What Is MN-ME Certification?
MN-ME refers to the Minnesota Master Electrician License Exam, the credentialing test that Minnesota's Class A Master Electrician license is built around. In the Minnesota Department of Labor and Industry's (DLI) examination guide, this exam is designated "AM." Passing it is the gateway to holding a personal master electrician license in Minnesota - a license that is legally distinct from an electrical contractor business license. Contractors need a business license to operate; individuals who design, supervise, and take responsibility for electrical work need the personal master license, which is what the MN-ME exam qualifies you for.

Who Governs the Exam
The Minnesota Department of Labor and Industry administers the MN-ME exam directly, working alongside the Minnesota Board of Electricity, which sets policy and reviews outcomes such as pass-rate data. Unlike some trades where a third-party testing vendor runs the show, DLI itself handles the examination guide, application processing, approval, and scheduling. That means every rule about eligibility, fees, and retesting comes from a single authoritative source rather than a patchwork of vendor policies.
Eligibility Routes
Before you can sit for the MN-ME exam, DLI requires proof that you meet one of several eligibility paths. You must apply with documentation and receive approval before you're allowed to schedule a test date.
- Electrical engineering degree from an accredited college or university.
- One year of work as a licensed journeyworker electrician.
- Five years of practical experience in planning, laying out, supervising, and installing electrical wiring, apparatus, or equipment.
Each path requires supporting documentation submitted directly to DLI. For a full breakdown of what paperwork each route needs and common approval pitfalls, see MN-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Application, Fees, and Scheduling
The application and examination fee is $50, covering both the review of your eligibility documents and your seat at the exam. Once DLI approves your application, you schedule your test date. If you don't pass, DLI requires a 30-day waiting period after your failure notice before you can apply to retest - plan your study calendar with that gap in mind rather than assuming you can retest immediately.
Key Takeaway
Submit your eligibility documentation early. Approval has to happen before scheduling, so delays in paperwork directly delay your test date - and if you fail, the mandatory 30-day wait compounds any scheduling lag.

Exam Format and Materials
The MN-ME exam consists of 80 questions, with a 5-hour-30-minute time limit and a 70% passing requirement. Questions are written multiple-choice, and the format includes:
- Standard single-answer multiple-choice items.
- Electrical calculation problems.
- Items requiring more than one correct answer to be marked correct.
Every question carries equal point value. Partial credit is not awarded unless a specific question states otherwise - so a multi-answer item is scored as right or wrong as a whole in most cases, not proportionally. This matters for pacing: guessing on part of a multi-select question without reasoning through every option can cost you the full point value of that question.
The exam is open-book, but only with DLI-provided materials. You'll be given an untabbed softcover NEC, the applicable Minnesota Laws and Rules Booklet, and a basic calculator. Personal reference materials, tabbed codebooks, and electronic devices are prohibited. This means your NEC navigation skill - not your ability to bring pre-marked tabs - is what gets tested.
The 11 Exam Domains
DLI's examination matrix organizes content into 11 domain areas that mirror the structure of the National Electrical Code itself, plus an applied theory domain. Understanding what each domain actually covers - not just its title - is the difference between generic exam prep and targeted MN-ME prep.
Domain 1: Introduction
Covers the NEC's scope, purpose, and organizational structure - the foundational article that explains how the rest of the code is arranged.
- Purpose and scope statements
- Mandatory vs. permissive language
Domain 2: Chapter 1 General
Definitions and general requirements that apply across every other chapter - this domain underpins correct interpretation everywhere else in the code.
- Key definitions candidates must know cold
- General installation requirements
Domain 3: Chapter 2 Wiring and Protection
Branch circuits, feeders, overcurrent protection, and grounding/bonding - one of the heaviest-tested chapters on any master-level NEC exam.
- Grounding and bonding rules
- Overcurrent protection sizing
Domain 4: Chapter 3 Wiring Methods and Materials
Covers conductor types, raceways, boxes, and installation methods - heavily calculation- and table-dependent material.
- Conduit and cable installation rules
- Box and conductor fill calculations
Domain 5: Chapter 4 Equipment for General Use
Motors, appliances, luminaires, and general equipment requirements found across residential and commercial work.
- Motor circuit sizing and protection
- Luminaire and appliance provisions
Domain 6: Chapter 5 Special Occupancies
Hazardous locations, health care facilities, and other occupancy-specific rules that deviate from general requirements.
- Classified/hazardous location basics
- Occupancy-specific exceptions
Domain 7: Chapter 6 Special Equipment
Signs, elevators, solar photovoltaic systems, and other equipment categories with their own dedicated articles.
- Solar/PV system requirements
- Equipment-specific disconnect rules
Domain 8: Chapter 7 Specific Conditions and Systems
Emergency systems, standby power, and fire alarm circuits - critical-life-safety installation requirements.
- Emergency and standby system separation
- Fire alarm circuit provisions
Domain 9: Chapter 8 Communication Systems - Outside and Entering Buildings
Communications circuits and their required separation and protection when entering a structure.
- Separation from power conductors
- Entrance protection requirements
Domain 10: Chapter 9 Tables
The NEC's reference tables - conductor fill, ampacity, and conduit sizing tables that calculation questions depend on directly.
- Ampacity table lookups
- Conduit and tray fill tables
Domain 11: Applied Electrical Theory, Electrical Systems and Equipment
Practical application of Ohm's Law, power calculations, and system design concepts beyond rote code lookup.
- Voltage drop and load calculations
- Applied theory in real installation scenarios

