Free, and honest about one thing

NC Electrician Practice Questions: Free, by Topic

Fifty four topic sets of 25 questions each, a timed practice test, four labs, six games and a daily question, free and none of them asking for an account. The one exception is the calculation ladder, where rung one is free and the other seven come with the $79 purchase. They are written to the 2026 code numbering and North Carolina tests on the 2020 book, so this page names the sixteen sets where that matters.

Start here

Start the free practice test. Thirty timed questions, no account and no email address, with the arithmetic worked out on every miss and the code section named.

Free question sets by topic. Fifty four topics, 25 questions each, worked the same way. Use these once the practice test has told you which areas are weak.

The four hands-on labs. Bend conduit, wire a three way, fill a box and build a grounding electrode system, in the browser.

Every calculator, game and lab. The tools hub, with one line on what each one does.

The daily question. One question every morning with the working and the section, and a streak counter. Five minutes on the days the study hour does not happen.

The honest problem: they carry the 2026 numbering

North Carolina examinations require the National Electrical Code, 2020 edition, and the state enforces the 2020 North Carolina Electrical Code. Our question bank was written for a state that moved to the 2026 book.

The rules and the arithmetic are unaffected by that. The section numbers are not.

Our record of the moves runs from the 2023 edition to the 2026 edition. It does not reach back to 2020, and we have not built a 2020 crosswalk. So the list below tells you which sets cite a number that changed in the recent editions, which is where to be careful. It is not a translation table for your book.

The habit that solves it: when a worked answer gives you a section number, find the rule by subject in your own 2020 book and note the number it carries there.

The sixteen sets where the numbering matters

We checked all 54 sets. Sixteen of them cite a section that changed address between the 2023 and 2026 editions.

Load calculations, Article 220 in the older books and Article 120 in 2026

Ten sets cite the new article. Read Article 120 as the load calculation article, and find the rule by subject in Article 220 of your own book.

Transformer overcurrent protection, 450.3 in the 2023 edition and 450.5 in 2026

Protection against physical damage, 300.4 in the 2023 edition and 300.6 in 2026

The bar on re-bonding neutral to ground, 250.24(A)(5) in the 2023 edition and 250.24(B) in 2026

Systems over 1000 volts, Article 235 in the 2023 edition and Articles 265 through 268 with grounding at 270 in 2026

The other thirty eight sets read straight

The rest cite articles and sections that carry the same numbers in both editions we hold: Article 250 for grounding and bonding, Article 310 with the ampacity table at 310.16, Article 240 for overcurrent, 314.16 for box fill, Article 430 for motors, and the Chapter 9 tables.

We have not set the 2026 values against a 2020 printing row by row, so check any number that decides an answer in the book you are carrying. That is the right habit on an open book paper anyway.

Sets worth working first for a North Carolina candidate, given what the Board's reference list carries: grounding and bonding, grounding electrodes, box fill, conduit fill, motor calculations, small conductors and overcurrent, receptacle spacing and pools and spas.

The $79 question bank

The practice test ships 30 questions free. The full bank is 500, and the other 470 carry what the free ones carry: the arithmetic worked out, and a line on each wrong option naming the error that produces it.

$79 once for the other 148, if you want them. One payment, no subscription, no account, no password and no email address on file with us. The buy button sits on the practice test page.

The same payment opens the seven remaining rungs of the calculation ladder. Rung one is free and works with no network.

For context on the price: the Board's application and examination fee is $125 and is not refundable, so a second attempt costs more than the bank does.

Buying for a crew, a shop or a class? One payment covers everybody. Each person claims a seat with their own email on any device, and the seat licenses sit under the buy button on the practice test page.

What these questions are not

Every question is original. None of them came from a candidate's memory of a real paper, and none of them is real exam content.

We are not a training provider, an approved course or an examination vendor, and nothing on this site is endorsed by the North Carolina State Board of Examiners of Electrical Contractors or by PSI. We are independent of both.

Nothing here promises a pass. What it does is show you which questions you get wrong and why, which is the part you can act on.

Questions people ask

Are the practice questions free?

Fifty four topic sets of 25 questions each are free, and so are the first 30 questions of the timed practice test. The remaining 148 bank questions are $79 once.

Which NEC edition are the questions written on?

The 2026 numbering. North Carolina examinations require the 2020 edition, so this page names the sixteen sets that cite a section which changed address in the recent editions.

Do I need an account?

No. The free questions need no account, no email address and no payment, and they run in your browser.

Are these real North Carolina exam questions?

No. Every question is original and written by us. We do not publish real exam content or vendor material.

What does the $79 bank include?

The other 148 questions on the practice test page and the seven remaining rungs of the calculation ladder, in one payment with no subscription and no account.

Can I buy for a crew?

Yes. One payment covers everybody, and each person claims a seat with their own email on any device. The seat licenses sit under the buy button on the practice test page.

Will there be a 2020 numbered bank?

That is work we have not done, and we would rather say so than sell you a translation as though it were a product. The habit that works today is finding each rule by subject in your own 2020 book.
