Kentucky's electrician and master electrician exams are open-book on the 2023 NEC. Everyone in the room has the same book. The people who pass are the ones who can find 250.66 in fifteen seconds and know which table to reach for without thinking. That is a trainable skill, and this bench trains it.
The Code Race gives you a rule and a clock and asks where it lives. Forty-five items, scored and timed, with a personal best to beat. Run it until your fingers know the book. There is a printable 51-item tab list to match.
The Calc Bench covers eight worked exercise types — dwelling and commercial service loads, 220.47 house loads, a 75 kVA transformer, voltage drop, box fill, conductor derating, motor sizing. The Circuit Generator then makes infinite fresh problems whose wrong answers model the classic mistakes, like forgetting the 2 in the voltage-drop formula.
Some things you simply have to carry in your head — which article covers what, whether a value is in Chapter 9 Table 4 or Table 5, what lives in Annex C versus Annex D. Those are drilled as their own category.
A receptacle outlet in a dwelling-unit bedroom fails and is replaced. What does the 2023 NEC require of the replacement?
Why: 406.4(D) carries replacement rules forward — where AFCI protection is required for the area, a replaced receptacle has to be protected too. Replacement questions are a favorite because they punish people who only studied new construction.
Every plan opens the whole electrical bench.

The 2023 NEC. When Kentucky adopts a new edition, affected questions get rewritten and anyone with active access gets the update at no extra charge.
Both. The bank covers the shared code ground plus the business, law, and supervision material weighted toward the master exam. Drill by category to match whichever you are sitting.
Then start with the Calc Bench exercises, which walk a full calculation step by step, and then hammer the Circuit Generator. It never runs out of problems and its wrong answers are the mistakes people actually make, so recognizing them becomes part of the skill.
Yes. Print our tab list, tab your own book, then run Code Race against it. Tabs you placed yourself are the ones you will remember under a clock.
