Part three covers some of the 2023 updates in the National Electrical Code, including changes to Articles 300, 310, 312, and 314. These changes will address items such as protection against physical damage to wiring, underground installations, and the number of conductors in a raceway, as well as supports for enclosures and conduit bodies. We will also discuss outlet box installation and ratings, so get charged up on the updates to the NEC here.

 

Part four covers the changes to wiring methods in the 2023 National Electrical Code. Articles covered in this course include Articles 320, 334, 336, 342, 352, 356, 358, 369, and 371. Article 320 covers armored cable (Type AC). Article 334 covers non-metallic-sheathed cables (Types NM and NMC). Article 336 covers power and control tray cable (Type TC). Article 342 covers intermediate metal conduit (IMC). Article 352 covers rigid polyvinyl chloride conduit (PVC). Article 356 covers liquid-tight flexible nonmetallic conduit (LFNC). And Article 358 covers electrical metallic tubing (EMT). Notable changes include the addition of Article 369, which covers insulated bus pipe (IBP)/tubular covered conductors (TCC), and Article 371, which covers flexible bus systems. By the end of the course, learners will understand the critical regulations, best practices, and safety considerations for wiring methods outlined in 2023 NEC.
