WA - 2026 NEC Changes: Wiring Methods & Equipment (PGM)
Course Description
This course provides a focused review of 2026 National Electrical Code changes related to electrical enclosures, wiring methods, and general-use equipment. Learners will examine how the Code governs the installation and use of boxes, cabinets, meter socket enclosures, conduit bodies, fittings, handhole enclosures, raceways, cables, support hardware, and cable trays. Topics include service conductors in enclosures, ceiling fan box ratings, wiring accessibility, listed support hardware, MC and NM cable applications, cable bending radius, dissimilar metal contact, RMC and IMC terminations and fittings, nonmetallic raceway sizing, and cable tray clearance requirements.
The course also covers general-use equipment requirements, including revised scopes for Articles 404 and 406, wiring device termination rules, GFCI protection for replacement receptacles, prohibited locations for upward-facing receptacles, park and recreation area requirements, and field marking requirements for switchboards, switchgear, panelboards, and motor control centers. Additional topics include central heating equipment circuiting, conductive pavement heating systems, new motor design types, adjustable speed drives, and listing requirements for medium-voltage switchgear and industrial control assemblies.
By the end of the course, learners will be prepared to apply updated 2026 NEC requirements for enclosure, wiring method, and general-use equipment installations in a safe and code-compliant manner.
