This 8-hour online class highlights the 2026 National Electrical Code (NEC) revisions that influence system layout, equipment installations, and protection methods in residential and commercial applications.
The material focuses on the updates to Chapters 1 through 4, from branch-circuit calculations to conductor routing methods.
Topics covered throughout the training include:
- Revised NEC definitions, code arrangement updates, and equipment labeling provisions
- Working space dimensions, “in-sight-from” rules, and arc-flash safety markings
- Energy management systems, EVSE load calculations, and service sizing methods
- GFCI/SPGFCI applications, AFCI provisions, and grounding and bonding practices
- Conductor ampacity tables, cable support rules, underground installations, and raceway systems
- Wiring devices, industrial control panels, appliances, and fixture wire installations
Participants will become equipped to interpret and integrate the latest NEC standards effectively in the field.
