Thinking about advancing from Journeyman Electrician to Master Electrician in New Hampshire? This complete guide explains the licensing process, master-level experience requirements, Prov examination, approved reference books, electrical calculations, state laws, fees, continuing education, and exam preparation products from Contractor Exam Preps.
Becoming a Master Electrician is an important professional milestone.
Electricians at this level need more than a good understanding of electrical wiring.
They must know how electrical systems are planned, installed, protected, inspected, and managed.
They also need to understand the laws and rules that govern electrical work.
A Master Electrician may be responsible for planning a large electrical service, supervising installation work, reviewing code requirements, or directing the electrical activities of a licensed business.
That responsibility requires technical knowledge, practical experience, and careful decisions.
Electrical systems are not the place for creative guessing. A wire does not become safer just because everyone agrees it looks big enough!
New Hampshire regulates this work through a statewide licensing system.
Applicants for the Master Electrician license must meet the state's experience and examination requirements before receiving approval.
The New Hampshire Electricians' Board, operating through the Office of Professional Licensure and Certification, commonly known as OPLC, regulates electrician licensing.
The Board establishes qualifications and rules for apprentices, journeyman electricians, master electricians, and other electrical licensing categories.
It reviews applications and determines eligibility to take the licensing examinations.
After the state approves an applicant, the candidate schedules the required exam through Prov, Inc.
Prov is the published testing provider for New Hampshire electrician licensing examinations.
The New Hampshire Master Electrician examination measures advanced electrical trade knowledge, code interpretation, practical calculations, and administrative understanding.
The examination covers electrical theory, equipment, motors, generators, control devices, service equipment, feeders, branch circuits, wiring methods, special electrical systems, and New Hampshire licensing rules.
It is an open-book examination.
However, candidates may use only the references specifically approved for their exam.
Study guides, online courses, and flash cards help with preparation but are not automatically authorized examination materials.
The official Prov Master Electrician (2023) examination contains 125 questions.
The exam allows five hours, equal to 300 minutes.
The passing requirement is 70%.
For a 125-question exam, candidates must answer at least 88 questions correctly to reach or exceed that percentage.
The average time available is approximately two minutes and 24 seconds per question.
Some electrical theory questions may be solved quickly.
Other questions involving motors, load calculations, code tables, or state licensing rules may take longer.
Good preparation includes accurate reference-book navigation and steady pacing.
Do not confuse the 125-question Master Electrician examination with New Hampshire's 110-question Journeyman Electrician examination.
They are separate tests with different subject distributions.
Some retail exam preparation descriptions list 126 Master Electrician questions.
The official Prov Candidate Information Bulletin dated July 25, 2025 identifies 125 questions for the Master Electrician (2023) examination.
The official twelve-category content outline also totals 125 questions.
This guide follows that official figure.
Candidates should check the most recent Prov bulletin when scheduling because examination specifications may change.
Yes. All New Hampshire electrician examinations listed in the current Prov bulletin are open book.
The Master Electrician (2023) reference list includes:
Although some listed state amendment materials have older dates, students should not remove them from the reference list without consulting Prov.
Prov identifies which state documents may be brought as printed copies.
Only the current exam bulletin controls permitted references.
New Hampshire's current state building code adopts the 2023 National Electrical Code.
The 2026 state building-code changes retained the 2023 NEC while updating several other code families.
Meanwhile, electrical preparation products based on the 2026 NEC are available from Contractor Exam Preps.
The newer 2026 NEC materials can help students study updated electrical concepts and become familiar with newer code provisions.
However, the published New Hampshire Master Electrician (2023) examination lists the 2023 NEC.
Candidates should not assume a 2026 NEC codebook is acceptable in the exam room.
For test preparation, use the edition currently approved by Prov.
For actual electrical installations, follow New Hampshire's adopted electrical code and applicable amendments.
The Prov Master Electrician (2023) outline includes twelve examination categories:
These categories total 125 questions.
The Administrative category is the largest, representing 25 questions or 20% of the exam.
General Electrical Knowledge contributes 21 questions, and Motors and Generators contributes 19.
These three categories account for 65 questions, or 52% of the examination.
The large Administrative section is one reason master-level preparation must include New Hampshire licensing laws and professional responsibilities.
The Administrative category contains 25 questions.
That makes it the largest single section on the exam.
Students should review RSA 319-C and New Hampshire Electricians' Board rules.
Important subjects include licensing classifications, applications, examinations, supervision, renewal, professional conduct, electrical business registration, inspections, and disciplinary procedures.
Review the requirements for electricians performing work under different credentials.
Understand the responsibilities of a master electrician serving as the responsible licensed individual for a business entity.
Study the state electrical amendments and how they relate to adopted code requirements.
Ignoring administrative study is a common mistake because candidates often feel more comfortable with hands-on electrical topics.
On this exam, state rules matter just as much as knowing how to size a conductor.
General Electrical Knowledge contains 21 questions.
Review voltage, current, resistance, power, energy, electrical circuit behavior, and fundamental safety concepts.
