Washington Electrician 2020 NEC Changes: 2 Hour Program #1

Part one of this two part course will briefly discuss the 2020 implementation of the National Fire Protection Association’s (NFPA) new revision process for considering changes to the National Electrical Code (NEC). You will be introduced to the 2020 NEC’s new articles covering Overvoltage Protection, Medium Voltage (MV) Cable, and Type P Cable. We’ll show you how and where the NFPA has reorganized and relocated articles to expand on Manufactured Buildings and Relocatable Structures.  Additionally, we’ll review the two articles that were merged into one to cover Marinas, Boatyards, Floating Buildings and Commercial and Noncommercial Docking Facilities. And finally, we’ll summarize the changes made to Article 800 General Requirements for Communications Systems.

Part two of this course covers the changes in Articles 700, 702, 706, 725, 770 and Chapter 8 of the National Electrical Code®. Article 700 contains the requirements for emergency systems. Article 701 covers optional standby systems. Article 706 covers energy storage systems. Article 725 covers Class 1, 2, and 3 remote-control, signaling, and power-limited circuits. Chapter 8 covers communications systems. Notable changes include clarification of the requirements for transfer equipment, reduced requirements for unit equipment used for emergency lighting, several new requirements for energy storage systems, and the consolidation of several rules in Chapter 8.
