This course provides a focused review of foundational changes and general requirements introduced in the 2026 National Electrical Code. Learners will examine code-wide updates, new and deleted articles, revised Article 100 definitions, and the role of specific permission throughout the Code. The course also explains how NEC chapters function together as an integrated system and addresses key concepts such as energy storage systems, power control systems, interconnection equipment, GFCI types, receptacle outlets, and wiring devices.

The course also reviews important updates to general installation requirements that affect labeling, servicing, working space, equipment markings, short-circuit current ratings, and compliance. Topics include the removal of Annex J, the relationship between NEC requirements and manufacturer product instructions, connections of dissimilar metals, high-leg delta markings, revised arc-flash labeling, equipment servicing, reconditioning, the definition of “within sight,” and general requirements for connections over 1,000 volts.

By the end of the course, learners will be prepared to interpret and apply key 2026 NEC foundational and general requirement changes in real-world electrical installations.
