The class begins with an in-depth exploration of the significant changes made to Chapters 2 [Wiring & Protection] in the 2020 National Electrical Code® (NEC). This is a critical Chapter, addressing the most central provisions of the NEC for safe and reliable wiring materials and protective devices that affects almost every kind of electrical installation. The class next provides a survey of every significant change made to Chapter 5 [Special Occupancies], an extremely complex Chapter that is generally considered the most difficult to master. It governs situations requiring special electrical precautions due to hazardous substances, critical services being provided, or higher risks to the public and other users.
This class next presents the significant change made to Chapter 7 [Special Conditions] in the 2020 National Electrical Code® (NEC-2020). This is the most varied Chapter in the NEC, including the provisions for such special conditions as emergency back-up systems, limited power circuits, and optical fiber cable as well as the rapidly changing Articles on direct current microgrids, interconnected sources of power supply, energy storage, and stand-alone systems. The changes to Chapter 8 [Communication Systems] now include a General Requirements Article for Communication Circuits followed by a substantial revision and reorganization. The class finishes with the single change to Chapter 9 [Tables].
Each change in this course on Chapters 2, 5, 7, 8 & 9 is presented first with a thumbnail to help orient the student and provide a ready means for reviewing the material. The NEC-2020 language for the affected code is then provided, with any deletions and revisions from NEC-2017 clearly shown. Most importantly, each change is accompanied by a thorough-going discussion of what the change means and the reason it was installed in the Code. The discussion includes, where possible, the reasons provided by the relevant code-making panel that oversaw the change and any vital contributions to the discussion from working electricians, manufacturers, and industry analysts. The goal is to express every change in clear language, to focus on how the changes should be applied by a working electrician, and to provide the resources to explore the change more fully for those who wish to do so.
