This course is designed for all licensed electricians in Washington and fulfills all four of the required hours of continuing education (CE) on Washington Rule & Law. It is designed to complement 12 hours of class time on changes to Chapters 1-5 of the 2017 NEC and 4 hours of Washington Rule & Law for electricians in order to fulfill the entire 24 hours of CE that must be completed during this license renewal cycle.
Changes to the 2017 NEC Chapter 4 – Equipment for General Use and Chapter 6 – Special Changes to the 2017 NEC Chapter 6 – Special Equipment, Chapter 7 – Special Conditions, Chapter 8 – Communication Systems & Chapter 9 – Tables & Informative Annexes: This class presents every significant change made to Chapter 6 in the 2017 National Electrical Code® (NEC). This Chapter 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. This is followed by the most varied Chapter in the NEC, Chapter 7, including the provisions for such “special conditions” as emergency back-up systems, direct current microgrids, and optical fiber cable as well as the new Article on the vital and rapidly growing field of energy storage systems. Finally, every significant change to Chapter 8, addressing wiring methods for communication systems, and to Chapter 9 (Tables) as well as to the Informative Annexes are presented. The Tables and Informative Annexes all work together with the provisions of Chapters 1-4 to help an installer and designer use the NEC effectively.
Each change in this lesson on Chapters 6 through 9 is presented first with a “thumbnail” to help orient the student and provide a ready means for reviewing the material. The 2017 NEC language for the affected code is then provided, with any deletions and revisions from the 2014 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.
