Box fill, grounding and bonding, Table 310.16, conduit fill, the dwelling load calc: in the Code book it's a wall of text. Here every topic fits on one page, with the drawing, the section number and what you need to remember. 77 illustrated pages.

These are real pages from the book. The table of contents is the full one: 10 parts and 72 topics.
You've read the wire size section three times. You close the book...
...and you can't remember why a bigger number means a smaller wire, or where AWG stops and kcmil starts. It was just lines of text.
Here wire sizes are one page, every conductor drawn side by side from 14 AWG up to 250 kcmil, each one with its area in circular mils from Chapter 9, Table 8.
And on the pages next to it every topic has its own: insulation letters, conductor colors, Table 310.16, ambient corrections and conduit fill.
First you understand why it works that way. Then the sizes stick on their own.
Electrical theory, reading the NEC, conductors, overcurrent protection, grounding and bonding, boxes and outlets, calculations, safety on the job, exam practice and a final review: 77 pages, all illustrated
Picture this:
Instead of rereading half a page on box fill without being able to see it...
...you open the page and find a box with every conductor counted: each wire counts 1, up to four grounds count 1 (each extra one adds 1/4), the device yoke counts 2 and pigtails count 0.
And Ohm's law, grounding and bonding, conduit fill, the dwelling load calculation and lockout/tagout turn into drawings and tables you can read at a glance.
You stop repeating and start understanding.
That's exactly what Electrician Exam Made Visual does. It's not “just another study guide.” It's 10 parts and 72 illustrated topics, and at the end 30 practice questions with explained answers and a final review of the numbers to know. Because what your brain sees in order, it remembers.
Because what your brain sees organized, it remembers.
Voltage, current and resistance, Ohm's law, the power wheel, series and parallel circuits, AC and DC, 120/240 V and three-phase, power factor, transformers and using your meters.
You stop flipping pages blind: what the NEC is, how the Code is arranged, how to read a section number, shall vs. permitted, the definitions you must know and where to look first.
You pick the wire and know why: AWG and kcmil, insulation letters, conductor colors, Table 310.16, the terminal temperature rule, ambient and bundling corrections, the small conductor rule, wiring methods and conduit fill.
Overload, short circuit and ground fault, standard sizes and the next size up, the 125% rule for continuous loads, GFCI and AFCI protection.
Grounding vs. bonding, the effective ground-fault path, the electrode system, ground rods, the main bonding jumper, sizing the GEC and the EGC, and bonding metal piping.
What counts in box fill and how to calculate it, boxes for fixtures and fans, receptacle spacing, the required branch circuits in a home and working space at panels.
Every calc in the same steps: Ohm's law and power problems, the dwelling load calculation with a worked service, voltage drop, motor circuits and three-phase.
Current and the human body, lockout/tagout, test before you touch, PPE and arc flash.
How the exam works and 30 original practice questions on theory, the NEC and calculations, with every answer explained.
The numbers to know, all on one page, for your last review before exam day.
At the end of the book: 30 practice questions with explained answers and a final review of the numbers to know.
How to tab and highlight your Code book for an open-book exam: which articles to tab, how to color-code them and how to find a section in seconds on exam day.
A full timed mock exam on theory, the NEC and calculations, with every answer explained, so you know why it is right and what to reread when you miss one.

For apprentices on the job, for anyone preparing for a journeyman electrician exam, and for electricians who already wire houses and want the Code to finally make sense. It starts at Ohm's law, but it goes on to Table 310.16 corrections, sizing the GEC and the EGC, voltage drop and a dwelling load calculation with a worked service. Check the table of contents above to see every topic.
It's built on the 2023 edition of NFPA 70, the National Electrical Code, plus NFPA 70E (2024 edition) for electrical safety and OSHA 29 CFR 1910.147 for lockout/tagout. Every rule comes with its section or table number, so you can check it in your own Code book. States adopt different editions (2020, 2023 or 2026), and some add local amendments. If your exam uses another edition, look up each section number in the Code book your exam allows: some numbers and rules changed between editions. Your testing provider's candidate bulletin tells you which edition applies.
No. It's an independent study book, not published by or affiliated with NFPA, any testing company or any state licensing board. It doesn't come with a certificate and doesn't count as classroom or continuing education hours. It doesn't reproduce the Code: it tells you which article to go to and how to read it.
No. It doesn't replace your apprenticeship, your classroom hours, your supervised work or your Code book. You study with it next to the Code, so on exam day you already know where to look. Most open-book exams only allow specific references: check your candidate bulletin before you take anything printed in.
No. The 30 questions in the book and the mock exam in the bonus are written for this book. They're not official questions from any exam: they're there to train you.
Yes. It's a high-resolution PDF: print the whole book or just the pages you want to keep in the truck.
30-day guarantee: tell us what didn't work and we'll refund 100%.
You don't have to reread the same page hoping this time it sticks.
You don't have to memorize Code rules you can't picture.
And you definitely don't have to walk into the exam not knowing where to start.
There's an easier way. And it's one click away. Now it's your turn.
