Review 2026 updates affecting Chapters 2 through 4 of the National Electrical Code (NEC).
The 4-hour online training emphasizes practical code applications that influence system layout, conductor protection, equipment placement, and overall installation performance in modern systems.
Topics include:
- Service disconnecting means, feeder installations, and guarding methods for energized equipment
- Grounding and bonding provisions for systems rated above 1000 VAC and 1500 VDC
- Physical protection methods for conductors, raceways, and cable assemblies
- Securing and supporting conductors above suspended ceilings and throughout raceway systems
- Raceway temperature exposure limits, bend allowances, and underground installation practices
- Conductor sizing methods, ampacity adjustments, and sunlight-resistant cable applications
- Nonmetallic-sheathed cable installations, fixture wire applications, and device replacement standards
Participants emerge ready to apply revised NEC standards effectively in both residential and commercial environments.
