This 8-hour training explores major updates to the 2026 National Electrical Code (NEC) across Chapters 1 through 4, with a focus on practical, on-the-job application.
Learners will review revised definitions, code organization changes, and new requirements for equipment marking, working space, and load calculations.
Additional topics include:
- Updated rules for GFCI, AFCI, SPGFCI, and GFPE protection in dwelling and non-dwelling installations
- Branch-circuit, feeder, and service load calculations using revised dwelling-unit and EVSE rules
- Grounded and ungrounded conductor identification standards
- Revised wiring methods, including cable routing, physical protection, and underground installations
- Updated securing and supporting regulations for cables and conductors, including installations above suspended ceilings
- Conductor sizing and revised ampacity tables to support accurate installations
- New provisions affecting switches, wiring devices, panelboards, industrial control panels, and appliances
By the end, participants will be better prepared to navigate and apply key NEC revisions in daily work.