2026 NEC Transition
A critical date for anyone scheduling their MN-ME exam in 2026: examinations taken on or after September 8, 2026 use the 2026 National Electrical Code. This exam-content transition is separate from the August 17, 2026 installation-code effective date - meaning the code cycle that governs actual field installations changes on a different timeline than the code cycle tested on your exam. Candidates scheduling near this window should confirm which NEC edition their specific test date will use before finalizing study materials.
Pass Rate Context
According to the Minnesota Board of Electricity's April 14, 2026 minutes, 2026 year-to-date master pass rates stood at 44.7% by total examinations and 47% by test taker. These two figures use different denominators - one counts every exam sitting, the other counts unique candidates - and both predate the September 2026 NEC transition, so they reflect performance under the prior code edition. Treat these as directional context rather than a guarantee of how future testing windows will perform.

Building a Study Plan Around the Domains
Rather than studying the NEC cover to cover in article order, allocate time by domain weight and personal weak points. Chapters 2 and 3 (Domains 3 and 4) tend to demand the most calculation practice, while Domain 10's tables underpin questions scattered across nearly every other domain - so reviewing table navigation early pays off throughout your entire prep window.
Foundations
- Domain 1 and Domain 2: scope, definitions, general requirements
- Practice untabbed NEC navigation daily
Core Wiring Chapters
- Domain 3 (Chapter 2) and Domain 4 (Chapter 3): grounding, overcurrent protection, conductor fill
- Pair every rule with a Domain 10 table lookup
Equipment and Special Topics
- Domains 5, 6, and 7: general equipment, special occupancies, special equipment
- Timed practice sets with multi-answer questions
Systems and Applied Theory
- Domains 8, 9, and 11: life-safety systems, communications, applied calculations
- Full-length timed practice exam under 5.5-hour conditions
This isn't a generic study template - it's sequenced to match how heavily each domain leans on the ones before it, which is why Domain 10's tables are introduced early rather than left for the end.

After You Pass: Licensing and Renewal
Passing the MN-ME exam gets you the personal Class A Master Electrician license, but licensing doesn't stop there. Master licenses expire on the last day of February in odd-numbered years, so your renewal cycle is fixed to that calendar regardless of when you originally passed. Renewal costs $93 and requires 16 hours of approved continuing education per two-year period, with at least 12 of those hours specifically on the NEC.
| Item | Detail |
|---|---|
| Application/Exam Fee | $50 |
| Passing Score | 70% |
| Exam Length | 80 questions, 5 hours 30 minutes |
| Retest Wait | 30 days after failure notice |
| License Expiration | Last day of February, odd-numbered years |
| Renewal Fee | $93 per two-year period |
| Continuing Education | 16 hours total, 12+ on NEC |
