Explore some of the most significant additions and reorganizations introduced in the 2026 National Electrical Code (NEC), and how they affect everyday installation practices and jobsite safety.
The 6-hour online training simplifies complex code updates into practical, easy-to-follow concepts.
You’ll learn how the revisions impact:
- Definitions and code organization
- Equipment listing, identification markings, arc-flash labeling, and working space standards
- Branch-circuit, feeder, and service load calculations for dwelling units and EV supply equipment
- Energy management systems, grounded conductor identification, and signaling circuits
- GFCI, SPGFCI, and ground-fault protection applications in residential and commercial settings
- Conductor sizing, ampacity tables, raceways, wiring devices, switches, and panelboards
- HVAC systems, generators, hazardous locations, marinas, EV systems, emergency power, and communications infrastructure
Upon successful completion, you’ll be prepared to interpret and apply the latest NEC standards across all your projects.
