Power distribution systems, conductor installations, and wiring methods continue to evolve with each code cycle.
This 5-hour online program examines important 2026 National Electrical Code (NEC) revisions across Chapters 2, 3, and 4, helping participants understand how updated installation standards affect system performance and jobsite safety.
Key discussion areas include:
- Disconnecting means, feeder installations, service equipment location rules, and barrier placement standards
- Overcurrent device provisions and grounding methods for higher-voltage systems and parallel installations
- Protection against physical damage, cable support methods, and routing practices above suspended ceilings
- Raceway applications involving underground installations, environmental air spaces, bends, and temperature exposure
- Conductor identification methods, sunlight resistance, ampacity adjustments, and sizing calculations
- Enclosures, splices, taps, feed-through conductors, and permitted uses of NM cable, conduit systems, and PVC
- Device mounting standards, fixture-wire applications, and replacement devices protected by GFCI technology
Professionals gain the ability to interpret and apply updated NEC installation standards more effectively across residential, industrial, and commercial environments.
