Electrician exam FAQ
2337 answers about journeyman and master electrician exams: getting licensed, the exam itself, studying, the code book, calculations, exam day and what comes after, plus 2273 state-specific answers for all 50 states.
Getting licensed
What is the difference between a journeyman and a master electrician?
A journeyman is licensed to do electrical work under the general supervision of a master or contractor, and the exam tests the code a working electrician uses every day: branch circuits, feeders, grounding and bonding, wiring methods, box and conduit fill, motors and appliances. A master is licensed to plan, lay out and supervise work, usually to pull permits, and often to qualify a contracting business; the exam covers the same ground plus services, load calculations, transformers and the design and supervision articles. Titles and scopes vary by state, so the state pages on this site spell out the local version.
Who issues electrician licenses?
In most states a state board or department (often called the Electrical Board, Division of Occupational Licensing or Department of Labor and Industry) issues statewide licenses. A handful of states leave licensing to cities and counties, so a journeyman card from one city may not be recognised in the next. The state pages list who issues the license in each state.
How many hours of experience do I need before I can sit the exam?
Most states ask for about 8,000 hours (four years) of documented work under a licensed electrician for the journeyman exam, and another one to four years as a journeyman before the master exam. Many states let classroom hours from an apprenticeship or trade school replace part of the field time. Your state board's application lists exactly what counts and how it is verified.
Can I take the exam without an apprenticeship?
Usually yes, if you can document the required hours of supervised work by other means, typically with employer letters, pay records or a sworn affidavit. Some states will also accept a degree in electrical engineering or technology for part of the requirement. The board decides, and the application tells you what evidence it accepts.
How do I apply to take the exam?
You apply to the state licensing board first, with proof of experience and the application fee. Once the board approves you, it sends an eligibility letter or notifies the testing vendor, and only then can you schedule a seat. Buying study material does not start this process; the board does.
Who runs the actual test?
Most states contract a testing vendor to deliver the exam at computer-based testing centres. PSI, Prometric and Pearson VUE are the common ones, and a few states run their own sessions. The vendor publishes a candidate information bulletin for each state exam with the content outline, the allowed references and the rules for the day.
Does a license from one state work in another?
Sometimes. Many states have reciprocity agreements for journeyman licenses with neighbouring states, usually requiring that you passed a comparable exam and hold a license in good standing; master and contractor reciprocity is less common. If there is no agreement you generally apply and test in the new state, though your experience usually counts. The state pages note reciprocity where it exists.
How long does the whole process take?
From a complete application to an exam date is often four to eight weeks: the board reviews the application, approves you, and the vendor then offers seats based on availability at the centre you pick. Add your study time on top. If you are close to finishing your hours, apply as soon as you qualify and study while the paperwork moves.
How often can I retake the exam if I fail?
Most states allow a retake after a short waiting period, commonly 30 days, with a new exam fee each time. Some limit the number of attempts in a year or require extra training after repeated failures. Your score report tells you which sections were weak, which is where the next round of study should go.
Do I need a license to do electrical work on my own house?
Many states and cities allow a homeowner to do work on their own primary residence with a permit and an inspection, but the rules vary widely and some jurisdictions require a licensed electrician for anything beyond replacing like for like. This is a question for the local building department, not the licensing board.
The exam itself
Is the electrician exam open book?
Nearly every state exam is open book for the code portion: you bring the National Electrical Code and sometimes other approved references into the room. Open book does not mean easy. The clock is tight, and candidates who have not practised finding answers quickly run out of time. Treat the exam as a timed test of code navigation as much as of knowledge.
Which edition of the NEC does the exam use?
The edition named in your state's candidate bulletin, which is not always the newest one. States adopt new code cycles on their own schedules, and the exam is written to the edition the state has adopted. Bring the exact edition named; a newer book can have different article numbers and different answers.
How many questions are on the exam and how long do I get?
A typical journeyman exam has 80 to 100 questions in three to four hours; master exams tend to run longer and may be split into separately scored sections such as code knowledge and calculations. Some states add a business and law section for master or contractor candidates. The bulletin for your state gives the exact count and time.
What score do I need to pass?
Most states set the pass mark at 70 to 75 percent, and where the exam has separately scored sections you usually have to pass each section on its own. Your score report shows a pass or fail and a breakdown by content area rather than the exact questions you missed.
Is the exam multiple choice?
