Apprentice to Master · 2020 & 2023 NEC
Electrician Exam Practice 2026 is an electrician exam prep app for iPhone and iPad. Every question you have to hunt for costs you two more you never reach, so it drills the navigation and calculations covered here against tables that have not moved in years.
Read a scenario, name the article, before you open anything. Article 310 or 240. Chapter 9 or the raceway article.
Derating, breaker sizing, conduit fill, box fill, voltage drop, grounding conductors, motor circuits, the full dwelling service calculation. Pure calculations, so they are generated rather than shipped as the same fifty questions reshuffled.
Every distractor is the number one specific mistake produces. Pick one and you learn which mistake you made.
Miss a calculation and you get numbered steps, so the skipped step is easy to find.
Code Basics, Conductors & Ampacity and Installation Rules, including the article navigation drills, the ampacity quizzes, and the working space, burial depth, support spacing and receptacle placement numbers you look up on site. All eight field calculators are free too.
Six rooms cover code-book navigation, conductors and ampacity, the installation rules, worked calculations, dwelling service and load calculations, and grounding with motors. Ten calculation shapes generate fresh problems. Special occupancies, hazardous locations and the low-voltage chapters are not covered yet.
Built on the 2023 NEC, and every table the app computes from is unchanged across the 2020 and 2023 cycles, so the arithmetic is the same arithmetic your paper asks for. What does move between editions is coverage: GFCI and AFCI scope, surge protection, equipment disconnects. Those are taught as rules to confirm in your own book rather than as numbers to memorise, and the app has a screen listing exactly which tables are stable and which areas are not.
Unlocks Worked Calculations, Service & Load Calc and Grounding & Motors, extra sets in every covered room, endless generated practice, the timed challenge, and Code Minute, one shared five-question challenge a day.
Yes. Electrician Exam Practice 2026 is an iPhone and iPad study app for apprentice, journeyman, master and contractor candidates working from 2023 NEC values. It drills code navigation and the calculations that fail people, and it names what it does not cover.
Many electrician exams let you bring the code book, but they are timed, so slow lookups cost you questions you never reach. The Code Basics room trains you to read a scenario and name the article, such as 310 or 240, before you open anything.
Ampacity derating, overcurrent sizing, conduit fill, box fill, voltage drop, equipment and electrode grounding conductors, motor circuits and the dwelling service calculation. Problems are generated, so you can practice without seeing the same question twice.
Yes. Eight field calculators are free: ampacity, conduit fill, box fill, voltage drop, grounding conductors, motor circuits, dwelling load and Ohm's law. They are study estimates with stated assumptions, not a substitute for the code book.
It is built on the 2023 NEC. Every table the app computes from is unchanged across the 2020 and 2023 cycles, and the app lists which areas, such as GFCI and AFCI scope, move between editions so you can confirm them in your own book.
No. It covers code-book navigation, conductors and ampacity, installation rules, worked calculations, dwelling service and load calculations, and grounding with motors. Special occupancies, hazardous locations and the low-voltage chapters are not covered yet.
The download is free and includes the Code Basics, Conductors and Ampacity, and Installation Rules rooms plus all eight calculators. There is no account, and your practice history stays on your device. Electrician+ is optional, and prices are shown in the app before you buy.
A study aid, not a code book. Not affiliated with, endorsed by, or connected to the NFPA. Concepts and calculations are written in original wording with article numbers cited so you can verify each one yourself. Requirements vary by the code edition your jurisdiction has adopted and by local amendments, so always check the code in force where you work.
