Ready to earn your Massachusetts Journeyman Electrician license? This Massachusetts Journeyman Electrician Contractor Exam Prep guide explains the state's education and experience requirements, PSI examination structure, approved electrical references, code calculations, study strategies, and Massachusetts-focused products from Contractor Exam Preps.

Massachusetts issues statewide electrical licenses through the Board of State Examiners of Electricians, part of the Massachusetts Division of Occupational Licensure.

The standard Journeyman Electrician license is commonly identified as the Class B license.

It allows qualified electricians to perform electrical work within the scope established by Massachusetts law and Board regulations.

The Class B license is an important step for electricians who want to move beyond apprenticeship and prepare for greater responsibility in the electrical trade.

Massachusetts also licenses Master Electricians, Systems Contractors, and Systems Technicians.

These classifications have different qualification and examination requirements.

For the standard Journeyman Electrician pathway, applicants must complete 8,000 hours of qualifying electrical work over a period of at least four years.

The work must be performed under the supervision required by Massachusetts law, including supervision by an appropriately licensed Massachusetts Journeyman Electrician.

Candidates must also complete 600 hours of Board-approved electrical education.

Massachusetts currently requires a 15-hour Board-approved Code Update course as part of the application process.

Applicants should collect work records, school certificates, approved training documents, and the information required by the Board before applying.

The examination process is administered by PSI Services LLC.

The Massachusetts Journeyman Electrician examination has two separate parts.

Part I is the primary technical and electrical-code examination.

The current examination outline identifies 80 questions with a time limit of 180 minutes, or three hours.

Part II is the Applied examination.

It contains 30 questions with a time limit of 60 minutes.

Both parts require a minimum passing score of 70%.

That normally means at least 56 correct answers on Part I and 21 correct answers on Part II.

The examinations are scored independently, and candidates must pass both parts to complete the required testing.

The examinations are open book, subject to PSI and Board rules regarding approved references, permitted markings, tabs, and materials brought into the examination area.

However, an open-book exam is not an invitation to bring every electrical book you own.

Only approved references may be used, and a candidate must follow the specific rules for the examination part being taken.

Reference books may include the National Electrical Code, the Massachusetts Electrical Code amendments, applicable state electrical regulations, and NFPA 72 when listed for the examination.

The exact editions permitted by PSI must be verified before the test.

Massachusetts adopted an electrical code based on the 2026 National Electrical Code effective April 24, 2026.

The state-specific electrical code is found in 527 CMR 12.00.

This is an important distinction because electrical code adoption and licensing examination updates may follow different schedules.

Some currently available Massachusetts exam-preparation resources and PSI materials still identify the 2023 NEC and 2022 NFPA 72 as references from the previous examination cycle.

PSI examination questions may be updated after a newer code becomes enforceable.

Therefore, candidates testing during the 2026 transition should check the current candidate bulletin and the editions accepted for their exact testing date.

Do not assume that the state's newly adopted code automatically changes every examination reference immediately.

Contractor Exam Preps offers a 2026 Massachusetts Journeyman Electrician Study Guide and NEC Combo.

The package includes a Massachusetts-focused Journeyman Electrician study guide and a 2026 NEC paperback with tabs.

This is useful for studying current electrical code concepts, learning article locations, understanding electrical calculations, and practicing reference navigation.

For candidates who prefer structured online learning, Contractor Exam Preps offers the Massachusetts Journeyman Electrician Part 1 Online Exam Prep.

This course focuses on technical NEC subjects, exam-style review, and open-book code lookup practice.

The store also offers a Massachusetts Journeyman Electrician Part 1 Ultimate Exam Prep Rental with specified reference rentals and course access.

These are real products available through ContractorExamPreps.com.

Applicants should always compare the books included in a package against the current PSI approved-reference list before deciding which reference to take to the testing center.

Part I of the Journeyman Electrician examination covers 13 major subject categories.

The largest category is Wiring Methods and Devices, containing 18 questions.

Services accounts for another 11 questions.

General Knowledge includes eight questions, and Grounding and Bonding includes seven.

Overcurrent Protection, Alarm Systems, and Photovoltaic systems contain six questions each.

Special Occupancies and Equipment contains five questions.

Motors and Energy Storage Systems contain four questions each.

