Frequently Asked Questions

Yes — completely free with no account required. All questions include detailed explanations and NEC references.

Most state Journeyman exams have 80–100 questions covering NEC code, wiring methods, branch circuits, motor controls, and load calculations.

Most states require a 70–75% passing score. This practice test uses the same 70% pass threshold so you know where you stand.

Questions are written to the 2023 NEC. Check your state licensing board to confirm which edition your state has adopted.

This test covers basic electrical math and NEC code rules. Make sure you know Ohm's Law (V = I × R), the power formula (P = V × I), and how to read wire ampacity tables. Review NEC 110.26 (working space) and NEC 430.32 (motor overload protection) before you start.
