Review selected updates in the 2026 National Electrical Code (NEC) affecting Chapters 2, 3, and 4, with emphasis on services, feeders, branch circuits, wiring methods, conductors, raceways, and wiring devices.
As you progress through the material, you’ll become familiar with the latest rules for:
- Service and feeder disconnection, equipment barriers, guarding methods, and overcurrent device placement
- Grounding and bonding methods for systems operating above 1000 volts, including parallel conductor installations
- Wiring method applications involving cable routing, support systems, physical protection, and environmental air spaces
- Raceway installations, underground wiring protection, bends, and temperature exposure considerations
- Conductor construction, identification, sunlight resistance, and ampacity table calculations for various installations
- Enclosures, splices, taps, feed-through conductors, and raceway-supported cabinet applications
- NM cable, fixture wires, wiring devices, and GFCI-protected replacement device installations
At the conclusion of the program, you’ll have a clear understanding of how the latest NEC additions and reorganizations impact your work and know how to implement them safely across all projects.