Low-Voltage Distribution and Lighting contain two questions each.

Transformers account for one question.

Part II focuses on six applied subject categories.

Troubleshooting and Testing is the largest category, with six questions.

Circuit Calculations, Electrical Schematics and Plans, Materials and Components, and Massachusetts Amendments contain five questions each.

Licensing Laws and Regulations accounts for four questions.

That means Part II is not simply a shorter version of Part I.

It tests your ability to apply electrical knowledge to diagrams, equipment, troubleshooting, and Massachusetts-specific requirements.

Both examinations require technical understanding and good time management.

Part I allows an average of about 2.25 minutes per question.

Part II allows an average of two minutes per question.

That time can disappear quickly when a question involves a detailed NEC lookup or several electrical calculations.

A strong study plan combines field knowledge, formulas, Massachusetts amendments, approved reference navigation, and timed practice examinations.

Understanding Ohm's law, conductor ampacity, grounding, bonding, services, feeders, overcurrent protection, motors, transformers, and safety requirements provides an important foundation.

Candidates should also study modern electrical topics, including photovoltaic systems and battery energy storage.

The current Part I outline specifically includes both subjects.

Massachusetts electricians may encounter these technologies in residential, commercial, and industrial installations.

Knowing how to apply the NEC and Massachusetts amendments is important for both examination preparation and safe electrical work.

This complete guide includes licensing steps, examination tables, official subject weights, study strategies, reference information, a distribution diagram, a six-week plan, Contractor Exam Preps products, a credential panel, interactive FAQs, a related 1ExamPrep video, and a conclusion.

Important Massachusetts Journeyman Electrician 2026 Update: Massachusetts administers a two-part, open-book Journeyman Electrician licensing examination through PSI. Current examination information lists 80 questions in 180 minutes for Part I and 30 questions in 60 minutes for Part II, with 70% required on each part. The standard licensing path requires 8,000 qualifying work hours over at least four years, 600 hours of Board-approved education, and a 15-hour code-update course. Massachusetts adopted its 2026 NEC-based Electrical Code effective April 24, 2026, but examination reference editions may change on a separate schedule. Some preparation materials still refer to the prior 2023 NEC and 2022 NFPA 72 exam cycle. Before testing, verify the active PSI bulletin, permitted reference editions, and Board reference-material policies.

What Is a Massachusetts Journeyman Electrician?

A Massachusetts Journeyman Electrician is a state-licensed electrical professional qualified to install, maintain, repair, and troubleshoot electrical systems within the authorized license scope.

The Journeyman Electrician license is commonly known as the Class B license.

It is administered by the Massachusetts Board of State Examiners of Electricians.

Journeyman electricians work with branch circuits, feeders, services, wiring methods, raceways, boxes, conductors, switches, receptacles, lighting equipment, motors, transformers, and other electrical components.

They are expected to understand applicable electrical codes and safe installation practices.

For example, installing a new electrical feeder involves more than selecting a wire that looks large enough.

Electricians must consider the load, conductor ampacity, overcurrent protection, grounding, bonding, equipment ratings, and the installation environment.

A feeder installed through a hot location or crowded raceway can require different conductor calculations than a feeder installed under ordinary conditions.

Proper grounding and bonding are also essential to electrical safety.

The Massachusetts Electrical Code includes the adopted National Electrical Code with state-specific amendments.

Electrical work must comply with the requirements in effect for the installation.

Journeyman Electricians can perform electrical work within their authorized scope, but the Class B license is not identical to a Class A Master Electrician license.

Master Electricians have additional qualifications and may carry different responsibilities involving electrical contracting, supervision, and business operations.

Massachusetts also has separate systems-related license classifications.

Candidates should confirm which credential matches their intended type of work.

Official license: Journeyman Electrician, Class B.

Board: Massachusetts Board of State Examiners of Electricians.

Standard education: 600 hours.

Standard experience: 8,000 hours over at least four years.

Code update: 15 hours.

How to Study for the Massachusetts Journeyman Electrician Exam

The most effective way to prepare for the Massachusetts Journeyman Electrician examination is to create separate study plans for Part I and Part II.

Part I is the larger technical examination, with 80 questions.

Part II focuses on applied electrical knowledge and Massachusetts rules, with 30 questions.

