- The test is 100 multiple-choice questions in 4 hours, open-book, with a 70% passing score.
- Wiring Methods & Materials (24%) and Wiring & Protection (19%) together make up 43 of the 100 questions.
- Candidates must use the softcover 2023 NEC only - the hardcover NEC Handbook is banned from the testing room.
What Is the ME-ME Certification?
The ME-ME - the Maine Master Electrician License Exam - is the credentialing test that stands between a qualified Maine journeyman and a master electrician license. It is not a generic national trade credential; it is a state-specific licensing exam tied directly to Maine statute and to the Maine Electricians' Examining Board's rules on code editions, study hours, and renewal cycles. If you've searched broader questions like What Is ME-ME? or ME-ME Meaning, this article narrows the focus specifically to the master-level licensing exam and what makes it different from journeyman or apprentice testing.
Passing the ME-ME signals that a candidate can plan, supervise, and take responsibility for electrical installations at the highest level Maine licenses in the trade. It is a closed professional gate: you cannot simply register and take the test. You must first satisfy hour-based eligibility requirements and get Board approval before a test date is even scheduled.
Who Issues It and Who Administers Testing
The credential itself is issued by the Maine Electricians' Examining Board, which operates under the state's Office of Professional and Occupational Regulation. The Board sets the eligibility rules, the required study hours, and the code edition tested. Actual test delivery - scheduling, proctoring, and scoring - is handled by Prov, the third-party testing vendor.
This split matters practically: the Board decides who is allowed to test and what content is fair game, while Prov controls how and where you actually sit for the exam, including the availability of physical test centers versus remote Examroom delivery.
Exam Format and Question Style
The ME-ME is a computer-based, multiple-choice, open-book examination. Candidates answer 100 questions in 4 hours, and a passing result requires a score of 70%. Because it's open-book, the exam is less about pure memorization and more about knowing exactly where to find the right code section quickly under time pressure - a skill that's very different from studying for a closed-book test.
The book allowed is the softcover 2023 NEC specified by the Board-linked May 8, 2026 bulletin (revision MOPOR-2026.04.17). The hardcover NEC Handbook, with its extra commentary, is explicitly prohibited - only the plain code book is permitted. Note that Maine's separate adoption of the 2026 NEC for actual field installations, effective July 1, 2026, does not change what's tested on the exam itself; the exam reference stays the 2023 NEC.
Key Takeaway
Bring the softcover 2023 NEC only. Tabs, handwritten notes, highlighting, and underlining inside that approved book are allowed - but nothing may be added or inserted (no printed inserts, sticky notes with content, or extra pages).
Test-day essentials are straightforward: a simple four-function calculator is permitted (no scientific or programmable models), and you must bring current government-issued photo identification.

The 10 ME-ME Exam Domains
The exam draws its 100 questions from ten content domains, each with a set percentage weight. Understanding these weights is the single most important planning input for your study time, because two domains alone account for nearly half the test.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Wiring Methods & Materials | 24% | 24 |
| Wiring & Protection | 19% | 19 |
| General Electrical Knowledge | 15% | 15 |
| Equipment for General Use | 15% | 15 |
| Special Equipment | 7% | 7 |
| Special Occupancies | 6% | 6 |
| Service Feeders and Branch Circuits | 4% | 4 |
| Motors & Controls | 4% | 4 |
| Special Conditions | 4% | 4 |
| Communication Systems | 2% | 2 |
Wiring Methods & Materials (24%) and Wiring & Protection (19%)
These two domains together make up 43 of the 100 questions - nearly half the exam. Candidates should master conductor sizing, raceway and cable installation rules, overcurrent protection, grounding and bonding, and box/enclosure fill calculations, since these areas repeat across both domains in different question framings.
- Know how to navigate NEC tables under time pressure - these two domains reward speed with the open book, not just knowledge.
- Practice locating grounding/bonding and overcurrent protection articles without hesitation.
General Electrical Knowledge & Equipment for General Use (each 15%)
Together these add another 30 questions. Expect coverage of fundamental definitions, general requirements, and equipment provisions that apply broadly across installation types - the kind of foundational material that supports correct interpretation of the heavier wiring domains above.
