2026 NEC · Journeyman and Master
Electrician exam practice, timed like the real exam
This site is a timed practice simulator for the journeyman and master electrician licensing exams, built on the 2026 NEC. Start with the free ten-problem diagnostic, at real exam pace, and see every answer worked step by step when you finish.
- Timed at the pace of the real calculations portion.
- Every answer worked step by step, with the NEC section it comes from.
- No sign-up. New problems on every attempt.
How it works
Three steps, the same ones every time. The free tests need no account.
Take a timed test
Ten problems at real exam pace, with your own code book and calculator. The clock is the part of the exam most people never practice.
See where the points went
Your score against the 70% mark, the time you used and a breakdown by subject area, so you know what to study and what to leave alone.
Fix one subject at a time
Read the worked solution, find the section in your own book, then drill that subject with new numbers until it stops costing you points.
Made for the way the exam is given
Job experience does not prepare you for this exam. It asks for the minimum the Code permits, against a clock, with the book open. Practice has to do the same.
You know what is on the exam
Each practice page shows the official content outline: every subject area and how many scored questions it carries, taken from the PSI bulletin.
Timed like the exam
The same minutes per question as the real portion, a question navigator and mark-for-review, so the test center is not the first time you race the clock.
It tells you where it is in the code
Passing is mostly knowing how to move through the code book. Every solution names the article, section or table, so you find it in your own copy.
Answers are computed, not typed
A program solves each problem from its own numbers and writes the solution from the same steps. The answer key and the explanation cannot disagree.
A new version every attempt
The numbers change each time. You cannot memorize the answers, so the score you see is the score you have.
One low price, no bundle
The free tests need no account. Full access is one plan, month to month, with one-click cancelling and a 7-day refund of the first payment.
Every answer comes with its work
A score alone teaches nothing. When you finish a test you get the full solution of every problem, the mistake most people make on it and where to find it in the code.
A single-phase 120-volt circuit supplies a 70 A load through 3 AWG aluminum conductors. The one-way run is 75 feet. What is the approximate voltage drop?
- VD = 2 x K x I x L / CM.
- K = 21.2 for aluminum.
- 3 AWG has 52,620 circular mils (Chapter 9, Table 8).
- VD = 2 x 21.2 x 70 x 75 / 52,620 = 4.23 V, or 3.5% of 120 V.
- Use the ONE-WAY distance: the 2 factor already covers the return path.
Common mistake: doubling the one-way run, or using the factor for the wrong phase configuration.
Where it is in the code: NEC Chapter 9, Table 8 (circular mils); see 210.19(A) and 215.2(A) Informational Notes

Common questions
Is the practice test free?
Yes. The ten-problem diagnostic, the practice sets on each calculation page and all the guides are free and need no sign-up. The full simulator is a paid subscription.
Which code edition do the problems use?
The 2026 NEC. Texas references its electrician examinations to the 2026 NEC as of September 1, 2026.
Are these the real exam questions?
No. Every problem here is original. Nobody outside the exam provider has the real questions, and this site is not affiliated with any licensing board or exam provider.
What if I find a wrong answer?
Report it from the review of that problem. We check every report against the 2026 NEC, answer you, and list every fix on the corrections page.
