NH-ME Jobs

TL;DR
  • Master license eligibility requires a passed journeyman exam plus 2,000 hours of journeyman field experience.
  • The exam is 126 questions in 5 hours, open-book, with Administrative (25 questions) the largest domain.
  • Initial and repeat attempts each cost $90; the two-year license itself costs $198 to process under Plc 1002.13.
  • Employers value candidates who can pass domains like Motors and Generators (19 questions) and Wiring Methods & Materials, not just recite theory.

What the Master License Actually Unlocks

Holding a New Hampshire Master Electrician license does more than add a line to a resume - it's the credential that lets someone pull permits, supervise journeymen and apprentices, and legally take on the electrical contracting work that keeps commercial and residential projects moving in the state. Because the New Hampshire Electricians' Board (under the Office of Professional Licensure and Certification) restricts this authority to license holders, passing the NH-ME exam is the gatekeeping step between "experienced electrician" and "electrician who can run the job."

For anyone weighing whether the effort is worth it, it helps to look at this from a pure earnings and opportunity lens rather than just exam mechanics. Our Is the NH-ME Certification Worth It? Complete ROI Analysis 2026 breaks down that tradeoff, and the NH-ME Salary Guide 2026: Complete Earnings Analysis looks specifically at how the license changes earning potential over a career.

Why Employers Care: A master license signals that a candidate has already proven journeyman-level competency and logged 2,000 hours of field experience beyond it - employers don't have to guess whether someone can run a crew or sign off on permitted work.

Who Hires NH Master Electricians

The job titles built around this license tend to cluster into a few categories:

  • Electrical contracting firms that need a licensed master on staff to pull permits and legally bid larger commercial or industrial jobs.
  • Facilities and maintenance departments at hospitals, manufacturing plants, and institutional campuses that require in-house licensed supervision for code-compliant repairs and upgrades.
  • Design-build and general contracting companies that want a master electrician on the team to review plans against the New Hampshire laws and rules and the assigned NEC edition.
  • Solo contractors who use the master license to open their own shop, hire journeymen, and take on larger-scope service and feeder work independently.

In every one of these paths, the license is treated as proof of a specific skill set - not a formality. That's why the content of the exam itself matters so much to how job-ready a candidate looks.

Eligibility You Need Before You Can Even Sit for It

Before job titles like "master electrician" or "licensed supervisor" are even on the table, a candidate has to meet the standard eligibility path: pass the journeyman examination and complete 2,000 hours of field experience as a journeyman. State approval has to be granted before the exam can be scheduled, and once approved, the testing voucher is valid for 365 days.

If you're still mapping out whether you meet this bar, the full breakdown of prerequisites lives in NH-ME Requirements 2026: Eligibility, Prerequisites & How to Qualify. Getting this timeline wrong - scheduling before you've logged your hours, or letting a voucher lapse - is one of the most common ways candidates delay their job search unnecessarily.

Key Takeaway

Track your 2,000 hours of journeyman field experience carefully and get state approval locked in before you start shopping for exam dates - your voucher only lasts 365 days once issued.

Exam Domains That Map Directly to Job Duties

The NH-ME exam covers 126 questions across 12 domains, and the weighting isn't arbitrary - it reflects what a licensed master is actually expected to handle on a job site. The three heaviest domains are Administrative (25 questions), General Electrical Knowledge (21 questions), and Motors and Generators (19 questions). For a full walkthrough of every domain and how they're weighted, see NH-ME Exam Domains 2026: Complete Guide to All 12 Content Areas.

Domain 12: Administrative

This is the largest single domain on the exam, and it reflects the reality of running licensed work in New Hampshire - permits, code editions, and the state's own rules for licensees.

  • New Hampshire laws and rules governing licensed electrical work
  • Documentation and administrative responsibilities tied to permitted jobs

Domain 1: General Electrical Knowledge

Foundational code and theory questions that show up constantly in day-to-day troubleshooting and planning on real jobs.

  • Core NEC concepts and definitions
  • Fundamental electrical theory applied to field scenarios

Domain 3: Motors and Generators

With 19 questions, this domain is second only to General Electrical Knowledge in weight - a reflection of how often motor circuits and generator installations come up in commercial and industrial supervision work.

