Official-blueprint prep for the master electrician license in 9 states — Texas, Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming. Code-cited drills, real exam formats, and an AI tutor that explains every rule in plain English.
Master candidates don't get study blocks — they get gaps. Between jobs, at lunch, after hours in the truck. MasterElectricianPractice is built for those gaps, with progress that syncs across every device.
Turn downtime between calls into master-level NEC review that actually sticks.
Short, focused sessions designed for working journeymen with real schedules — and crews to run.
Stuck on service or feeder sizing? Ask the AI tutor for a plain-English walkthrough of any NEC rule, table, or calculation.
Analytics show accuracy per NEC chapter and per blueprint subject area, and exactly which articles still trip you up.
Field-tested study rhythms that fit between shifts, service calls, and running your own jobs.
Spaced repetition keeps service loads, transformer math, and motor calculations sharp until exam day.
Every state's official blueprint. One study system that mirrors how your state actually tests you.
Every simulation follows the subject blueprint your state board publishes — Texas splits the master exam into NEC Knowledge and Calculations, Colorado and the other states test a single master exam, and every question is weighted by the official per-subject quotas. No random draws.
See your accuracy by NEC chapter from Art. 90 through 840, plus per-question speed and a readiness score you can trust against your state's pass line.
Work your state's blueprint in order — services, feeders, branch circuits, wiring methods, equipment, then special occupancies — or jump straight to your weak spots.
Questions scale up as your code navigation and calculation speed improve, so every session pushes you a little further.
Every question explains the why and cites the exact NEC article or table, so you learn the code instead of memorizing answers.
The AI watches your simulations and serves the questions you need next — like a tutor who already graded your last attempt.
A straight path from journeyman to master — built on the blueprint your state actually uses.
Learn the subject areas of your state's master blueprint — Texas's ten NEC Knowledge areas and ten Calculations subjects, or the single-exam outlines Colorado, New Hampshire, Vermont, Maine, Delaware, Arkansas, Kentucky, and Wyoming publish — plus the index-first lookup habits every open-book exam rewards.
Practice service sizing, feeder and branch-circuit calcs, transformer protection, motor math, grounding, and renewable systems with your exam's NEC edition open — 2026 in Texas and Colorado, 2023 elsewhere — then review every explanation and its reference.
Take timed, full-length simulations in your state's real exam format and score yourself against its pass line until exam day feels routine.
MasterElectricianPractice prepares you for the master electrician license — the license to run your own jobs. In Texas the exam is scored in two open-book portions, NEC Knowledge and Calculations; most other states test a single master exam. Every program is built on its state board's official subject blueprint. The questions below sample the master-level topics that dominate those blueprints: service sizing, feeder calculations, transformer protection, motor calculations, grounding, and renewable energy. Select your answer below to see how the code reference works.
Branch-circuit conductors supplying a single continuous-duty motor with a nameplate full-load current of 20 A must have an ampacity of at least what value per NEC 430.22(A)?
The same open-book skills you will use at your state's test center, built into every drill and simulation.
MasterElectricianPractice pairs every practice question with instant, code-cited explanations, then builds your weak-area drills automatically — no more guessing what to study next.
Ask it anything — Article 90 to the Chapter 9 tables.
From journeymen chasing the upgrade to contractors running crews, MasterElectricianPractice fits how electricians in all nine states actually prepare.
You've held your license and logged your hours under a licensed master. Now sharpen the code navigation and calculation fluency the master exam demands.
Structured prep for your state's master exam — the two-part Texas format, Colorado's single master exam, or the ICC 701 route — with timed simulations and a readiness score against your state's pass line.
The master license is the one that lets you run your own jobs. Stay sharp and put your lead electricians on the same master-level prep.
Give students a practice environment that mirrors their state's real exam format and track class progress chapter by chapter.
Journeymen and master candidates across the nine states we cover — from Texas to Colorado to New Hampshire — preparing for their state board's master exam.
Master, Austin, TX
"The simulations laid out exactly like the real exam format. Once I stopped trying to memorize and learned to navigate the code, my practice scores crossed 70% and stayed there."
Master, Denver, CO
"Service and feeder calculations finally clicked. Every explanation pointed me back to the exact article or table, so I was practicing the code itself."
Master, San Antonio, TX
"The AI tutor walked me through transformer and motor math the way a good master would, and I passed the Calculations portion on my retake."
