This is a two-part course which covers the 2020 NEC Changes. Part One of this course covers the changes in Articles 411, 422, 424, 430, 440, 445, 450 and 480 of the National Electrical Code®. Article 411 contains the requirements for low voltage lighting. Article 422 covers appliances. Article 424 covers fixed electric space-heating equipment. Article 430 covers motors and their controllers. Article 314 covers air-conditioning and refrigeration equipment. Article 445 contains the requirements for generators. Article 450 covers transformers. Article 480 covers storage batteries. Notable changes include expanding the GFCI requirements for specific appliances, addressing new overload protection options for certain motors, new listing requirements for generators, and added disconnecting means requirements for generators and batteries.
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.
By the end of this course, you will be able to:
· Discuss when an assembly of listed parts are allowed for low-voltage lighting.
· List the appliances that require GFCI protection if they're rated 150 volts or less to ground and 60 amps or less.
· Recall the voltage threshold for appliances that require listing.
· Indicate when a thermostat can be used as a disconnecting means.
· Define electronically protected.
· Determine if a stationary generator should be listed or field labeled.
· Recall the requirements of emergency shutdown devices for generators and battery systems at dwelling units.
· Recall the rules for sizing and emergency generator.
· Identify the type of transfer switches that are not allowed for emergency systems.
· Recall the fire rating for a listed fire resistive cable system used in an emergency system.
· List the requirements of a DC micro grid if it's used as a power source.
· List the new requirements for transfer equipment.
· Identify how and whom is to install and maintain energy storage systems.
· Define cable bundle in Article 725.
