Oklahoma Unlimited Electrical Journeyman Exam: What You Need to Know to Pass in 2026

You've put in the hours. Now it's time to prove it. The Oklahoma Unlimited Electrical Journeyman exam is the final step between you and a license that opens doors across the state. This exam covers 100 scored questions over 240 minutes, and you need to answer 70 of them correctly. It's open book, which helps — but only if you know where to look. This article covers the exam format, every topic area, sample questions, study materials, and tips from people who've been through it.

Oklahoma Unlimited Electrical Journeyman Exam Overview

The Oklahoma Unlimited Electrical Journeyman exam is administered by PSI on behalf of the Oklahoma Construction Industries Board. Here's the basic format:

• Questions: 100 scored items (additional unscored experimental questions may appear and do not count against your score)
• Time limit: 240 minutes (4 hours)
• Passing score: 70% — you need 70 correct answers
• Format: Open book, computer-based at a PSI testing center
• Allowed references: NEC 2023, OSHA 29 CFR Part 1926, and Ugly's Electrical References (any edition)

Your score appears on the screen the moment you finish. No waiting. If you pass, the Oklahoma State Construction Industries Board issues your license. If you don't, you wait 30 days and go again.

Schedule your exam through the exam registration page after you've been approved by the Board. You'll need your Oklahoma Con ID number to set up your PSI account. You can also call PSI at (855) 834-8750.

Topics Covered on the Oklahoma Unlimited Electrical Journeyman Exam

The exam pulls from 13 topic areas. Here's how they're weighted — this tells you where to spend the most study time:

Six topics account for 60 of the 100 questions: General Electrical Knowledge, Electrical Installation Requirements, Services/Feeders/Branch Circuits, Grounding and Bonding, Special Occupancies, and Safety. Get solid on those first.

For calculations, know your Ohm's Law, power formulas, ampacity correction and adjustment factors, load calculations using demand factors, and conduit fill. For Safety, the exam tests OSHA-specific content — lockout/tagout, PPE selection, arc-flash labeling, and fall protection. Know your 29 CFR 1926 references cold.

Sample Questions

Here are five actual-style questions from the Oklahoma Unlimited Electrical Journeyman practice test pool. Work through them and see how you do — answers are NOT shown here. Take our free practice exam to check your answers and get more.

Question 1 — Conductors and Cables (Medium)

You are installing conductors in raceways. At what conductor size must conductors be stranded rather than solid when installed in raceways?

• A) 10 AWG and larger
• B) 8 AWG and larger
• C) 4 AWG and larger
• D) 6 AWG and larger

This question tests NEC rules on conductor construction — specifically where solid conductors are no longer permitted in raceways.

Question 2 — Conductors and Cables (Hard)

Adjustment factors for more than three current-carrying conductors in a raceway do NOT apply to Type AC or Type MC cables without an overall outer jacket when certain conditions are met. One condition is that not more than how many current-carrying conductors are installed without maintaining spacing?

• A) 12
• B) 20
• C) 16
• D) 24

This tests a specific exception in the ampacity adjustment rules — the kind of detail that separates candidates who read carefully from those who skim.

Question 3 — Services, Feeders, and Branch Circuits (Hard)

A journeyman is calculating feeder loads for a multifamily dwelling with 12 units using the optional method. Each unit has electric cooking equipment and electric space heating. What demand factor from the optional calculation table applies to the 12-unit building?

• A) 40%
• B) 45%
• C) 41%
• D) 43%

Load calculations using the optional method require knowing which table to look up and how to read it. Practice this one.

Question 4 — Safety (Medium)

You are a journeyman electrician working on a construction project. A coworker points out that a hole cover on the floor has come loose. According to fall protection requirements, how must covers for holes in floors, roofs, and other walking/working surfaces be marked to warn employees of the hazard?

• A) Painted bright orange on all surfaces
• B) Stenciled with the word "DANGER" in red letters
• C) Color coded or marked with the word "HOLE" or "COVER"
• D) Marked with reflective tape around the perimeter

Straight from 29 CFR 1926. Know your OSHA fall protection requirements.

Question 5 — Services, Feeders, and Branch Circuits (Hard)

You are sizing the feeder overcurrent protection for a panel that supplies three motors. The largest motor's branch-circuit overcurrent device is rated at 90 amperes, and the other two motors have full-load currents of 14 amperes and 10 amperes respectively. What is the maximum permitted feeder overcurrent protective device rating?

• A) 100 amperes
• B) 110 amperes
• C) 125 amperes
• D) 114 amperes

This is a multi-step calculation from NEC Article 430. Motor feeder sizing trips up a lot of people — make sure you know the formula.

Study Materials

This is an open-book exam, so you need the right books — and you need to know them well enough to find answers fast.

Required references:

• NEC 2023 — Your primary reference. The exam is built around it. Tab it, highlight it, and know which articles cover what.
• OSHA 29 CFR 1926 — Required for the Safety topic, which carries 10 exam items. Don't skip this one.
• Ugly's Electrical References 2020 — A compact field reference with tables, formulas, and quick lookup info. Any edition is allowed.

Recommended supplies:

• Sharpie Tank Highlighters — Bright fluorescent ink, chisel tip, and a large ink supply. You'll use a lot of highlighter marking up the NEC. These come in 12 assorted colors so you can color-code by topic.
• Redi-Tag Permanent Colored Tabs — 100 permanent adhesive tabs in five colors. Use them to mark key articles and tables so you can find them in seconds on exam day. Important: Only permanent tabs are allowed. Post-It notes and temporary tabs will get you turned away at the door.

Note: You may highlight or underline in your references, but you cannot write in them or insert loose papers before or during the exam.

Study Tips

Give yourself three to six weeks. Use the official exam bulletin as your roadmap and work through each topic area systematically.

Speed matters more than memorization. This is open book, so the skill you're actually building is finding information fast. Practice locating tables, articles, and exceptions under time pressure. Know Table 310.16, Table 250.66, and your conduit fill tables by heart — or at least know exactly where they are.

Set your practice bar at 80%. The real passing score is 70%, but if you're hitting 80% or higher on practice exams, you have a comfortable margin when nerves hit on test day.

Work through every question once. Answer what you know, skip what you don't, and come back. Don't let one hard question eat 10 minutes of your time. Flag it and move on — same approach you'd use on our practice exams.

Keep your head. Some anxiety is normal. If you feel stuck, stop, breathe, reset. If the test center allows a break, take it. Just remember the clock keeps running.

Focus your heaviest prep on the six topics carrying 10 items each — those alone account for 60% of your score.
