ABOUT THE TOPIC:
The 2023 National Electrical Code (NEC) is the latest version of electrical code issued by the NFPA. This program has been developed to review the new content within the 2023 NEC and differences from the previous 2020 NEC, in such a way so that the material learned can be applied immediately with increased proficiency, safety and efficiency. Specific areas within the 2023 NEC with substantial changes include:
• Residential Electrical Systems: Addresses ground-fault circuit interrupters (GFCI) for specific appliances, emergency disconnects, 10-ampere branch circuits, and more.
• Commercial and Industrial Electrical Systems: Includes requirements for the use of “replacement panelboards,” arc-fault circuit interrupter (AFCI) protection, disconnecting means in sight of luminaires using double-ended lamps to include the LED type, and other considerations.
• Alternative Energy Systems and Energy Management: Addresses the interconnection of distributed on-site power supplies with electric utility supplies, the delineation between storage battery, emergency storage, and photovoltaic electric systems, and more.
• Never-before Covered Systems and Equipment: Covers Class 4 fault-managed circuits, hazardous locations in commercial and industrial cannabis production facilities, equipotential bonding in areas with “splash pads,” and other requirements
