Montana 16 Hour 2020 NEC Package

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 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. There are revised GFCI provisions for Basements & Indoor Damp/Wet Locations; Specific Appliances & Equipment; Outdoor Outlets; Feeders and for Temporary Feeders.

This portion of the class finishes with 29 significant changes from Chapter 3 [Wiring Methods and Materials], including the reorganization of Article 310 and Ampacity Tables, a new Article on Type P Cable, and a new Article 311 on Medium Voltage Cable.

The next portion of the 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.

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.

This class is followed by coverage of every significant change made to Chapter 5 [Special Occupancies] This is an extremely complex Chapter, 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.

There are 5 changes to the Articles on Hazardous (Classified) Locations, including Combustible Gas Detection Systems; New Protection Techniques for Equipment, Type TC-ER-HL and Type P Cable; and Table 505.9(C)(2)(4) for Zone 0, 1, and 2 Locations.

The class follows this with every significant change made to Chapters 8 [Communication Systems. A review of seven changes drawn from Articles 800 & 805 follows, providing details on the repurposing of Article 800 for General Requirements and the reorganizations and revisions for the Sections moved or added to the new Article 805. The class finishes this look at Chapter 8 with two changes to the increasingly important Premises-Powered Broadband Communications Systems: 1) Circuits Leaving the Building and 2) Powering Communications Equipment over Communications Cables. The class finishes with one change made to Chapter 9 [Tables].
