The journeyman electrician exam is an open-book test against the National Electrical Code. It's less about whether you're a good electrician and more about whether you can find a rule in the code book fast and run the standard calculations cleanly under time pressure. Expect questions on code navigation and definitions, conductor ampacity, branch circuits, overcurrent protection, grounding and bonding, box and conduit fill, services and feeders, motors, and voltage drop.
Which NEC edition Iowa uses
Iowa currently references the 2023 NEC for journeyman licensing. Editions get adopted on each state's own timeline, so confirm the exact code year with your licensing board before you sit. Our question bank covers both the 2023 and 2026 editions, and you can switch between them anytime. More on NEC editions →

- Tab your code book so you can land on any article in seconds.
- Drill timed code-lookup questions until speed is automatic.
- Practice the calculations: box fill, conduit fill, ampacity, voltage drop, dwelling loads.
- Take full-length, timed mock exams so the real thing feels like a rerun.
