2026 NEC Changes: Overcurrent Protection, Overvoltage Protection, and Grounding and Bonding
What if a simple drywall screw holding a grounding bar could create a deadly code violation that most electricians never realize they’re making? Join NEC expert and Code-Making Panel member Ryan Jackson as he reveals the most impactful changes in the 2026 National Electrical Code, from the first-ever specification of allowable overcurrent protective device types to revolutionary new rules for grounding electrode conductor splicing. This essential course will equip you with the knowledge to navigate new medium voltage listing requirements, properly install surge protective devices, and avoid costly mistakes when working with mixed metallic and non-metallic electrical systems.
