Which of the following articles focuses on wiring methods?

Article 300 of the National Electrical Code (NEC) is dedicated to the general requirements for wiring methods, covering a wide range of installation practices and material guidelines that ensure safe and effective electrical wiring. This article outlines the various types of wiring methods approved for use, the conditions under which they can be employed, and the installation specifications that must be met for compliance.

Understanding this article is essential because it not only sets the baseline safety and operational standards for wiring installations but also addresses aspects like securing and supporting conductors, burial depths for underground wiring, and requirements for raceways and cables. These guidelines help ensure that electrical installations are conducted safely and efficiently, minimizing risks such as electrical fires or equipment failures.

While other articles, such as Article 320, might address specific wiring methods like nonmetallic-sheathed cable, or Article 332 might focus on low-voltage wiring, Article 300 provides the overarching framework and fundamental regulations that apply across all wiring methods, making it the correct choice for focusing on wiring methods comprehensively.
