Montana 8 Hour 2020 NEC Changes to Chapters 4, 5, 8, & 9
- 8 Hour Course
This class covers a wide range, from the widely used Equipment for General Use of Chapter 4, to the highly specialized codes and Chapter 5, and the stand-alone codes of Chapter 8, which now include a "General Requirements" Article for Communication Circuits followed by a substantial revision and reorganization of the Chapter.
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 in the 2020 National Electrical Code®., 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.