  • Motor branch-circuit and overload protection sizing
  • Generator installation and control requirements

Beyond these top three, the remaining domains - Equipment for General Use, Control Devices, Special Conditions, Special Equipment, Special Occupancies, Services and Service Equipment, Branch Circuits and Conductors, Feeders, and Wiring Methods & Materials - round out the full scope of what a licensed master is presumed to know once hired. Services and Service Equipment (14 questions) and Wiring Methods & Materials (25 combined with Administrative territory in weight terms among the higher counts) both carry real weight, since service work and wiring installation methods are core to almost every job a master electrician signs off on.

Code Edition Matters for the Job, Not Just the Test: Prov's bulletins have listed different NEC editions in different cycles - one bulletin ties the exam to NEC 2020, another to NEC 2023. Confirm the assigned edition with Prov before buying references or answering code-specific questions, since using the wrong edition on the job (not just the exam) creates real compliance risk.

Exam Format, Fees, and Scheduling Mechanics

The exam itself is computer-based, open-book, four-option multiple choice: 126 questions, 5 hours, with a passing score of 70%. It's administered through Prov, and candidates can test at a physical test center or remotely through Examroom.ai. Remote testing requires a compatible computer - not an iPad or tablet - so anyone planning to test from home needs to verify their setup ahead of time.

ItemDetail
Exam fee (initial or repeat attempt)$90
Master license application/renewal/reinstatement$198 for a two-year term (Plc 1002.13)
Question count / time limit126 questions / 5 hours
Passing score70%
Voucher validity365 days from approval
Wait time between attempts2 days minimum before rescheduling

Allowed references include the American Electrician's Handbook, Ugly's Electrical References, and the specified New Hampshire laws and rules - all with editions matched to whichever exam version is authorized. Permanent tabs, highlighting, and pen underlining are allowed inside those references; handwritten notes, movable tabs, and inserted study material are not. At a test center, a simple four-function calculator is permitted, but remote-testing instructions require physical calculators to be removed entirely.

If you need to reschedule, do it at least three days before your appointment, and know that you must wait two full days between attempts if you need to retake it.

A Domain-Based Prep Timeline

Because Administrative, General Electrical Knowledge, and Motors and Generators together account for 65 of the exam's 126 questions, it makes sense to front-load prep time on those three before spreading remaining weeks across the smaller domains. A simple domain-weighted schedule keeps prep proportional to what's actually tested - and to what shows up on the job afterward.

Weeks 1-2

Administrative & General Electrical Knowledge

  • Review New Hampshire laws and rules referenced in the exam
  • Work through core NEC definitions and theory fundamentals
Weeks 3-4

Motors and Generators, Services, Feeders

  • Practice motor and generator sizing calculations
  • Drill service equipment and feeder calculation questions
Weeks 5-6

Remaining Domains & Full Practice Exams

  • Cover Equipment for General Use, Control Devices, Wiring Methods & Materials, and the smaller domains
  • Run timed 126-question practice sets under open-book conditions

For a more detailed week-by-week breakdown of study strategy tied to each of the 12 domains, see NH-ME Study Guide 2026: How to Pass on Your First Attempt. And if you're still trying to gauge how much time to budget overall, How Hard Is the NH-ME Exam?

Key Takeaway

Spend the first two prep weeks on Administrative and General Electrical Knowledge - together they're 46 of 126 questions, the single biggest block on the exam.

Staying Employable After You're Licensed

Passing the exam and getting hired isn't the finish line. Master electricians in New Hampshire need to complete a 15-hour NEC-cycle update, including at least one hour covering New Hampshire law, rules, and installation concerns. This requirement is separate from the two-year license term itself, meaning renewal timing and continuing education timing don't automatically line up - something employers expect their licensed staff to track independently.

Employers evaluating a candidate's long-term value also look at whether someone treats the license as a floor rather than a ceiling. Running practice scenarios against real job conditions - sizing a feeder, verifying a motor circuit, checking a service upgrade against the current code edition - keeps the knowledge sharp between renewal cycles. Practicing with realistic, domain-weighted questions on our NH-ME practice test platform is one of the more direct ways to keep that knowledge fresh, whether you're prepping for the exam itself or refreshing before a renewal cycle.

If your goal is simply understanding the credential landscape before committing to an employer or a study plan, our foundational pieces - What Is NH-ME?, NH-ME Meaning, and NH-ME Certification - lay out the basics without assuming prior context.
