About this site

Why it starts with the calculations
In fiscal 2025, only about 1 in 5 candidates passed the journeyman or master calculations part. A fixed question bank is not enough for that part: you need to practice the method on different numbers and find the right table in the book fast. So every problem here is generated with new numbers and every step names the NEC section.
Where the facts come from
- Exam format: the PSI candidate bulletin (updated 9/15/2026) and the TDLR exam page.
- NEC edition: TDLR adopted the 2026 NEC in 16 TAC §73.100, effective Sep 1, 2026 (TDLR notice).
- Licenses, fees and hours: TDLR's apply and renew pages, linked from each guide.
- Pass rates: TDLR's yearly exam statistics.
Texas facts were last checked on Nov 9, 2026. Every guide shows its own date.
How NEC values are checked
Problems use values from 2026 NEC tables (ampacities, conductor areas, motor currents and others). A calculation topic goes live only when the values it uses agree across at least two independent sources. Topics whose values don't meet that rule yet stay off the site until they do.
Why we never print NEC tables
The NEC is a copyrighted work of NFPA. And the exam is open book: the skill being tested is finding the value in your own book. Problems tell you which table to open and your answer is checked against the right value, but we never reproduce the tables.
What we are not
We are not affiliated with TDLR, PSI or NFPA. NEC and National Electrical Code are registered trademarks of NFPA. No question comes from a real exam. Always confirm with TDLR and your PSI bulletin before you test.