Yes. Almost all state electrician exams are four-option multiple choice delivered on a computer. There is no penalty for a wrong answer, so never leave a question blank: flag it, move on, and come back if time allows.
What topics come up most?
Across states the heaviest areas are general requirements and definitions (Articles 90 to 110), branch circuits and feeders (210 to 225), services (230), overcurrent protection (240), grounding and bonding (250), wiring methods and conductors (300 to 399), boxes (314), motors (430), and calculations drawn from Article 220 and Chapter 9. Master exams add more on services, transformers, load calculations and the design articles.
Are the questions in the study guide the real exam questions?
No. Licensing exam questions are confidential and are not published by any vendor. Practice questions are original material written to the same subjects, format and difficulty, with explanations that point to the code section. The value is in learning where answers live and how fast you can get there.
Is there a calculations section?
In most states calculations are mixed into the main exam, and in some, Texas for example, they are a separately scored portion you must pass on its own. Expect conductor ampacity with correction and adjustment factors, voltage drop, box and conduit fill, motor circuit sizing, dwelling and commercial load calculations, and transformer sizing.
Do master exams include business and law questions?
Some states fold a business and project management section into the master or contractor exam, covering estimating, contracts, lien law, payroll and OSHA basics; others test it as a separate exam. The candidate bulletin says which applies to you. If it is included, give it a week of its own, because it is easy points that most candidates skip.
Can I see my results right away?
At computer-based centres you usually get a preliminary pass or fail on screen or on a printout before you leave. The official result and the license itself come from the board afterwards, typically within a few weeks.
Studying
How long should I study?
Six to eight weeks at about ninety minutes a day works for most candidates who are already working in the trade. Split it three ways: learning the layout of the code book, working calculations until they are automatic, and sitting full-length timed practice exams in the last two weeks. Less than three weeks is rarely enough for the master exam.
What is the best way to use a study guide?
Work one article at a time, read the scope of the article in the code book, then answer the questions for that article and write down the code section for every question you miss. You are building a map of the book, not a list of answers. Save the full-length exams for the last two weeks and take them under exam conditions.
Should I memorise the code?
No. Memorise where things are, not what they say. The exam rewards candidates who can turn to the right table in seconds. Learn the chapter structure, the article numbers for the heavy topics and the location of the tables you use most, and let the book answer the question.
How do I know what to focus on?
The candidate bulletin for your state has a content outline with the percentage of questions in each area. Match your study hours to those percentages, then spend extra time on whatever your practice exams show you missing. Keep an error log by code section; the sections that keep appearing are your priority list.
Are flash cards worth it?
Yes, for the parts of the exam that reward recall: definitions, common ampacities, the trade sizes in Chapter 9, motor full-load currents and the thresholds in Article 210 and 250. Ten minutes of cards a day keeps those facts fresh so you do not spend exam time looking up things you should know cold.
Is an online practice kit better than a printed guide?
They do different jobs. Printed guides are where you learn the material and mark up your error log. The online kit gives you timed, randomised exams that feel like the real test and tell you instantly where you are weak. The Ultimate Combo includes both for that reason; if you can only have one and your exam is soon, the timed practice matters more.
What should I do the week before the exam?
Take one more full-length timed exam early in the week, then stop testing. Spend the last days re-reading your error log sections, rewriting your formula sheet from memory, and doing index drills. Sleep. Do not learn new material in the last 48 hours; it displaces what you already know.
I failed once. What should I change?
Read the score breakdown and go where the low numbers are. Most second attempts fail for the same reason as the first: time. Add timed drills to every session, cut the habit of reading every option before checking the code, and make sure your book has tabs you placed yourself. If calculations were the weak section, do them daily until the exam.
Can I study for the journeyman and master exams at the same time?
You can, but the study guides, calculations guides and flash cards are written separately for each level because the master exam adds services, load calculations, transformers and supervision. Pass the level you are applying for first; the master material builds on the journeyman material and is much easier once the first exam is behind you.
How do I study if English is not my first language?
Learn the code's vocabulary first: Article 100 definitions and the recurring phrases such as readily accessible, within sight and continuous load. Practice questions help you see how the exam phrases things. Some states offer the exam in Spanish or allow a translation dictionary; the candidate bulletin says what is permitted.
The code book
Which code book do I need?
