Mississippi 10 Hour Professional Engineer Course on the 2020 NEC

This course is designed to provide you with 10 hours of continuing professional competency (CPC) required to renew your Professional Engineer license. It covers changes to the 2020 NEC for those who perform work within the electrical field.

First, 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 then 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.

Next, 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.

Lastly, chapter 8 is a stand-alone chapter that covers some of the most interesting technologies for data and communications  A video provides a useful overview of the substantial overhaul of this Chapter. 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.
