Michigan master electrician exam: format, NEC edition and fee
Michigan licenses master electricians through the Bureau of Construction Codes in the Department of Licensing and Regulatory Affairs (LARA), and PSI runs the exam. These facts come from PSI's Michigan electrical bulletin (effective 8/20/2026) and LARA's PSI exam page, read on 8 November 2026. Michigan sets its own rules and can change them, so confirm with LARA and the bulletin before you book.

What it covers
Michigan publishes a topic list without item counts: grounding and bonding, overcurrent protection, wiring methods, boxes and cabinets, services, feeders, motors and controls, special occupancies, load calculations, lighting, appliances, box and raceway fill, power-limited circuits, trade knowledge and theory. The master exam also covers the knowledge needed to plan and supervise installations, plus Michigan's licensing act, its rules and the Michigan electrical code rules. Our master exam outline maps the NEC topics into the twelve areas states share.
