The complete Journeyman Electrician exam guide

From apprentice to Journeyman Electrician — the licensing path

A Journeyman Electrician license is the credential that lets you work on commercial and residential installations without direct supervision. Every US state runs its own board, but the path looks the same almost everywhere:

1. Log your hours. Most states require 8,000 hours (about 4 years) of documented on-the-job training under a licensed electrician, plus 576–800 hours of related classroom instruction.
2. Submit your application. The state board verifies hours with your employer or apprenticeship sponsor (IBEW, IEC, ABC). Allow 4–8 weeks for processing.
3. Schedule the exam. Once approved, you book a slot through PSI, Prometric, or your state's testing vendor. Fees range from $50 to $200.
4. Pass the written exam. 80–100 questions, typically 4 hours, open-book on the NEC. A passing score is usually 70–75%.
5. Apply for the license. Pay the licensing fee, submit insurance / bonding if your state requires it, and you can work as a Journeyman.

What's actually on the Journeyman Electrician exam?

Exact weightings vary slightly by state, but every Journeyman exam is built around the same eight NEC-heavy buckets. Knowing the weighting tells you exactly where to invest study hours:

• NEC general (Articles 90, 100, 110) — 8–12%. Definitions and general rules. These show up everywhere and reward fast lookups.
• Branch circuits, feeders, services (210, 215, 220, 230) — 18–22%. Load calculations, ampacity, dwelling-unit service sizing. Highest single point bucket on most exams.
• Overcurrent protection (240) — 8–10%. Breaker sizing, conductor protection, tap rules.
• Grounding & bonding (250) — 10–14%. EGC sizing (Table 250.122), grounding electrode conductors. Notoriously fiddly — drill table lookups.
• Wiring methods & materials (300, 310, 314, 392) — 12–15%. Conductor ampacity (310.16), box fill, raceway fill (Annex C / Chapter 9 Table 1).
• Equipment for general use (400, 408, 430, 440) — 10–12%. Motor calcs, AC unit branch circuits, panelboards.
• Special occupancies & equipment (500, 511, 517, 590, 680) — 6–10%. Hazardous locations, healthcare, swimming pools.
• Electrical theory & trade math — 10–15%. Ohm's law, power, voltage drop, three-phase, conduit bending.

Code-book navigation: the single biggest difference between pass and fail

The exam is open-book, but you only get about 3 minutes per question. Candidates who fail almost always know the material — they just can't find the rule fast enough. Build these habits before exam day:

• Tab strategically. Use tabs for Articles 210, 220, 230, 240, 250, 300, 310, 314, 408, 430, and Chapter 9 tables. Avoid over-tabbing — more than 25 tabs slows you down.
• Learn the index, not the article numbers. The NEC index at the back is faster than guessing which article a topic lives in. Practice "find this term in 15 seconds" drills.
• Memorize the table locations for 250.66, 250.122, 310.16, 430.250, and Chapter 9 Table 1. These tables appear on nearly every exam.
• Don't read every word. Scan for the specific clause, exception, or informational note that answers the question. Move on if you can't find it in 90 seconds — flag and return.

An 8-week Journeyman Electrician study plan

• Weeks 1–2: NEC fluency. One hour a day flipping the code book. Read Article 90 and 100 end-to-end. Memorize chapter structure.
• Weeks 3–4: Calculations. Drill conductor ampacity, voltage drop, dwelling-unit service loads, motor circuit sizing. Aim for 30 calc questions a day.
• Weeks 5–6: Grounding, bonding, and special occupancies. Article 250 plus 500, 517, 680. These are the highest-failure topics on the test.
• Week 7: Mixed practice exams. Two timed 4-hour mock exams. Review every wrong answer the same night.
• Week 8: Rest and refresh. Light review, sleep 8 hours, and tab any new lookups you struggled with.

State-specific gotchas

Always confirm your state board's rules — they override anything generic on the internet. A few common pitfalls:

• Texas — 8,000 hours, no formal apprenticeship required. Exam covers TX state amendments alongside the NEC.
• California — ICC-administered exam; you must hold an active ET card and 8,000 hours within the last 5 years.
• Florida — county-issued in many cases rather than state. Check the local building department before booking.
• New York — licensing is by city (NYC, Buffalo, Rochester each run their own board).