The remaining six domains - Special Equipment, Special Occupancies, Service Feeders and Branch Circuits, Motors & Controls, Special Conditions, and Communication Systems - are individually lighter but still appear on every test. For a full breakdown of each domain's likely question topics, see ME-ME Exam Domains 2026: Complete Guide to All 10 Content Areas.
Eligibility Routes to Sit for the Exam
You cannot register for the ME-ME on demand. The Board requires proof of one of several eligibility paths before it will approve you to schedule a test date:
- 12,000 hours as a licensed helper/apprentice, plus 576 hours of approved study
- 4,000 journeyman hours, plus 576 hours of approved study
- 6,000 journeyman-in-training hours, plus 576 hours of approved study
- Board-accepted comparable qualifications, evaluated case-by-case
On top of the hour requirement, licensing requires completion of a 45-hour NEC course finished within the two years immediately before you apply. Board approval must come before scheduling - you don't book a Prov appointment first and sort out eligibility later. For the complete rundown of documentation and timing, see ME-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Scheduling, and Test-Day Logistics
Budgeting for the ME-ME involves more than one line item. The exam fee itself is $90, paid to sit for the Prov-administered test. Separately, the initial master license carries a $150 fee plus $21 for the required criminal-history report - costs that apply after you pass, when you actually apply for licensure. A full cost breakdown, including renewal, is covered in ME-ME Certification Cost 2026: Complete Pricing Breakdown.
Test delivery happens either at a physical Prov test center or remotely through Examroom, giving candidates in different parts of Maine some flexibility in how they sit for the exam. If your plans change, you must cancel or reschedule at least three business days before your scheduled test - missing that window can cost you the appointment and the fee. Scheduling windows and deadlines are detailed further in ME-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
After You Pass: Licensing and Renewal
Passing the exam is only the qualifying step - you still apply for the actual master license, paying the $150 fee plus the $21 criminal-history report charge noted above. Once issued, the license is valid for two years, and renewal costs $150.
Staying current also means completing the Board-required 15-hour NEC update course for each three-year code cycle, keeping your knowledge aligned as Maine periodically adopts new NEC editions for field installations (as with the 2026 NEC taking effect for installations on July 1, 2026, separate from whichever edition the exam itself references at any given time).
Who Actually Needs the ME-ME
The master license unlocked by this exam is generally sought by electricians who want to take on supervisory responsibility, pull permits under their own name, or run their own electrical contracting operations rather than working solely under someone else's master license. Employers hiring for lead electrician, foreman, or business-owner-operator roles in Maine typically look for this credential specifically, not a generic multi-state electrical certificate.
If you're weighing whether pursuing the master license is worth the hour requirements and course costs relative to staying at journeyman level, the qualitative trade-offs - more responsibility and independence versus more upfront licensing effort - are explored in Is the ME-ME Certification Worth It? Complete ROI Analysis 2026. Career and earnings context specific to license level is covered separately in ME-ME Salary Guide 2026: Complete Earnings Analysis, and general job-market notes are in ME-ME Jobs.
A Domain-Aware Approach to Preparing
Because Wiring Methods & Materials and Wiring & Protection alone cover 43% of the exam, the most efficient study sequence front-loads those two domains before moving to lighter-weighted areas. A simple domain-weighted schedule looks like this:
Wiring Methods & Materials
- Drill raceway, cable, and box-fill rules using only the softcover 2023 NEC
- Practice locating tables quickly since the exam is open-book but timed
Wiring & Protection
- Focus on grounding, bonding, and overcurrent protection scenarios
- Time yourself answering practice questions to simulate the 4-hour limit
General Electrical Knowledge & Equipment for General Use
- Review foundational definitions and general equipment provisions
- Connect these back to wiring-domain questions for cross-reinforcement
Remaining Six Domains + Full Simulation
- Cover Special Equipment, Special Occupancies, Service Feeders and Branch Circuits, Motors & Controls, Special Conditions, and Communication Systems
- Run a full 100-question, 4-hour timed practice test with the approved book only
Spaced repetition and short focused review blocks can help retain code-table locations across weeks, but the scheduling logic above only works because it's anchored to the ME-ME's actual domain weights - not a generic study template.
