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 Chapter 2 NEC-2020.
Each change presented in the class is accompanied by a thoroughgoing 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.
After the overview and introduction to the class, thirteen new or revised definitions from Chapter 1 [General] are covered, including “Equipotential Plane”, “Free Air”. “Grounded Conductor”. “Island Mode”, and “Reconditioned”. The significant changes to four general requirements complete this portion of the class, including changes to 110.12 Mechanical Execution of Work, 110.14 Terminal Connection Torque, 110.22 Identification of Disconnecting Means, and Spaces About Electrical Equipment.
The class next presents 45 critical changes made to Chapter 2 on “Wiring and Protection”. Some of the most far-reaching discussed are Emergency Disconnect rules and Surge Protection Requirements (in a new Article 242), along with the first major revision of lighting load calculations since 1971.
