  • 8 Hour Course
  • $80.00

This class presents every significant change made to Chapters 4 and 6 in the 2020 National Electrical Code® (NEC-2020), the two Chapters that address electrical equipment. Chapter 4 is one of the “core” Chapters in the NEC. It 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. 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 begins with 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;
  • Tamper-Resistant Receptacles;
  • Single-Pole Separable Connectors;
  • Methods of Grounding Luminaires;
  • GFCI for Appliances;
  • Electronically Protected Motor Circuits and Controllers;
  • Emergency Shutdown in One- and Two-Family Dwelling Units;
  • Transformers and Transformer Vaults; and 
  • Permissibility of Retrofit Trip Units for Equipment Over 1000 Volts Nominal.

The second half of 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.
