Colorado 8 Hour 2020 NEC Chapters 6 & 7

This course satisfies 8 Code Change hours for the Colorado Electrical license renewal.

This class presents every significant change made to Chapters 6 and 7 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. Chapter 7 governs every condition that requires special considerations when it comes to electrical installations.

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.

This class next presents 29 significant changes to Chapter 7 “Special Conditions”, the most varied Chapter in the NEC. This portion of the class begins with 7 changes to the Articles on Emergency Systems and Optional Standby Systems, including guidance on incorporating alternative power sources. This is followed by 13 changes to Articles 705 & 706, including a complete overhaul of Article 705 on Interconnected Electric Power Production Sources and new maintenance and identification protocols for Energy Storage Systems. The class finishes up with a wide range of wiring systems adapted to special purposes, including a revision of Transfer Switch rules for Critical Operations Power Systems (COPS), updates to Articles 710 on Stand-Alone Systems and DC Microgrids; clarifications on the Use of Class 1, Class 2, and Class 3 Remote-Control Signaling and Power-Limited Circuits, and three changes to Article 770 on OFC: Mechanical Execution of Work, Cable Routing Assemblies and Cable Trays, and Installation in Enclosures shared with energized conductors.
