Explore critical updates to Sections 100 through 406 of the 2026 National Electrical Code (NEC) in this 8-hour online program.
Emphasizing safety, system performance, and proper installation techniques, the material covers:
- Modifications regarding grounding and bonding protocols, feeder calculations, and service load calculations
- Updated procedures for systems operating at and above 1000 volts
- Adjusted GFCI, AFCI, SPGFCI, and GFPE protection standards for residential and commercial installations
- Revisions affecting cable routing, physical protection standards, and underground installations
- Guidance for NM cable, conduit systems, and raceway-supported enclosures
- Revised conductor sizing, ampacity tables, and cable support methods
- New code arrangements and Article definitions
After finishing the training, learners will be ready to apply the latest NEC standards across a wide range of projects.
