiring methods. Article 200 covers the general requirements for overcurrent protections and the design of branch circuits, which are important but not specifically about wiring methods. Article 400 details specific wiring methods and materials, such as flexible cords and cables, but it is not the primary article for general wiring methods. Therefore, Article 300 stands out as the critical reference for wiring installations within the NEC.
