What does Article 300 cover in terms of wiring installations?

Article 300 of the National Electrical Code (NEC) outlines the general requirements for wiring methods and materials. This article serves as a foundation for electrical installations, detailing various essential aspects such as permissible wiring methods, types of materials that can be used, and installation practices that ensure safety and compliance with code. By addressing the broad specifications for how wiring should be correctly and safely installed, it ensures that all subsequent articles related to specific applications, such as lighting fixtures or high voltage wiring, can refer back to these general standards.

The focus on general requirements establishes a consistent basis for electrical safety, helping electrical professionals understand and apply various wiring methods effectively across different types of installations. This foundational knowledge is crucial for ensuring that all wiring projects meet safety standards and local regulations.
