AR - 2023 NEC Changes: Chapters 4-7 (PGM)

Part one of this interactive online course covers updates made to general use equipment in the 2023 National Electrical Code. In this course, we’ll discuss revisions made to Articles 410, 422, 426, 430, 440, 445, 450, and 480. Notable changes include the addition of a new part to Article 410 addressing germicidal irradiation luminaires and new restrictions added to Article 440. Article 445 clarifies the requirements for the generator’s disconnecting means and reviews the signage requirements for the generator’s emergency shutdown device, and “transformer” is now defined and enforced through Article 450.

Part two covers some of the 2023 updates in the National Electrical Code, including changes to Articles 604, 625, and 680. We will be discussing manufactured wiring systems, electric vehicle power transfer systems, and swimming pools, fountains, and similar installations. These updates will help to keep you wired into the newest changes in the NEC.

Part three covers some of the 2023 updates in the National Electrical Code®, including changes to Articles 690, 705, 706, 722, 724, 726, 750, 760, and 810. We will discuss solar photovoltaic systems, energy storage systems, Class 4 fault-managed power systems, energy management systems, and more, so get charged up on updates to the NEC here.

Part four of this interactive online course covers changes to special occupancies in the 2023 National Electrical Code. Articles covered in this course include Articles 500, 502, 512, 517, 547, 555, and 590. Notable changes include the following items.
