This 16-hour comprehensive course provides an in-depth analysis of the 2026 National Electrical Code (NEC), specifically designed for electrical professionals seeking to renew their Wyoming electrical license
Course Description
Provides an in-depth analysis of the 2026 NEC structural reorganization, beginning with the migration of foundational wiring methods and advancing through the grounding and bonding standards for high-voltage systems. Participants will examine specific code changes regarding the relocation of securing and supporting rules, the restructuring of underground conductor requirements, and the “Great Migration” of medium-voltage services. The course further explores critical safety requirements for GFCI and AFCI protection across diverse environments, including outdoor HVAC outlets, dormitories, and dwelling unit kitchens. Specialized modules cover complex infrastructure such as EVSE load management, rapid shutdown initiation for PV systems, and the comprehensive consolidation of limited-energy and communication system articles within the new Chapter 7 framework.
Learning Objectives
-
Identify key changes in the relocation of general requirements, including new terminal identification standards and revised Arc-Flash labeling protocols.
-
Understand rigorous grounding and bonding requirements for high-voltage systems, bonding jumpers, and standardized bonding in hazardous locations.
-
Master the implementation of protection standards for modern infrastructure, including EVSE emergency shutoffs, dwelling unit load calculations, and AFCI retrofit flexibility.
-
Navigate specialty articles involving solar photovoltaic systems, distributed energy resources in healthcare facilities, and the reorganized communication cable application tables.
