What NH-ME Actually Is
NH-ME stands for the New Hampshire Master Electrician License Exam. It's the credentialing test that licensed journeyman electricians in New Hampshire must pass to move up to master status - the level required to pull permits independently, supervise crews, and legally run electrical work as a business owner or lead contractor in the state.
Unlike a training certificate or a voluntary industry credential, NH-ME is a regulatory gate. You don't get to skip it by having years of experience alone, and passing it doesn't automatically make you licensed - it's one required step inside a larger licensing process defined by New Hampshire administrative rule. If you're trying to understand exactly what the letters mean and where they come from, our companion piece on NH-ME Meaning breaks down the terminology, and What Does NH-ME Stand For? covers the naming in more detail.
Who Administers and Scores the Exam
The exam is overseen by the New Hampshire Electricians' Board, which sits under the state's Office of Professional Licensure and Certification. Actual test delivery - scheduling, proctoring, and scoring - is handled by Prov, the third-party testing vendor. This matters practically: your eligibility approval comes from the Board, but your test appointment, candidate information bulletin, and day-of logistics come from Prov.
Because Prov publishes its own candidate bulletins periodically, small details like referenced code editions can shift between bulletin releases even though the underlying 126-question domain structure stays the same. We cover this quirk in more depth in the code-edition section below and in NH-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Who Needs NH-ME and Who Hires For It
NH-ME is relevant to a fairly specific population: New Hampshire journeyman electricians who want to legally operate as masters - pulling their own permits, signing off on installations, running their own electrical contracting business, or supervising apprentices and journeymen on a jobsite without another master's direct oversight.
Employers who hire specifically for master-licensed electricians tend to be:
- Electrical contracting firms that need a licensed master of record to pull permits
- Property management and facilities companies needing in-house licensed supervision
- Electricians launching their own contracting business
- Larger commercial/industrial contractors that require master-level sign-off on complex service and feeder work
If you're weighing whether the license is worth the time and cost investment relative to staying a journeyman, that comparison is covered separately in Is the NH-ME Certification Worth It? Complete ROI Analysis 2026 and NH-ME Salary Guide 2026: Complete Earnings Analysis.
Exam Format, Fees, and Scheduling Mechanics
NH-ME is a computer-based, four-option multiple-choice, open-book examination. Candidates get 126 questions and 5 hours to complete them, with a required passing score of 70%. Open-book means you're allowed reference materials during the test - but only specific, approved ones (more on that below), so "open-book" doesn't mean unlimited materials.
The money side is straightforward but worth writing down exactly:
- Exam fee: $90, for both your initial attempt and any repeat attempt
- Master license application, licensing, renewal, or reinstatement: $198 for a two-year license term, under Plc 1002.13
These are separate transactions - passing the exam doesn't include the license fee, and the license fee doesn't include the exam fee. For the complete cost picture across both, see NH-ME Certification Cost 2026: Complete Pricing Breakdown.
On scheduling: state approval has to happen before you can book a test date. Once approved, your testing voucher is valid for 365 days, so there's real flexibility in when you sit - but that also means it's easy to let the clock run out if you don't plan deliberately. You must wait two days between attempts if you need to retake it, and if you need to cancel or reschedule an existing appointment, you're required to do so at least three days before the scheduled time. Full scheduling windows and deadline mechanics are covered in NH-ME Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Testing is available at a physical test center or remotely through Examroom.ai. If you go remote, you need a compatible computer - an iPad or tablet will not work for the remote proctoring setup.
Key Takeaway
Budget $90 per exam attempt separately from the $198 two-year license fee, and don't let your 365-day voucher expire without scheduling - start practicing well before you book a date.
The 12 Domains You're Actually Tested On
NH-ME isn't a generic electrical knowledge test - it's built from twelve defined content domains, each with its own fixed question count. Understanding the distribution tells you exactly where to spend your study hours.
| Domain | Question Count |
|---|---|
| 1. General Electrical Knowledge | 21 |
| 2. Equipment for General Use | 9 |
| 3. Motors and Generators | 19 |
| 4. Control Devices | 5 |
| 5. Special Conditions | 2 |
| 6. Special Equipment | 2 |
| 7. Special Occupancies | 3 |
| 8. Services and Service Equipment | 12 |
| 9. Branch Circuits and Conductors | 6 |
| 10. Feeders | 8 |
| 11. Wiring Methods & Materials | 14 |
| 12. Administrative | 25 |
Administrative is the single largest domain at 25 questions, edging out General Electrical Knowledge at 21 and Motors and Generators at 19. Together, those three domains make up nearly half of the total exam - meaning a candidate who only drills NEC-style code lookup questions while ignoring administrative rule content is leaving a large chunk of points unprepared for.
Administrative (25 questions)
This is the heaviest domain, and it's not primarily about wiring - it's about New Hampshire electrical law, licensing rules, and the regulatory framework you'll operate under as a master.