The National Electrical Code (NFPA 70) in the edition your state tests on, usually the softbound version so it lies flat and can be tabbed. Check the bulletin for your state before you buy; a few states also allow or require other references such as the state's own electrical act or a calculations handbook.
Are tabs allowed in the exam room?
Most states allow permanent, commercially printed or self-adhesive tabs and highlighting, but not loose papers, sticky notes or handwritten notes beyond what the bulletin permits. The pre-printed tabs in our packages are made to meet the common rules. Read your state's bulletin for the exact wording before exam day.
How should I tab the code book?
Tab the chapters, the heavy articles (100, 110, 210, 215, 220, 230, 240, 250, 300, 310, 314, 404, 406, 430, 450) and the tables you use most: 310.16 and its correction and adjustment tables, Table 250.66, Table 250.122, the Chapter 9 fill tables and Annex C. Put the tabs in yourself even if they are pre-printed; placing them is your first pass through the book.
Can I write in my code book?
Usually yes, highlighting and short margin notes are permitted, but some states forbid handwritten notes entirely and will inspect the book. Where notes are allowed, keep them to formulas and cross-references near the tables you use. Check the bulletin for your state.
Can I use a code book with a different year?
Not in the exam. If the exam is written to one edition and you bring another, article numbers and table values can differ and you will lose time and points. Study from the edition you will test on, and keep the newer edition for the job once you are licensed.
What is the difference between the NEC and the NEC Handbook?
The Handbook contains the full code text plus commentary, diagrams and examples. It is excellent for studying but most states do not allow it in the exam room because of the commentary. Study with the Handbook if you like, but practise with the plain code book you will take to the test.
Do I need the state amendments?
Some states amend the NEC and test those amendments, often on the business or state law portion rather than the code portion. Your state page notes where amendments matter, and the state board publishes them. For most of the exam, the plain NEC is what you are tested on.
How do I get faster at finding things in the code?
Read the table of contents until you can place any topic in its chapter without looking. Then drill the index with a timer: pick 20 random terms a day, find the section, note the time. Under 30 seconds per lookup is the target. Speed comes from knowing the layout, not from turning pages faster.
Calculations
What calculations should I expect?
Conductor ampacity with temperature correction and adjustment for more than three current-carrying conductors; voltage drop, single and three phase; box fill (314.16) and conduit fill (Chapter 9 Tables 1, 4 and 5); motor full-load current, conductor, overload and short-circuit protection (Article 430); dwelling service and feeder loads by the standard and optional methods (Article 220); and transformer primary and secondary currents and protection (Article 450). Master exams add commercial and multi-family load calculations.
Can I bring a calculator?
Yes, a basic or scientific calculator that is non-programmable and silent is allowed in nearly every state; phones and anything with wireless or text storage are not. Bring two in case one fails, and practise on the same model you will use in the exam.
How do I calculate voltage drop?
For single phase use VD = 2 × K × I × L ÷ CM, and for three phase VD = 1.732 × K × I × L ÷ CM, where K is about 12.9 for copper and 21.2 for aluminium, I is the load current, L the one-way length in feet and CM the conductor area in circular mils from Chapter 9 Table 8. The code recommends keeping branch-circuit drop to 3 percent and total drop to 5 percent.
How do I size conductors for a continuous load?
Multiply the continuous load by 125 percent, add any non-continuous load, pick a conductor from Table 310.16 at the correct temperature column with at least that ampacity, then check that ampacity after temperature correction and adjustment still carries the actual load. The overcurrent device is sized from the same 125 percent figure.
What is the difference between the standard and optional dwelling calculation?
The standard method in Part III of Article 220 applies demand factors to each load category separately; the optional method in Part IV applies one demand factor to the total of most loads and is usually quicker and gives a smaller service. The exam asks for both, and the question tells you which to use; if it does not, read the setup for the word optional.
How do I size a transformer's overcurrent protection?
Find primary and secondary current from kVA and voltage (I = kVA × 1000 ÷ V for single phase, ÷ (V × 1.732) for three phase), then apply the percentages in Table 450.3(B) for 1000 volts or less: commonly 125 percent on the primary with no secondary protection, or 250 percent primary and 125 percent secondary. Round using the notes to the table and check the next standard size rule in 240.6.
Why do I keep getting motor questions wrong?