Start by reading the current PSI content outline and marking the subjects you understand well.

Then make a second list of subjects that require additional practice.

For Part I, prioritize Wiring Methods and Devices because that category contains 18 questions.

Review conductors, raceways, boxes, fittings, wiring methods, cables, and common installation requirements.

Next, study Services, which contains 11 questions.

Practice service calculations, disconnect requirements, service equipment rules, and conductor selection.

General Knowledge and Grounding and Bonding should also receive dedicated study time.

Review electrical theory, Ohm's law, power, voltage, current, resistance, branch circuits, feeders, grounding electrodes, and bonding requirements.

Practice the NEC rules rather than simply memorizing the locations of chapters.

Open-book examinations reward candidates who can understand a question and find the controlling rule efficiently.

When studying a code section, read the related exceptions and tables.

Then attempt a practice question without looking at the answer first.

Modern electrical systems are also important in Massachusetts.

The Part I outline includes six Photovoltaic questions and four Energy Storage Systems questions.

Review NEC requirements for solar equipment, circuits, disconnects, energy storage, and installation safety.

Part II requires practice with electrical calculations, schematic diagrams, equipment recognition, testing, troubleshooting, Massachusetts amendments, and licensing laws.

Because Part II allows one hour for 30 questions, practice recognizing the subject quickly.

The 2026 Massachusetts Journeyman Study Guide and NEC Combo supports current-code study and repeated reference navigation.

The Massachusetts Part I Online Exam Prep provides structured practice for the main electrical examination.

The Part I Ultimate Exam Prep Rental offers additional course access and listed reference-book rentals.

Always compare those references with the current PSI examination requirements, especially during the 2026 code transition.

Part I priority: Wiring Methods and Devices.

Next: Services, General Knowledge, Grounding and Bonding.

Modern systems: Solar and Energy Storage.

Part II priority: Troubleshooting, calculations, schematics, state amendments, and licensing laws.

Final practice: Two separate timed examination simulations.

How Hard Is the Massachusetts Journeyman Electrician Exam?

The Massachusetts Journeyman Electrician examination can be challenging because it tests electrical theory, installation requirements, modern electrical systems, and Massachusetts-specific rules.

Candidates must pass two separate PSI examination parts.

Part I includes 80 questions and covers a wide range of technical subjects.

Part II includes 30 applied questions involving calculations, diagrams, equipment, testing, troubleshooting, amendments, and licensing laws.

One common challenge is time management.

Part I provides 180 minutes, which works out to an average of 2.25 minutes per question.

Part II allows 60 minutes, or two minutes per question.

Open-book testing helps candidates verify code requirements, but it can also become a problem if they spend too long looking for information.

Students should learn the structure of their approved references before examination day.

Wiring Methods and Devices is especially important for Part I because it contains 18 questions.

Services adds another 11 questions.

Grounding and Bonding, Overcurrent Protection, Alarm Systems, Photovoltaic, and Energy Storage also deserve regular review.

Part II requires a different type of preparation.

Troubleshooting questions may ask candidates to identify a likely cause of an electrical problem or interpret test results.

Electrical schematics may involve symbols, connections, circuit paths, and equipment components.

Massachusetts amendments and licensing laws test state-specific knowledge that a generic NEC book may not fully explain.

This is why general electrical experience should be combined with Massachusetts-focused preparation.

The Massachusetts Journeyman Study Guide and NEC Combo helps organize electrical topics and reference navigation.

The Part I Online Exam Prep supports practice with common electrical code subjects and exam-style questions.

Remember that a study package cannot guarantee a passing score. Consistent practice and careful review of incorrect answers are the most useful study habits.

Ready for Massachusetts Journeyman Electrician Contractor Exam Prep?

Preparing for the Massachusetts Journeyman Electrician licensing examination starts with understanding the state's education, experience, code, and testing requirements.

Massachusetts issues the Class B Journeyman Electrician license through the Board of State Examiners of Electricians.

This credential is an important step for electrical professionals who have completed supervised training and want to advance in the electrical trade.

The standard licensing pathway requires 600 hours of Board-approved electrical education.

Applicants must also document 8,000 hours of qualifying electrical work completed over at least four years under the required supervision.

The current application process includes a 15-hour Board-approved Code Update course.

