The Exam · 120 Questions · 4 Hours · Built to the 2023 NEC

Train above the line.

A full 120-question master electrician practice exam in a timed reader — modeled on the structure used by Texas (TDLR/PSI) and cross-checked against the ICC national standard. Four hours on the clock. The pass bar is set at 75% — deliberately above the 70% most jurisdictions require — because we’d rather you walk in over-prepared than on the line.

How the reader works

  • The clock runs like the real one — four hours, always visible, never hidden.
  • Jump to any question, flag the hard ones, come back — manage the exam instead of letting it manage you.
  • Answer choices shuffle on every attempt, so you’re learning the material, not the letter positions.
  • On submit: your score, the pass line, and a score-by-topic report that shows exactly which of the fifteen domains needs another evening.
  • Every question carries a full rationale with its 2023 NEC citation — the why behind every answer, right or wrong.

What 120 questions cover

The bank is built to a published blueprint across fifteen domains — from definitions and conductor sizing through services, grounding, motors, transformers, special occupancies, and renewable energy, closing with integrative load calculations that pull it all together. The weighting mirrors how master exams actually distribute their questions: services, branch circuits, and grounding carry the load, because that’s where the real exam lives.

Verified, question by question

Every one of the 120 answers was audited against the 2023 NEC before release — 120 of 120 confirmed. When a practice question teaches you something here, you can trust it’s teaching you the Code, not somebody’s recollection of it.
