Modern installations rely on proper conductor protection, reliable wiring methods, and equipment that meets evolving performance standards.
This 6-hour online training examines important 2026 National Electrical Code (NEC) revisions to Chapters 3 through 5 affecting these projects, including specialized occupancies.
Participants will review updates related to:
- Wiring methods, cable routing practices, and protection for conductors exposed to physical damage or environmental conditions
- Raceway systems, cable support methods, bending limitations, and revised installation standards for NM and tray cable
- Conductor sizing methods, ampacity adjustments, identification practices, and enclosure applications
- Wiring devices, switches, panelboards, motors, HVAC equipment, generators, batteries, and fixed heating systems
- Hazardous location classifications and updated protection methods for flammable or high-risk environments
- Health care occupancies, marinas, docking facilities, recreational vehicles, and floating structures
- Electric vehicle power transfer systems and other specialized installations are covered throughout Chapters 4 and 5
The class prepares professionals to apply updated NEC standards more effectively across residential, industrial, and specialty environments.
