Key revisions to the code include:

• New general criteria for all electrical systems, including a rule requiring level/flat surfaces within the working space for electrical equipment and expanded provisions covering the use and approval of reconditioned electrical equipment
• Changes impacting residential electrical systems, ranging from expanded ground-fault circuit interrupters (GFCI) requirements for specific appliances and new requirements for optional installation of receptacle outlets serving island and peninsular countertops and work surfaces
• Introduction of commercial/industrial electrical systems requirements for GFCI for special appliances, the use of replacement panelboards, and expansion of arc-fault circuit interrupter (AFCI) protection provisions
• Increased focus on alternative energy systems and emergency management, including revised requirements on the interconnection of distributed on-site power supplies with electric utility supplies, edits to Article 480 to delineate storage battery systems from energy storage systems (ESS), and new rules on commissioning of ESS
• New articles and requirements for never before covered systems and equipment such as Class 4 fault-managed circuits, hazardous locations within commercial and industrial cannabis production facilities, equipotential bonding in and around areas with splash pads, insulated bus pipe/tubular covered conductors systems, and more