- Board authority, licensing rules, and administrative code provisions
- Permit and inspection processes specific to New Hampshire
- Professional responsibility and scope-of-license questions
General Electrical Knowledge (21 questions)
Foundational electrical theory and code application that underpins almost every other domain on the exam.
- Ohm's Law and basic circuit calculations
- Grounding and bonding fundamentals
- General NEC definitions and requirements
Motors and Generators (19 questions)
The second-heaviest technical domain, and one candidates frequently underestimate relative to its weight.
- Motor circuit conductor and overload sizing
- Disconnecting means requirements for motors
- Generator installation and overcurrent protection rules
The remaining domains - Wiring Methods & Materials (14), Services and Service Equipment (12), Feeders (8), Branch Circuits and Conductors (6), Equipment for General Use (9), Control Devices (5), Special Occupancies (3), and the two-question domains Special Conditions and Special Equipment - round out the remaining questions. Even the small domains can matter when you're a few points from the 70% line. A full domain-by-domain breakdown with what to expect in each is available in NH-ME Exam Domains 2026: Complete Guide to All 12 Content Areas, and if you want to gauge overall difficulty before you commit study time, How Hard Is the NH-ME Exam? Complete Difficulty Guide 2026 walks through what makes this exam challenging beyond raw content volume.
Eligibility: What You Need Before You Can Sit
NH-ME isn't open to just anyone with electrical experience. Standard eligibility requires:
- Passing the New Hampshire journeyman examination first
- Completing 2,000 hours of field experience as a journeyman before sitting for the master exam
- Receiving state approval before you're permitted to schedule a test date
That 2,000-hour requirement is a floor, not a suggestion - it has to be documented and accepted before Prov will let you book. If you're not sure how your current experience stacks up, the full breakdown of prerequisites is in NH-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify.
There's also an ongoing education obligation tied to license maintenance rather than exam eligibility: a 15-hour NEC-cycle update course, which must include at least one hour specifically covering New Hampshire law, rules, and installation concerns. This continuing education requirement runs on its own cycle and is separate from the two-year license renewal term - don't confuse the two when planning your compliance calendar.
The NEC Edition Question Nobody Talks About
This is a detail that trips up a surprising number of candidates. Prov publishes candidate bulletins periodically, and the referenced NEC edition can differ between bulletin versions. For example, one bulletin dated August 6, 2026 labels the master exam as tied to the 2020 NEC, while a separate bulletin dated June 24, 2026 labels the same exam as tied to the 2023 NEC. Both versions list the identical 126-question, 12-domain subject allocation - only the referenced code edition differs.
This is exactly the kind of detail that generic study advice glosses over. Our NH-ME Cheat Sheet 2026: One-Page Review of Must-Know Facts keeps a running note on which edition is currently active so you're not relying on outdated bulletin information.
What You Can Bring on Test Day
Since NH-ME is open-book, what you're allowed to bring - and how you mark it up - is tightly defined.
- Permitted references: American Electrician's Handbook, Ugly's Electrical References, and the specified New Hampshire laws and rules, in editions matched to your authorized exam
- Permitted markup: permanent tabs, highlighting, and pen underlining
- Prohibited: handwritten notes, movable tabs, and any inserted study material or loose pages
- Calculators: a simple four-function calculator is allowed at physical test centers; for remote Examroom.ai sessions, instructions require physical calculators to be removed from the testing area entirely
If you show up with a heavily annotated reference book full of sticky notes and pencil marginalia, expect it to be flagged or confiscated at check-in. Prep your books the way Prov actually allows, not the way you'd prep for an open-note college exam.
How to Approach Preparation by Domain Weight
Generic study techniques aren't the point here - the point is sequencing your prep around the actual point distribution. Since Administrative, General Electrical Knowledge, and Motors and Generators together account for roughly half the exam, they deserve proportionally more of your study calendar than the two-question domains like Special Conditions or Special Equipment.
Administrative + General Electrical Knowledge
- Review NH licensing rules, Board authority, and permit/inspection processes
- Refresh Ohm's Law, grounding/bonding, and general code definitions
Motors and Generators + Wiring Methods & Materials
- Work motor circuit sizing and disconnect scenarios
- Drill wiring method code lookups using your confirmed NEC edition
Services, Feeders, Branch Circuits, and the small domains
- Practice service and feeder calculations under time pressure
- Do a light final pass on Special Conditions, Special Equipment, Special Occupancies, and Control Devices

If you want to practice under conditions that mirror the real exam's 126-question, 5-hour format, timed practice sets on our practice test platform are built around this exact domain breakdown rather than generic electrical trivia.
Where NH-ME Fits in Your Career Path
Passing NH-ME converts a journeyman-level electrician into a master-eligible one - the credential that lets you pull your own permits and legally supervise work at the highest state-recognized level. It's not a certificate you add to a resume for flavor; it's a regulatory requirement tied directly to what work you're legally allowed to sign off on in New Hampshire. Understanding it clearly - the domains, the fee structure, the code-edition quirks, the eligibility hours - is the difference between walking into test day prepared and walking in guessing.
