Article 378 covers which type of raceway?

Article 378 of the National Electrical Code (NEC) specifically addresses Nonmetallic Wireways. Nonmetallic wireways are used for the protection and routing of electrical conductors and are designed to help organize wiring in a clean and efficient manner. This article outlines the requirements for installation, materials, and construction standards for these types of raceways.

Nonmetallic wireways are advantageous because they are lightweight, corrosion-resistant, and can be more aesthetically pleasing compared to their metal counterparts. Additionally, they do not conduct electricity, offering an extra layer of safety in various applications. Understanding the standards set forth in this article is essential for anyone working with these raceways to ensure safety and compliance with electrical codes.
