Current Michigan Master format: the PSI exam contains 76 questions, allows 180 minutes, requires 75% to pass and is open book. The active exam basis is the 2023 NEC with Michigan Electrical Code Rules Part 8 and applicable state laws.
What Is the Michigan Master Electrician Exam?
The Michigan Master Electrician examination is administered by PSI for the Michigan Department of Licensing and Regulatory Affairs, Bureau of Construction Codes. It tests advanced electrical code knowledge, electrical theory, calculations, state law and the additional planning and supervision knowledge expected at the Master level.
The exam covers grounding and bonding, overcurrent protection, wiring methods and installations, boxes and cabinets, services, feeders, motors and motor controls, special occupancies, load calculations, lighting, appliances, box and raceway fill, power-limited circuits, general trade knowledge and electrical theory.
Exam answer: 76 questions, 180 minutes, 75% passing score and open-book testing.
Code answer: the current Michigan and PSI exam basis is the 2023 NEC with Michigan Electrical Code Rules Part 8. Michigan is working on proposed 2026 NEC-based rules, but the current exam remains based on the 2023 NEC.
Contractor distinction: Michigan currently does not require a separate Electrical Contractor examination. A contractor license is a business credential requiring an associated Michigan Master Electrician responsible for code compliance.
The Master exam goes beyond the Journeyman level by adding knowledge required to plan and supervise electrical installations. That makes calculation accuracy, code navigation, system-wide planning and trade judgment especially important.
