About the Minnesota Master Electrician license
Minnesota licenses electricians through the Department of Labor and Industry (DLI), under code and licensing rules set by the Minnesota Board of Electricity. The Class A Master Electrician is the senior individual credential, and the exam adds heavier load-calculation, design, and code-application content than the journeyworker exam. Unlike some states, Minnesota does not require you to already hold a journeyman license first — you qualify for the master exam through any one of three paths: a degree in electrical engineering from an accredited college or university, at least one year of experience as a licensed journeyworker electrician, or at least five years of experience in planning, laying out, supervising, and installing, which the experience page states as a 60-month total with category minimums. A holder at this level can typically pull permits, supervise journeymen and apprentices, design installations, and serve as the qualifying individual for a licensed contracting business.
The exam is National Electrical Code (NEC) based, because the examination guide uses the National Electrical Code edition adopted for the license questions. The references are supplied, not brought: the exam is administered directly by DLI (not by a third-party testing vendor), and DLI provides a soft-cover copy of the adopted NEC, a Laws and Rules Booklet, and a basic calculator at the testing site. That provided code book has no tabs, highlighting, or other aids — you may not bring your own code book, tabs, notes, study guides, or any personal reference materials into the exam room. So build your tabbing habit into your personal study copy only, to learn where things live fast, then spend your final prep weeks practicing the same lookups in a clean, untabbed book (using only the built-in table of contents and index) so you're not thrown off on test day, because the exam is as much a test of how fast you can locate a section as it is of what you have memorized.
Know these scope facts cold, because the exam asks them in plain-language form: the license is held by the individual, not the company; most installations require a permit and inspection before concealment (rough-in) and again at final; you must work within the classification you hold; and performing electrical work without the required license, or beyond your scope, is a violation that can cost you the license and carry civil penalties.
How Minnesota licensing works
- Experience: qualify with an accredited electrical engineering degree, at least one year as a licensed journeyworker electrician, or at least 60 months of documented, categorized experience (planning, laying out, supervising, wiring/installing, maintaining/repairing, and related work) under DLI's experience rules — a journeyman license is not a prerequisite.
- Education: a degree in electrical engineering from an accredited college or university is one path to the master exam; a two-year, department-approved technical college program instead credits toward the journeyworker/maintenance-electrician experience requirement, not the master path.
- Application: submit the application, fees, and proof of experience (often signed off by a supervising/master electrician or employer) to DLI; your application must be approved before you can schedule an exam date.
- Exam administration: DLI administers the exam directly at its office (not through a third-party vendor) — 80 questions, 5½ hours, 70 percent passing score. Only the department-provided NEC copy, Laws and Rules Booklet, and calculator may be used; no personal materials or phones are allowed in the building.
- Renewal: the Master Electrician license expires on the last day of February of each odd-numbered year and requires 16 hours of continuing education per cycle, at least 12 of which must relate to the NEC.
Before you rely on any value in this guide, confirm the currently adopted NEC edition on DLI's electrical codes and standards page and the current Electrical License Examination Guide. Ampacities, GFCI/AFCI scope, working-clearance distances, and receptacle-spacing rules all change between editions, and the exam is written to the edition adopted at the time you test — not necessarily the newest one published.
