2026 NEC® Changes: Code-Wide Changes, New and Deleted Articles, and Definitions

The 2026 NEC® represents one of the most significant structural transformations in electrical code history, setting the stage for an unprecedented 22-chapter format coming in 2029. This comprehensive course explores the major code-wide changes including the reorganization of requirements into three distinct categories, new and relocated articles, such as load calculations moving from Article 220 to Article 120, and critical new definitions. Participants will gain essential knowledge of how Chapter 8 now integrates with Chapters 1-7, understand the differences between energy storage systems and power control systems, and master new GFCI classifications that will impact electrical installations across all sectors.
