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, 3 & 4 of NEC-2020.
These are the three “core” Chapters in the NEC, addressing the provisions that govern almost every electrical installation, barring any specialized circumstances. The class finishes up by presenting every significant change made to Chapter 5, 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.
Each change in Chapters 1-5 is presented first with a “thumbnail” to help orient the student and provide a ready means for reviewing the material. The 2020 NEC language for the affected code is then provided, with any deletions and revisions from the 2017 NEC clearly shown. Most importantly, each change is accompanied by a thorough-going discussion of what the change means and the reason it was installed in the Code. The discussion includes, where possible, the reasons provided by the relevant code-making panel that oversaw the change and any vital contributions to the discussion from working electricians, manufacturers, and industry analysts.
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 every significant change made to Chapter 6 in the 2020 National Electrical Code® (NEC-2020). Chapter 6 governs electrical connections to specialized equipment. Since this specialized equipment often sees the greatest innovation and most rapid changes of any in the electrical field, it also sees a host of NEC revisions during every code renewal cycle, including the 2017-2020 code review cycle.
The class presents 54 changes to Chapter 6 -- the greatest number of significant changes to any Chapter in the 2020 NEC. It begins with five changes to Article 600 [Electric Signs and Outline Lighting]; two to Article 620 [Elevators, Dumbwaiters, Escalators, Moving Walks, Platform Lifts and Stairway Chairlifts]; and a change to Cables Under a Raised Floor of IT Equipment Rooms in Article 645, along with a thoroughgoing restructuring of Article 625 on EVs, including new provisions for bidirectional power transfer systems. This is followed by a look at eighteen changes to the two Articles that cover Swimming Pools, Fountains, and Natural and Artificially Made Bodies of Water, including new inspection protocols, a return of rules on underground wiring that had been eliminated, new provisions on Low-Voltage equipment and lighting, revised codes on electrically-powered pool lifts, and revised guidance on bonding and equipotential planes.
The class then surveys the 10 changes to PV System codes such as those for circuit sizing, OCPD, rapid shutdowns, means of isolating equipment, identification, and grouping. The final set of changes looked at include new Mating Connectors for PV Systems, new minimums before GFP rules apply to PV Systems, a vital new informational graphic on large-scale PV systems, revised labeling for Fuel Cell Systems, and new selective coordination guidance for fire pumps.
