Montana State Electrical Board • PSI Examination • 80 Questions • 240 Minutes • 75% Passing • Open Book • 2020 NEC
Ready to prepare for your Montana Master Electrician license? This complete study guide explains Montana's statewide electrical licensing process, the PSI Master Electrician examination, approved reference books, advanced load calculations, electrical theory, Montana amendments, and related study materials from Contractor Exam Preps.
Master electricians help design, plan, install, supervise, and maintain electrical systems that power homes, commercial buildings, industrial facilities, farms, and other properties.
They need a strong understanding of electrical safety, wiring methods, equipment, calculations, and the National Electrical Code.
They also need to know how electrical installations fit together.
A building may contain service equipment, feeders, distribution panels, motors, lighting, transformers, control equipment, and emergency power systems.
Every one of those systems has code requirements.
Every one can create trouble if something is installed incorrectly.
Electricity is extremely useful, but it is not known for giving second chances to careless wiring!
That is why advanced electrical knowledge matters.
For Montana electricians, becoming a Master Electrician can be an important step toward greater responsibility and the ability to serve as the qualified electrician for an unlimited electrical contracting business.
Montana has a statewide electrical licensing program.
The licensing authority is the Montana State Electrical Board, which operates through the Montana Department of Labor and Industry.
This is different from states where every city has its own separate Master Electrician examination.
In Montana, candidates apply to the State Electrical Board.
The Board evaluates their qualifications and decides whether they are eligible for examination.
Once approved, applicants receive an admission letter.
The approved candidate then contacts PSI to pay for and schedule the electrical examination.
The Board and PSI have different responsibilities.
The Board handles licensing eligibility and licensure.
PSI administers the test.
Understanding this process helps candidates avoid a common mistake: trying to schedule an examination before their license application has been approved.
The published Montana Master Electrician examination contains 80 questions.
Candidates receive 240 minutes, or four hours.
The minimum passing score is 75%.
For an 80-question examination, that means a candidate needs at least 60 correct answers.
The test is open book.
The Montana State Electrical Board currently identifies the 2020 National Electrical Code as the examination code edition.
This information is supported by the Board's current licensing pages and its published PSI candidate information bulletin.
The examination focuses on three broad subject areas.
These are the National Electrical Code, General Trade Knowledge and Theory, and Major Load Calculations.
The Board's published bulletin does not assign separate percentage weights to those three subjects.
Students should therefore avoid relying on invented topic percentages.
Instead, build a balanced study routine that covers all three areas.
Because the test allows 240 minutes for 80 questions, candidates have an average of three minutes per question.
That is enough time to work carefully, but only if the student understands the reference books and can solve calculations efficiently.
One complicated load calculation can use several minutes.
Several complicated calculations in a row can quickly make the clock feel much faster.
Montana's published PSI examination bulletin identifies the following references for its electrical examinations:
The bulletin also permits a silent, nonprinting, nonprogrammable calculator that is not designed for preprogrammed electrical calculations.
It explains that tabs and indexes may be used in the approved NEC.
It also allows personal highlighting, underlining, and notes in approved materials under its published rules.
However, candidates may not write, highlight, underline, or index the references during the examination.
Loose or attached additional papers are prohibited.
These rules differ from older Montana bulletins, so candidates should follow the latest instructions supplied for their actual appointment.
Do not assume that the rules for another state or another examination apply to Montana.
The National Electrical Code is updated regularly.
Different editions may contain different requirements, tables, definitions, and exceptions.
Montana's Board currently says its examinations are based on the 2020 NEC.
That is especially important because Contractor Exam Preps also sells newer electrical study materials based on the 2026 NEC.
A newer study guide can help students build general electrical knowledge.
It can provide calculation practice, codebook navigation exercises, and review of important electrical concepts.
However, newer code provisions may differ from the provisions used to score a 2020 NEC-based examination.
Candidates should learn the correct test edition before making code-based decisions.
For Montana's Master Electrician test, the 2020 NEC remains the official exam-cycle foundation unless the Board announces a change.
Master Electrician applicants must qualify through an approved experience or education pathway.
Montana's application checklist provides two principal routes for examination applicants.
The first is the experience route.
Under this route, an applicant must document 8,000 hours of legally obtained journeyman-level electrical experience.
The experience must involve electrical work in the wiring, installation, and repair of electrical apparatus and equipment for light, heat, and power.
The state requires third-party verification.
Under the published experience rule, no more than 50% of the qualifying experience may be residential work.
That means applicants should not assume all past electrical employment is automatically qualifying master-level experience.
The nature of the work and how it is documented matter.
The second pathway involves electrical engineering education.
An applicant who graduates as an electrical engineer from an accredited college or university may qualify with at least 2,000 hours of legally obtained practical electrical experience.
