The class begins with a broad introduction to the changes made to the 2020 National Electrical Code® (NEC-2020). It includes a brisk discussion of the code review process, a detailed explanation of how the NEC is organized, and coverage of code-wide changes, new Articles for 2020, and the changes to Article 100 (Definitions) and Article 110 (Requirements for Electrical Installations). It then presents every significant change made to Chapters 2 and 3 of NEC-2020. These are the two most critical Chapters in the NEC, 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.
Each change presented in the class is accompanied by a thorough discussion of what the change means and the reason it was installed in the Code. 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.