Practice Ohm's law and related power equations.

Practice using the correct NEC motor tables.
Review generator installation and applicable Article 445 requirements.
Master-level candidates should be comfortable solving multi-step motor calculations.
Services and Service Equipment accounts for 12 questions.
Students should review electrical service conductors, service equipment, main disconnecting means, overcurrent protection, equipment ratings, and grounding and bonding.
Practice service-load calculations for different types of occupancies.
Understand the difference between service equipment, feeders, and branch-circuit equipment.
Study working-space requirements, service installation methods, and electrical distribution arrangements.
Feeders accounts for eight questions.
Branch Circuits and Conductors accounts for six questions.
Review conductor ampacity, load calculations, overcurrent protection, continuous loads, receptacles, lighting, and feeder requirements.
Practice conductor-sizing adjustments and corrections.
Learn how branch circuits and feeders fit into an electrical distribution system.
Understand that proper sizing depends on both the load and the applicable NEC installation rules.
Wiring Methods and Materials contains 14 questions.
Study electrical metallic tubing, rigid metal conduit, flexible raceways, nonmetallic wiring methods, cable assemblies, junction boxes, fittings, and supports.
Practice box fill and conduit fill calculations.
Review where different wiring methods are permitted or restricted.
Understand the effect of damp, wet, corrosive, and other installation environments.
Study conductor insulation, temperature ratings, and equipment termination requirements.
Grounding and bonding appears throughout multiple examination subjects.
It is not listed as a separate counted category in the official blueprint.
Study NEC Article 250 carefully.
Learn about grounding electrodes, equipment grounding conductors, bonding jumpers, and separately derived systems.
Understand why electrical grounding and bonding are different functions.

Special Conditions contains two questions.
Review the applicable subjects in NEC Chapters 5, 6, and 7.
Examples include hazardous locations, emergency systems, standby systems, electric vehicle charging, renewable energy equipment, and other special electrical installations.
Not every example will appear on the exam, but understanding the code organization helps candidates prepare.
Under Elec 304.01(f), a Master Electrician applicant must have passed the journeyman examination and obtained 2,000 hours of field experience as a journeyman performing qualifying electrical installations before taking the Master Electrician examination.
Those hours are in addition to the experience used to qualify at the journeyman level.
The standard journeyman pathway includes 8,000 hours of qualifying apprenticeship field experience and the applicable electrical education requirement.
Applicants therefore often accumulate at least 10,000 hours across the apprentice and journeyman stages of the standard pathway.
However, the Board evaluates exact experience qualifications, alternative pathways, endorsement, and documentation according to its rules.
Applicants should not assume all previous electrical work automatically counts toward the additional 2,000 hours.
The current New Hampshire OPLC fee schedule under Plc 1002.13 lists $198 for a Master Electrician license application and licensing, including initial issuance, renewal, or reinstatement after expiration, for a two-year license term.
The published Prov Master Electrician examination fee is $90.
These are separate licensing and testing charges.
Applicants should use the current OPLC payment instructions and avoid assuming older fee schedules remain correct.
New Hampshire Master Electricians must complete 15 hours of approved continuing education in connection with new National Electrical Code publication cycles.
The applicable rules include instruction on the NEC and at least one hour addressing New Hampshire electrical law, Board rules, and installation concerns.
This requirement is not simply a fixed number of hours at every biennial renewal.
Licensees should review the current Elec 403 requirements and OPLC continuing education information.
Approved training helps electricians stay current as electrical products and code requirements change.
Journeyman and Master Electrician are different license levels.
The journeyman examination contains 110 questions and allows 4.5 hours.
The master examination contains 125 questions and allows five hours.
The master examination places considerably more weight on Administrative rules.
The standard master qualification also requires an additional 2,000 hours of journeyman electrical installation experience after passing the journeyman examination.
Students preparing for the master examination should use master-level references and practice materials.
New Hampshire Master Electrician licensing is an individual professional credential.
Under state law, an electrical corporation or partnership may need its own electrical business license.
The applicable rules address the licensed master electrician directly responsible for the entity's electrical business affairs.
Operating as a sole proprietor or under a corporation or partnership can involve different legal responsibilities.
Check the business structure, electrical license status, supervision requirements, and any local permits before offering electrical contracting services.

Preparing for the New Hampshire Master Electrician examination is an important step for licensed electricians who want to advance their careers.
The Master Electrician credential represents a higher level of electrical responsibility.
Master electricians need a strong understanding of electrical theory, practical installation methods, electrical safety, and the National Electrical Code.
They also need to know the state laws that govern licensed electrical work.
New Hampshire regulates Master Electricians through the Electricians' Board within the Office of Professional Licensure and Certification.
The Board establishes licensing qualifications and determines whether candidates are eligible to take the examination.
Prov, Inc. administers the state electrician licensing tests after applicants receive the required approval.
The official Master Electrician (2023) examination contains 125 questions.
Candidates have five hours to complete the exam.
The passing requirement is 70%.
For 125 equally scored questions, at least 88 answers must be correct.
