What type of wiring method does Article 300 cover?

Article 300 of the National Electrical Code (NEC) addresses the general requirements for all wiring installations, making it a fundamental aspect of electrical work. This article provides guidelines that are applicable to various types of wiring methods and systems, emphasizing safe practices regardless of the specific materials used, installation location, or voltage levels.

The provisions detail essential aspects such as the proper ways to install conductors, maintain physical protection, and ensure support. This broad scope ensures that all types of wiring installations adhere to the safety standards and operational efficiency required for electrical systems, thus promoting consistency and reliability in electrical work across different configurations.

Understanding this context highlights the importance of Article 300 as a comprehensive regulatory framework for electrical installations, making it clear why it encompasses general requirements rather than being confined to specific contexts such as non-metallic systems, underground installations, or high voltage systems.
