Which article covers Underground Feeder and Branch-Circuits Cable?

The correct article that covers Underground Feeder and Branch-Circuit Cable is Article 338. This article specifically addresses the requirements and specifications for using UF (underground feeder) cable, which is designed for direct burial in the ground and for use in wet conditions without requiring additional conduit. Article 338 outlines the construction, installation, and uses for UF cable, ensuring safety and compliance with the National Electrical Code standards.

In contrast, Article 330 pertains to the use of metal-clad cable and associated installation practices, which focuses on different types of cable structures and applications. Article 344 discusses the requirements for rigid metal conduit, which is related to protecting electrical wiring but does not cover underground feeder cables specifically. Article 332 deals with nonmetallic-sheathed cable, which is also not intended for underground use in the same manner as UF cable. Thus, Article 338 is the most accurate source for the guidelines concerning Underground Feeder and Branch-Circuit Cable.
