Free journeyman electrician practice test with explained answers
A journeyman electrician practice test helps only if it shows you why each answer is right and where to find the rule in your NEC. Work the three questions below with your book and a calculator, then read how to use a full timed test.
What a good practice test covers
State journeyman exams differ in length and passing score, but the bulletins we read share the same core: electrical theory and calculations, branch circuits, services and feeders, overcurrent protection, grounding and bonding, conductors, raceways and boxes, motors, lighting and equipment, special occupancies, and low-voltage systems and safety. The exam outline guide shows how much each area weighs. A good practice test follows those weights, mixes lookups with calculations, and runs on a clock.
3 sample questions
These are original questions written to the shared outline and the 2023 NEC. They are not real or recalled exam items.
1. Electrical theory. A resistive heater draws 12.5 amperes at 240 volts. What is its resistance?
- A. 9.6 ohms
- B. 19.2 ohms
- C. 30 ohms
- D. 3,000 ohms
Answer: B. Ohm's law: resistance equals voltage divided by current, so 240 ÷ 12.5 = 19.2 ohms. 9.6 ohms is what you get if you use 120 volts by mistake. 3,000 ohms multiplies voltage by current, which gives watts, not ohms. 30 ohms has no step behind it.
2. Three-phase power. A balanced three-phase load draws 30 amperes per phase on a 208-volt system. About how many kVA does it use?
- A. 6.2 kVA
- B. 10.8 kVA
- C. 18.7 kVA
- D. 3.6 kVA
Answer: B. Three-phase kVA equals volts times amperes times 1.732, divided by 1,000: 208 × 30 × 1.732 ÷ 1,000 = about 10.8 kVA. A leaves out the 1.732, which treats the load as single-phase. C multiplies by 3 instead of 1.732. D divides by 1.732 instead of multiplying.
3. Branch circuits. A branch circuit supplies only a continuous load of 16 amperes. Using the continuous-load rule for branch circuits in NEC Article 210 (2023), what is the smallest standard overcurrent device rating that works?
- A. 15 amperes
- B. 16 amperes
- C. 20 amperes
- D. 25 amperes
Answer: C. For a continuous load, the overcurrent device must be rated at least 125% of that load: 16 × 1.25 = 20 amperes, and 20 is a standard rating. A is smaller than the load itself. B covers the load but not the 125%. D works but is not the smallest. Find the rule in your own NEC: use the index under branch circuits and continuous loads, then confirm the standard ratings in Article 240.

Use the clock
Our full practice exam is 100 questions in 240 minutes, open book. That pace, about 2.4 minutes a question, is close to what the state bulletins we read allow. Answer the lookups you know fast, flag the long calculations and come back to them. If your state's exam is shorter or longer, scale the clock to match.

Reading your practice score
A practice score is not a prediction of your exam result. Use it to decide what to study next: compare each area's score with its weight, and work the heavy area where you lost the most. Then retake a fresh set on the clock. Our practice exam covers the areas states share and not your state's law and rules, so study those from your board. To turn your area scores into a weekly order, use our journeyman electrician study plan.

FAQ
Are these questions from the exam?
No. Every question is original and written to the subject areas the state bulletins share. Real and recalled exam items are never used.
Is there a free journeyman electrician practice test PDF?
Yes. Print our free journeyman electrician practice quiz (PDF): original questions with an answer key on page 2, and no email. Then take the free 10-question check to see your weakest area.
Which NEC edition do the questions use?
The 2023 NEC, the edition three of the four state bulletins we read test today. Check which edition your state names, and practice lookups in the book you will bring.
Does the practice test match my state's exam?
No practice test matches any one state's exam. Each state sets its own length, time, passing score and law questions. California, for example, allows 4.5 hours for its 100 questions (California exam guide), and Connecticut's journeyperson exam has no law questions (Connecticut guide). Ours covers the shared NEC and calculation areas. See the journeyman exam guide for how states differ.
