Michigan Master Electrician License

What the Master License Requires

The master electrician credential is the highest individual license Michigan issues in the electrical trade. To qualify, you need all of the following:

• Age: At least 22 years old.
• Total experience: 12,000 hours of supervised practical experience over a minimum of six years.
• Post-journeyman hours: At least 4,000 of those hours must be completed after receiving your journeyman license, working under the supervision of an active master electrician.
• Active journeyman tenure: You must hold your Michigan journeyman license for at least two years before you can apply.

The math works out to roughly two additional years of full-time work after getting your journeyman credential, assuming you already met the 8,000-hour threshold for that license.

The Application

Submit a new BCC-341 application to LARA with notarized verification letters documenting your post-journeyman experience. The letters must come from employers where you worked under a master electrician's supervision -- the supervising master's license number and active status during the employment period are both verified.

This is where prior documentation habits pay off. If you've been collecting signed employer letters annually since your apprenticeship, you already have most of what you need. If you haven't, you're reconstructing years of work history under time pressure.

The PSI Master Exam

Format: 76 multiple-choice questions with a 180-minute time limit. Open-book, same approved references as the journeyman exam (2023 NEC, Michigan Electrical Code Rules Part 8, PA 407).

Passing score: 75%.

How it differs from the journeyman exam: The master test goes deeper into planning, designing, and supervising complex electrical installations. Expect heavier coverage of NEC Article 220 load calculations, service and feeder sizing, and the administrative rules governing contractor operations and permit requirements.

The same exam policies apply -- the NEC Handbook is prohibited (it's a different publication from the NEC itself), no custom tabs or loose papers, and your state documents must be bound with exactly three staples on the left edge. Two failures within two years triggers the same one-year lockout with mandatory remedial coursework.

Timeline: Journeyman to Master

The six-year figure is the minimum. The actual timeline can be longer depending on documentation and LARA processing. The bottleneck is rarely the exam itself -- it's making sure all 12,000 hours are documented to LARA's standards and that every supervisor's license was active during the periods you're claiming.

Why the Master License Matters

Beyond the higher earning potential (master electricians in Michigan earn roughly 15--25% more than journeymen), the master license unlocks two things a journeyman cannot do:

1. Qualify a contractor license: Every electrical contracting business in Michigan must designate a full-time, Michigan-resident master electrician as its qualifying professional. Without a master on staff, the business cannot hold a contractor license, and without a contractor license, it cannot pull permits or bid on jobs independently.

2. Supervise at the highest level: Masters can supervise both apprentices and journeymen, plan complex installations, and serve as the responsible party for code compliance on projects.

The Michigan Electrician License Guide covers the master application process in detail, including how to audit your post-journeyman hours, verify your supervisors' license histories, and prepare for the exam's expanded scope.
