This 4-hour training reviews some of the most significant updates introduced in the 2026 National Electrical Code (NEC), including revisions to industry terms, installation methods, and calculations.
Designed for busy industry professionals, the self-paced program is 100% online and self-paced.
Participants will learn about:
- Revisions involving equipment listing, identification markings, and working space standards
- Improvements to load calculation and protection rules for dwelling units, accessory buildings, EVSEs, and appliances
- Adjustments impacting wiring methods, conductor sizing, ampacity tables, and raceway applications
- Modified standards for wiring devices, switches, panelboards, and overcurrent protection systems
- Enhanced protocols for HVAC equipment, stationary batteries, and fixed outdoor electric heating equipment
- Updates involving hazardous locations, cannabis oil installations, marinas, and elevator systems
- New regulations for emergency systems, fire pumps, electric vehicle systems, and communications infrastructure
Upon completion, electricians will be able to recognize and successfully implement current NEC standards in the field.
