2026 NEC® Changes: Load Calculations
This comprehensive course explores the significant changes to load calculations in the 2026 National Electrical Code (NEC), providing electrical professionals with essential knowledge of updated requirements that will shape electrical design and installation practices. Participants will master fundamental concepts including energy management systems and power control systems, understand the expanded scope of Article 120, and learn the critical reasoning behind calculating continuous loads at 100 percent.
The course covers residential calculation methods in detail, including determining minimum circuits for dwelling units, calculating loads for clothes dryers and fixed multi-outlet assemblies, applying reduced lighting calculations, and understanding Electric Vehicle Supply Equipment (EVSE) load calculation requirements. These skills position learners to handle the most common electrical projects with confidence and code compliance.
Advanced calculation methods and specialized applications prepare participants to tackle complex projects across diverse settings. Coverage includes the optional calculation method for dwellings, simplified rules for existing installations, and revised multifamily dwelling requirements to efficiently manage residential projects of any scale. The course also reviews specialized load calculations for health care facilities, RV parks, and mobile home parks, expanding professional capabilities to serve a broader range of clients and project types.
Upon completion, participants will have the updated 2026 NEC load calculation requirements as part of their professional toolkit, enabling them to deliver accurate, compliant electrical designs that meet the evolving demands of the electrical industry.