Because motor rules use table values, not nameplate values, for most sizing. Take full-load current from Tables 430.247 to 430.250 for conductors and short-circuit protection, use the nameplate only for overloads (430.32), and size the branch-circuit protection from Table 430.52 with the exceptions that allow the next standard size up. Work ten motor problems in a row and the pattern sticks.
Do I need to memorise formulas?
A short list, yes: Ohm's law and the power formulas, voltage drop, the single and three phase current formulas, and the 125 percent continuous load rule. Everything else comes from tables in the book. Write your formula sheet from memory at the start of every study session; you cannot bring it in, but you can bring the version in your head.
Exam day
What should I bring to the exam?
Government photo ID that matches your registration exactly, your eligibility or confirmation letter, the allowed code book and references in the edition named by the bulletin, two approved calculators and pencils if the centre asks for them. Leave phones, smart watches, bags and notes in the car or a locker.
Can I take breaks?
Most centres allow unscheduled breaks, but the clock keeps running and you cannot take anything out of or into the room. Use the restroom before you start and plan to sit through.
How should I pace myself?
Divide the time by the number of questions and keep a checkpoint every 20 questions. Answer what you know cold first, flag anything that needs a lookup, and come back in a second pass. A question that is taking more than three minutes is costing you two easier ones somewhere else.
What if I run out of time?
Make sure every question has an answer before the clock stops, since there is no penalty for guessing. In the last five minutes stop looking things up and fill in your best guess on everything still flagged.
What happens if I am late or miss my appointment?
Vendors generally treat a late arrival as a no-show, keep the fee and require you to reschedule and pay again. Arrive 30 minutes early, with the route and parking worked out the day before.
Can I reschedule?
Yes, usually online with the vendor up to a day or two before, sometimes with a fee inside the last 48 hours. The exact window is in your confirmation email.
After the exam
How do I get the license once I pass?
The board issues it after the vendor reports your pass, sometimes automatically and sometimes after you submit a final application and fee. Expect two to six weeks. You cannot work as a journeyman or master until the card or certificate number is issued.
How do I keep the license current?
Most states renew every one to three years and require continuing education, commonly four to sixteen hours per cycle with a code update course when a new edition is adopted. Missing a renewal usually means late fees and, after a grace period, retesting.
What can a master do that a journeyman cannot?
Depending on the state: pull permits, design and lay out installations, supervise journeymen and apprentices, and act as the qualifying party for an electrical contractor's license. Many states require a master license, or a master on staff, before a business can contract electrical work.
Do I need a contractor license as well?
If you plan to bid work under your own business name, most states require an electrical contractor license in addition to, or qualified by, a master license. Contractor licensing usually adds insurance, bonding and a business and law exam.
Does passing the exam make me eligible to work anywhere in the state?
Statewide licenses do, subject to local registration in some cities. In states where cities license separately, a pass with one city may not transfer to another. The state pages describe which model each state uses.
Packages and ordering
Which package should I buy?
If you already own the current code book with tabs, start with Study Guide + Flash Cards and add the calculations guide if arithmetic under time pressure worries you. If you own nothing yet, the Super Combo is the cheapest way to get the whole paper set, and the Ultimate Combo adds the online practice exams. Every package starts with the same state study guide, twelve practice exams and two full-length finals.
Are the materials state-specific?
The study guide, flash cards and online kit are built for your state and license level, following that state's content outline. The calculations guide and the code book are the same nationwide because the code is.
What if my state tests on an older NEC edition?
Check your candidate bulletin first. The packages on this site are built on the current edition; our fulfillment center also carries earlier editions, and the study guides are organised by article so they track across editions. Bring the code book edition your state names on exam day.
How are the packages delivered?
Printed study guides, calculations guides, flash cards and code books ship from our fulfillment center, 1 Exam Prep. Online test success kits and courses are delivered by email after purchase. Buy now opens secure checkout there; the price at checkout is the one that applies.
Does buying a package register me for the exam?
No. Applications, approval to test and scheduling are handled by your state licensing board and its testing vendor. A package gets you ready for the test itself.
Can I buy items individually?
Yes. The study guides, flash cards, calculations guide and online kits are sold on their own under Study guides, flash cards and online kits on the home page, for topping up a package you already own.
Is there a guarantee that I will pass?
No honest study material can promise that; passing depends on your preparation and the exam. What the packages do is cover the content outline for your state, give you timed practice that matches the real test, and show you exactly which code sections you still need to work on.
