The course consists of five segments.

Segment one briefly discusses the 2020 implementation of the National Fire Protection Association^® (NFPA^®) new revision process for considering changes to the National Electrical Code^® (NEC^®). You will be introduced to the 2020 NEC new articles covering Overvoltage Protection, Medium Voltage (MV) Cable, and Type P Cable.

Segment two walks you through some of the most recent changes concerning this live safety device, as well as review other changes associated with branch circuits. We will address changes to Chapter 2 Wiring and Protection, noting updates to Articles 100, 200, and 210.

Articles 404, 406, 408, and 410 of the National Electrical Code are covered in segment three. Articles 404 and 406 contain the requirements for switches and receptacles. Article 408 covers panelboards, switchboards, and switchgear. Article 410 covers luminaires, lampholders, and lamps.

Segment four 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.

The final segment is designed to give you an overview of Article 690 Solar Photovoltaic Systems, and Article 705, Interconnected Electrical Power Production Sources of the 2020 National Electrical Code® (NEC®). Notable changes in the articles for photovoltaic systems and interconnected electric power production sources include changes to PV overcurrent protection, disconnecting means, and language for interconnection of electric power production sources.
