The first three-plus hours of the class reviews every notable change made to Chapter 4 in the 2020 National Electrical Code® (NEC-2020). Chapter 4 is one of the core Chapters in the NEC and contains some of the most widely applied as well as the most frequently updated provisions of the NEC regarding safe and reliable installation of equipment for general use.
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.
This class presents 38 significant changes to Chapter 4, including a revision to the defined Scope of the NEC in Article 90, new Panelboard Circuit Directory Locations, and enhanced Identification of Power Sources for Storage Batteries. The class also covers important code revisions (or newly added codes) on:
- A New Type of Fixture Wire - FFHH-2;
- Rating and Use of General-Use Snap Switches Dimmers and Control Switches;
- Electronic Control Switches;
- Installation Requirements of Controlled Receptacles;

- Electronically Protected Motor Circuits and Controllers;
- Emergency Shutdown in One- and Two-Family Dwelling Units;