The examination is open book, but candidates must use only the references permitted by Prov.
The approved Master Electrician (2023) reference list includes the 2023 National Electrical Code, the American Electrician's Handbook, Ugly's Electrical References, New Hampshire electrical laws and rules, and specified state amendment documents.
Knowing how to navigate these references is an important part of preparation.
Students should practice identifying the correct NEC article, finding the appropriate table, and checking all applicable conditions.
They should also become familiar with the state's electrical licensing regulations.
Administrative questions are especially important on the New Hampshire Master Electrician examination.
The official blueprint includes 25 Administrative questions, more than any other individual category.
That is 20% of the examination.
These questions concern New Hampshire electrical laws, Board rules, license classifications, supervision, business requirements, and other professional responsibilities.
Candidates who focus only on electrical wiring and calculations may overlook a large portion of the exam.
General Electrical Knowledge is the second-largest category, containing 21 questions.
Students need to understand voltage, current, resistance, power, electrical circuits, and technical calculations.
Motors and Generators is the third-largest category with 19 questions.
Motor study should include current calculations, motor conductors, overload protection, short-circuit protection, controllers, and motor disconnecting means.
Wiring Methods and Materials adds 14 questions.
This includes conduit, cable systems, raceways, boxes, fittings, and installation methods.
Students should practice box fill, conduit fill, and conductor sizing.
Services and Service Equipment contributes 12 questions.
Important subjects include electrical services, service disconnects, overcurrent protection, grounding, bonding, and service-load calculations.
Feeders contains eight questions, while Branch Circuits and Conductors contains six.
Both subjects require understanding loads, conductor ampacity, protective devices, and the relationship between parts of an electrical distribution system.
Other subjects include Equipment for General Use, Control Devices, Special Conditions, Special Equipment, and Special Occupancies.
These categories may have fewer questions, but they still matter when candidates are working toward a passing score.
Grounding and bonding are important across several of these areas.
Electrical professionals need to understand how grounding electrode systems, equipment grounding conductors, and bonding connections contribute to electrical safety.
Accurate electrical calculations also deserve steady practice.
Students should review single-phase and three-phase formulas, motor calculations, conductor ampacity, service loads, feeders, box fill, and raceway fill.
Understanding why a calculation is performed is more useful than memorizing a number without context.
One important 2026 consideration is the National Electrical Code edition.
New Hampshire currently adopts the 2023 NEC.
The official Master Electrician (2023) examination also lists the 2023 NEC as its primary code reference.
Meanwhile, many newer study products use the 2026 NEC.
These newer materials can help electricians learn updated code topics and develop long-term electrical knowledge.
However, a newer study edition is not automatically an approved examination reference.
Students must confirm their test-day books using the current Prov Candidate Information Bulletin.
New Hampshire also requires practical experience before an electrician may qualify for the master examination.
Under Elec 304.01(f), applicants must have passed the journeyman examination and completed 2,000 hours of qualifying electrical installation field experience as a journeyman.
This is beyond the standard experience used to become a journeyman electrician.
Applicants should keep accurate employment records and submit the required state application documentation.
The current OPLC license fee schedule lists $198 for Master Electrician application and licensing over a two-year term.
The published Prov examination fee is $90.
These fees are separate, and candidates should confirm current payment instructions.
Licensed Master Electricians must also maintain continuing education requirements.
New Hampshire requires 15 hours of approved instruction related to new NEC code cycles, including state law and rule content.
Master Electricians planning to operate or supervise electrical businesses must understand the state's electrical entity licensing requirements.
A corporation or partnership may need a separate license and a properly licensed responsible electrician.
Contractor Exam Preps offers several products to support preparation.
The 2026 New Hampshire Master Electrician Super Combo includes a state-focused master study guide, electrician calculations guide, NEC paperback with tabs, and flash cards.
The New Hampshire Master Electrician and Calculations NEC Combo provides focused preparation in electrical theory, code navigation, and mathematics.
A separate New Hampshire practice exam guide offers twelve practice examinations and two final exams.
For students wanting materials based on the 2023 NEC, the store also offers general 2023 Master Electrician preparation packages and an online test success kit.
These general resources should be combined with New Hampshire-specific Administrative study.
A six-week preparation plan can make the material more manageable.
Begin with state licensing law, Board rules, and master-level qualifications.
Continue with electrical theory, calculations, motors, and generators.
Then study services, feeders, branch circuits, grounding, bonding, wiring methods, and equipment.
Finish with special electrical subjects and repeated practice examinations.
Use five-hour timed sessions to prepare for the actual 125-question examination.
Review mistakes carefully and repeat weak subjects until the underlying concepts make sense.
Good preparation combines real electrical experience with organized study and accurate code references.
With consistent effort and a careful understanding of state requirements, electricians can approach the New Hampshire Master Electrician examination with stronger knowledge and confidence.
New Hampshire Master Electrician Contractor Exam Prep helps licensed electrical professionals understand the state's master-level licensing requirements and prepare for the official examination.
