How to Pass the Journeyman Electrician Exam: A Code Panel Member's Approach

Why Most Exam Prep Doesn’t Work

If you’re chasing a journeyman or master electrician licence, you’ve almost certainly been bombarded with ads. A 150-page guide that promises to get you through. A YouTube-only course. A boxed set of books and DVDs. According to Paul Abernathy, who has spent nearly 40 years teaching the National Electrical Code and sits on NEC Code-Making Panels 5 and 17, most of that material shares the same flaw: it doesn’t actually teach you the code.

“You’re not going to be successful, or at least you’re not going to retain any of it, if you use these other methods. If you just buy these little pamphlets that people are selling, like a 150-page guide, you don’t interact with anybody. You can’t ask questions.”

His argument is worth taking seriously. He’s not just an instructor. He helps write the book you’ll carry into the exam room. And his central message is that passing the exam and learning the NEC are the same job, not two different ones.

Learn the Code, Not Just the Exam

There’s a temptation to treat exam prep as a separate skill from being an electrician. Memorise a few hundred likely questions, learn some tricks for the multiple-choice format, and hope the real test looks like the practice test.

Abernathy rejects that approach outright. His programme is built around 19 units that take you through the National Electrical Code as a body of knowledge:

“Not just what you need to pass an exam, but literally teaches you the National Electrical Code.”

The reasoning is simple. Exam questions are written by people who know the code deeply, and they draw from the whole book. If your preparation only covers the topics a pamphlet author guessed would appear, you’re gambling. If you genuinely understand how the NEC is organised, every question becomes a navigation problem you already know how to solve.

Follow a Structured Path Through the NEC

One of the most useful takeaways from the walkthrough is the order in which the material is taught. It’s not random, and it mirrors how the codebook itself builds from foundations to applications:

1. Definitions: Article 100 comes first, because you cannot apply a rule if you don’t know what “continuous load”, “readily accessible”, or “feeder” actually mean in code language.
2. General provisions: The wiring and protection rules in Chapters 1 through 4 that apply to almost every installation.
3. Special provisions: The chapters that modify or supplement the general rules for particular situations.
4. Calculations: Load calculations for one-family, two-family, and multi-family dwellings under Article 220.
5. Non-dwelling load calculations: Commercial and industrial occupancies, where demand factors and different rules apply.
6. Special occupancies: Hazardous locations, healthcare facilities, and similar areas from Chapter 5.

Compare that with how most people study: open the book at whatever section they last struggled with on the job, skim it, and close it again. That’s not a study plan. It’s a habit that produces electricians who know a few articles very well and the rest hardly at all.

Read It to Comprehend It

Video-based training is everywhere now, and it’s tempting to think you can watch your way to a licence. Abernathy is a firm believer that video has a place, but only a supporting one:

“I’m a big believer that you have to read it to comprehend it. The videos are supplemental to that. They help foster an acknowledgement to what you’re studying.”

That matches what most successful test-takers report. Watching someone explain Table 310.16 is not the same as opening your own codebook, finding the table, and reading the ampacity of a 75°C copper conductor for yourself. The exam is open book in most states, and the skill it rewards is being able to locate and interpret text under time pressure. You only build that skill by reading.

A practical habit from the walkthrough: whenever the course material flags a section with chevrons, you stop and look it up in the NEC. Every reference becomes a reason to touch the codebook. Do that enough times and your hands learn where things live.

Practise With Advanced Questions

Structured reading gives you the map. Practice questions teach you to use it at speed. The programme described includes over 800 database questions plus competency review exams with answer keys, close to a thousand questions in total. The important detail isn’t the count. It’s the difficulty:

“They will make you think and prepare you for any electrical exam.”

Easy questions feel productive but don’t prepare you for anything. A good practice question forces you to read carefully, identify which article applies, find the right table or section, and sometimes combine two rules to reach an answer. That’s what the real exam does.

A worked example from the walkthrough is the classic 125% versus 80% confusion. Section 210.19(A) and 210.20(A) require branch-circuit conductors and overcurrent devices to be sized at 125% of the continuous load, while many electricians think of the same rule as “don’t load a breaker past 80%”. Both describe the same relationship from opposite directions, but candidates who haven’t worked through it in practice questions regularly pick the wrong multiplier on exam day.

Ask When You Don’t Understand

The final piece of Abernathy’s approach is the one most self-study materials lack entirely: a way to ask questions. His programme includes a built-in discussion feature where students post questions and he answers them directly, with worked explanations of the kind of 125% versus 80% problem above.

“If you run into something you don’t understand, guess what? You get to ask me right inside the program.”

Even if you’re not using his programme, the lesson holds. Find someone you can ask. A journeyman on your crew, an instructor at your apprenticeship, an online community of electricians. The alternative is carrying a misunderstanding all the way into the exam, where it will cost you marks on every question that touches it.

The Bottom Line

Strip away the sales pitch and the advice from a 40-year code veteran comes down to four things:

1. Study the NEC in a structured order, from definitions through general rules to calculations and special occupancies
2. Read the codebook yourself and treat videos as a supplement, not a substitute
3. Work through hundreds of exam-style questions that are hard enough to make you think
4. Get your questions answered rather than guessing and hoping

None of that is a shortcut. That’s exactly the point. As Abernathy puts it, the right way to do it is to be structured, and the electricians who pass are the ones who learn the code rather than trying to outsmart the exam.

How NEC Mastery Fits Into This

Abernathy’s method depends on two things being available to you: a structured path through the code and a deep well of demanding practice questions. NEC Mastery is built around the second and supports the first.

• 8,000+ exam-style questions give you far more than a thousand questions to work through, organised by NEC article so you can drill definitions, then general provisions, then Article 220 calculations in the same structured order he recommends
• Detailed explanations referencing specific NEC sections do the job of the built-in Q&A for the most common sticking points, showing exactly where 210.19, 220.42, or 310.16 answers the question so you read the code rather than just memorise a letter
• Timed mock exams weighted to your exam type replicate the pressure of the real journeyman or master test and tell you whether you can find answers in the codebook fast enough
• No pamphlet, no DVDs: it pairs directly with your own copy of the NEC, because the codebook is the one study resource you’ll actually carry into the exam room