The Board reviews the applicant's education, experience, and documents.
An applicant who holds an active, unrestricted, and good-standing license from another state may also ask the Board to evaluate substantial equivalency under the applicable rules.
Substantial equivalency is not automatic reciprocity for every out-of-state license.
The Board must determine whether the other jurisdiction's qualifications meet Montana's requirements.
Montana's published Master Electrician application checklist lists a $190 application fee.
The Board's PSI candidate information bulletin lists an $85 Master Electrician examination fee.
Those are separate fees.
The application fee is paid as part of the licensing process.
The examination fee is paid when the approved applicant schedules testing with PSI.
The same PSI bulletin explains that examination fees are nonrefundable and nontransferable.
Candidates should check the current application and PSI instructions before paying because fees and policies can change.
The first major subject is the National Electrical Code.
NEC knowledge includes electrical installation requirements, conductor sizing, overcurrent protection, services, feeders, branch circuits, wiring methods, equipment, grounding, bonding, and special electrical conditions.
Students should understand where code requirements appear and how they work together.
For example, a conductor calculation may require using one NEC article to determine the load and another to determine the allowable conductor ampacity.
A service calculation may also require demand factors and equipment sizing rules.
The second official subject is General Trade Knowledge and Theory.
This involves electrical principles such as voltage, current, resistance, power, and common electrical relationships.
Electrical professionals should understand Ohm's law, basic AC theory, and safe electrical installation methods.
They also need to interpret drawings and recognize electrical equipment.
The third subject is Major Load Calculations.
Major load calculations are particularly important at the master level.
Candidates should practice service and feeder loads, demand factors, conductor sizing, motor calculations, transformer problems, and related applications.
They should know how to select the appropriate code tables.
They should also check the conditions and exceptions that affect a calculation.
Load calculations are not always difficult because the math is complicated.
Often the harder part is deciding which rules and numbers belong in the calculation.
For example, a building service calculation may require identifying lighting loads, receptacle loads, appliance loads, heating or cooling loads, and demand factors.
A motor calculation may require different sizing rules from an ordinary resistive load.
Transformer questions require an understanding of voltage, current, and power relationships.
Single-phase and three-phase calculations use different formulas.
Practice both.
Start with small problems that require one calculation.
Then work toward larger problems involving multiple tables and provisions.
Write down the known information.
Identify what the question asks.
Select the correct formula and NEC requirements.
Calculate carefully.
Finally, check whether the answer makes sense.
A calculation that produces a very unusual result deserves a second look before the answer is submitted.
Montana has state-specific electrical code amendments.
These amendments are important because the Board's PSI examination bulletin includes Montana Building Codes Amendments among the approved references.
They help explain how the adopted National Electrical Code applies within Montana.
For example, the published Montana amendment to NEC 210.12 addresses arc-fault circuit-interrupter protection and removes references to kitchens from the cited 2020 NEC provision.
That is exactly the type of state-specific difference candidates should recognize.
Do not assume that a general NEC rule has no state amendments.
Review the amendment language and learn where it fits within the code.
Montana also issues Electrical Contractor licenses through the State Electrical Board.
The contractor credential belongs to the business.
A Master Electrician license belongs to the individual.
For an unlimited Electrical Contractor license, Montana requires a licensed Master Electrician as the responsible electrician.
This responsibility allows the licensed contractor to perform work within the residential, commercial, industrial, and institutional scope authorized by the state.
The responsible Master Electrician must meet the applicable employment and responsibility requirements.
Montana's rules also recognize a limited Electrical Contractor license using a licensed Journeyman Electrician as the responsible electrician.
The limited contractor scope is narrower than an unlimited contractor's scope.
Businesses must also satisfy workers' compensation and unemployment insurance requirements, or qualify for the appropriate exemption.
Owning a Master Electrician license does not by itself create an Electrical Contractor business license.
Both sides of the licensing process must be handled correctly.
Montana's renewal cycle is biennial.
The Board identifies July 15 of even-numbered years as the renewal deadline for electricians and electrical contractors.
Active licensees generally need 16 hours of approved continuing education each renewal period.
At least eight hours must address NEC updates.
Continuing education is an important part of maintaining code knowledge after passing the examination.
Electrical requirements change over time.
Keeping up with those changes helps professionals remain informed about newer equipment and installation practices.

Applicants should still obtain Montana Building Codes Amendments and the appropriate *Printreading* reference separately when needed.
Begin by gathering the official instructions.
Study the 2020 NEC before moving to newer code topics.
Review the Montana amendments.
Practice electrical theory.
Work on major load calculations several times each week.
Include plan reading and equipment recognition.
