Did you know there are two new codes regarding wiring methods added to the 2023 NEC®? This interactive online course 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.

Ryan Jackson is a combination inspector in the Salt Lake City, Utah, area. He began his career as a carpenter while in high school, and began doing electrical work at the age of 18. At the age of 23 Ryan landed his first job as an electrical inspector, and subsequently became certified in building, plumbing, and mechanical inspection, as well as building and electrical plan review. Two years after becoming an inspector, he was approached by a friend in the area asking him to fill in at an electrical seminar for him. After his first class he was hooked, and is now a highly sought after seminar instructor. Ryan has taught in several states, and loves helping people increase their understanding of the Code.


He has been involved in writing and editing over 25 books on the National Electrical Code, and has taught the subject in multiple states and for multiple colleges and universities. He is self-employed as an NEC® consultant and inspector.

When Ryan isn’t working, he can often be found in his garage turning wood on his lathe, in his basement exercising, or any quiet place where he can dive into a book. He is also a rabid University of Utah football fan. Ryan married his high school sweetheart, Sharie, and they have two beautiful children together: Kaitlynn and Aaron.