Before registering for examinations, candidates should gather their school records, work verification, and other required documents.

Applicants must receive approval through the Massachusetts licensing process before scheduling the PSI examinations.

The Massachusetts Journeyman Electrician test has two independent parts.

Part I contains 80 questions and has a time limit of 180 minutes.

Part II contains 30 questions and has a time limit of 60 minutes.

Both parts require a passing score of at least 70%.

This means candidates must normally answer at least 56 questions correctly on Part I and 21 questions correctly on Part II.

Passing only one part is not enough to complete the examination requirement.

The examinations are open book, but candidates must follow PSI and Board policies for approved reference materials.

Massachusetts adopted an electrical code based on the 2026 National Electrical Code effective April 24, 2026.

The state's electrical code is found in 527 CMR 12.00 and includes Massachusetts amendments to the NEC.

This matters because the code adopted for electrical installations and the edition approved for a particular PSI examination may not always change at exactly the same time.

Candidates should verify the NEC and NFPA 72 editions accepted for their actual testing date.

Existing exam preparation materials may still reference the 2023 NEC and 2022 NFPA 72 from the previous examination cycle.

Using the correct references is a major part of open-book preparation.

Part I includes thirteen subject categories.

Wiring Methods and Devices is the largest category, accounting for 18 questions.

Services contains 11 questions, followed by General Knowledge with eight questions and Grounding and Bonding with seven.

Other important topics include Overcurrent Protection, Alarm Systems, Photovoltaic, Special Occupancies and Equipment, Motors, Energy Storage Systems, Low-Voltage Distribution, Lighting, and Transformers.

These subjects require an understanding of electrical systems and the ability to apply code requirements to specific installation conditions.

Part II focuses on applied electrical knowledge.

The current outline includes Circuit Calculations, Electrical Schematics and Plans, Materials and Components, Troubleshooting and Testing, Massachusetts Amendments, and Licensing Laws and Regulations.

Troubleshooting and Testing is the largest Part II category, with six questions.

Because Part II allows only sixty minutes, candidates should practice recognizing questions quickly and applying the correct electrical principle or regulation.

Electrical mathematics should be part of every study plan.

Review Ohm's law, power, voltage, current, resistance, conductor sizing, electrical circuits, and related calculations.

Practice using a calculator accurately, but also understand which formula fits the problem.

Codebook navigation is equally important.

An open-book examination may allow approved references, but it does not provide unlimited time.

Students should learn how to locate NEC articles, definitions, tables, and exceptions efficiently.

Massachusetts candidates should also review the state electrical amendments and applicable licensing regulations.

For structured preparation, Contractor Exam Preps offers the 2026 Massachusetts Journeyman Electrician Study Guide and NEC Combo.

This package includes a Massachusetts-focused study guide and a tabbed 2026 NEC paperback.

The Massachusetts Journeyman Electrician Part I Online Exam Prep provides focused practice for the main technical examination.

The Part I Ultimate Exam Prep Rental includes reference rentals and course resources described on the store's product listing.

These products help candidates organize their studies, but they do not replace the official licensing requirements or guarantee a passing score.

A six-week preparation plan can help students review the examination topics in a manageable order.

Begin with electrical theory and NEC navigation.

Move through wiring methods, services, grounding, bonding, overcurrent protection, motors, and equipment.

Then review alarm systems, photovoltaic equipment, energy storage, special occupancies, and applied Part II subjects.

During the final week, complete separate timed practice examinations.

Use 180 minutes for an 80-question Part I simulation and 60 minutes for a 30-question Part II simulation.

Review missed questions carefully and identify the applicable electrical principle, code provision, or state regulation.

Passing both examinations is an important achievement, but successful applicants must still complete the Massachusetts licensing process.

They must also maintain their licenses through applicable renewal and continuing education requirements.

Electricians interested in owning or operating electrical contracting businesses should review the separate Class A Master Electrician pathway and related business obligations.

The larger goal is to become an electrical professional who understands how electrical systems work, applies safety requirements correctly, recognizes hazards, and performs authorized installations responsibly.

With accurate Massachusetts licensing information, focused NEC preparation, electrical calculation practice, approved references, and helpful study products from Contractor Exam Preps, candidates can prepare more effectively for both parts of the Journeyman Electrician examination.