Practice with an 80-question examination and a four-hour timer.

Preparing for the Montana Master Electrician examination is an important step for experienced electricians who want to advance their professional qualifications and take on greater responsibility.
Master electricians help plan, lay out, install, troubleshoot, and supervise electrical systems.
They work with electrical services, feeders, branch circuits, distribution equipment, motors, generators, transformers, wiring methods, and many other installations.
They also need to understand advanced electrical calculations, technical drawings, equipment requirements, and safe work practices.
These skills are important because electrical systems are closely connected.
A change in load can affect conductor sizing.
A different motor installation may require different protection.
An incorrect grounding or bonding connection can create serious hazards.
A complete understanding of electrical codes helps professionals make better decisions.
Montana Master Electrician licensing is administered statewide through the Montana State Electrical Board.
Applicants must first qualify for examination.
The Board reviews experience, education, and any required supporting documents.
Approved applicants receive an admission letter and then schedule their examination with PSI.
That order matters.
Students should not try to register for the examination before receiving Board approval.
The current published Montana Master Electrician examination contains 80 questions.
Candidates have four hours to complete it.
The passing score is 75%, meaning at least 60 of the 80 questions must be answered correctly.
The examination is open book.
Montana currently identifies the 2020 National Electrical Code as the examination code edition.
The approved references also include Montana Building Codes Amendments and *Printreading* by David L. Hittinger based on the 2020 NEC.
Candidates should review the current PSI rules before bringing any materials to the testing center.
Permitted tabs, notes, calculators, and other reference conditions are controlled by the examination provider.
Montana's published examination focuses on three broad subject areas.
The first is the National Electrical Code.
The second is General Trade Knowledge and Theory.
The third is Major Load Calculations.
The official bulletin does not publish percentage weights for these subjects.
That means candidates should prepare all three instead of relying on an unsupported question breakdown.
Major load calculations deserve regular practice.
Students should work with dwelling and commercial electrical loads, services, feeders, motors, transformers, demand factors, conductor sizing, and related NEC requirements.
They should also review Ohm's law, electrical power, voltage, current, resistance, and single-phase and three-phase calculations.
Codebook navigation is another important skill.
Being able to find the correct table or exception quickly can make a major difference during a timed open-book exam.
Because the test allows an average of three minutes per question, candidates should learn to work accurately without spending too long searching.
Contractor Exam Preps offers several related study materials.
The Montana 2026 Master Electrician Exam Prep and Study Guide includes 12 practice examinations and two full final examinations.
It can support repeated electrical review and exam-style preparation.
The Montana 2026 Master Electrician Study Guide and NEC Combo adds the 2026 NEC paperback with tabs for current-code learning.
For more extensive preparation, the Montana Master Electrician Super Combo combines the study guide, calculations guide, NEC, tabs, and flash cards.
These newer products help students review electrical concepts and develop good study habits.
However, the included 2026 NEC is not the official 2020 NEC reference listed for the current Montana examination.
Candidates should make that distinction before purchasing materials.
The store also offers a 2020 Master Electrician Jump Start Package.
It includes a 2020 NEC, master-level practice, calculation review, and online study resources.
This can be useful for candidates who want their general study materials to match the listed NEC examination cycle.
Even with that package, applicants must separately confirm the Montana amendments and approved printreading reference.
A six-week study schedule can make preparation more organized.
During the first week, review licensing requirements and become familiar with the 2020 NEC.
During the second week, study services, feeders, branch circuits, grounding, and bonding.
Use the third week for major load calculations.
During the fourth week, focus on wiring methods and electrical theory.
Use the fifth week for motors, transformers, print reading, and Montana amendments.
During the final week, complete several timed practice examinations using the four-hour limit.
Review missed questions and identify the controlling code provisions.
Remember that Montana's Master Electrician license is separate from an Electrical Contractor business license.
An unlimited Electrical Contractor must have a Montana-licensed Master Electrician serving as its responsible electrician.
The contracting business must also satisfy the appropriate state licensing and employment-related requirements.
Master electricians must maintain their professional qualifications after passing the examination.
Montana uses a biennial renewal cycle, with a July 15 deadline in even-numbered years.
Active electricians generally need 16 continuing education hours per renewal period, including at least eight hours involving NEC updates.
Continuing education helps electrical professionals stay informed as codes and equipment evolve.
The Montana Master Electrician examination is not just a test of memorization.
It rewards strong technical understanding, accurate calculations, careful code interpretation, and dependable problem-solving habits.
By using the official Board requirements, studying the correct NEC edition, reviewing Montana amendments, practicing major load calculations, and using appropriate Contractor Exam Preps resources, candidates can approach their examination with a stronger, better-organized preparation plan.
