Preparing for your Oklahoma Journeyman Electrician license? This guide covers the Construction Industries Board licensing process, current PSI examination details, electrical experience requirements, official exam subjects, approved books, electrical calculations, reference navigation, and related study products available from Contractor Exam Preps.
Electrical work is one of those careers where being almost correct is not good enough.
A conductor needs the proper ampacity. An overcurrent device must suit the circuit. Grounding and bonding must be correct. Electrical equipment must be installed safely.
And when you are staring at a complicated motor-control problem, guessing is not an approved electrical formula!
Oklahoma requires electricians to demonstrate their knowledge and experience before receiving a journeyman license.
The licensing process is regulated by the Oklahoma Construction Industries Board, commonly called CIB.
PSI administers the licensing examinations for approved candidates.
An Oklahoma Journeyman Electrician is an individual licensed to perform electrical work within the scope of the journeyman category and applicable supervision requirements.
The state offers different electrical journeyman categories.
The most widely applicable advanced journeyman credential is Unlimited Electrical Journeyman.
Oklahoma also licenses Residential Electrical Journeymen and has a separate Refinery Electrical Journeyman category.
Each category has its own eligibility requirements and permitted work scope.
The Unlimited Electrical Journeyman examination tests knowledge involving residential, commercial, and industrial electrical installations.
This article focuses primarily on Unlimited Electrical Journeyman because it is the broader examination.
No. Oklahoma has separate journeyman and electrical contractor license categories.
The Journeyman Electrician license establishes an individual's qualification to perform authorized electrical work within a supervised employment structure.
An Electrical Contractor license involves separate contractor qualifications and business responsibilities.
Oklahoma's contractor categories include Unlimited Electrical Contractor, Residential Electrical Contractor, and Limited Electrical Contractor.
The contractor examination and Business and Law requirements should not be confused with the journeyman examination.
Working as a journeyman may help someone gain additional experience toward a contractor license.
The Oklahoma Construction Industries Board regulates electrical licensing.
CIB handles apprentice registration, journeyman and contractor licenses, examination eligibility, renewal, continuing education, and applicable trade rules.
Applicants must apply to CIB and receive approval before scheduling their PSI examination.
After approval, candidates contact PSI to choose an examination date and location.
The official Oklahoma PSI Candidate Information Bulletin effective September 11, 2026 lists 100 scored questions for Unlimited Electrical Journeyman.
Candidates have 240 minutes, or four hours.
The passing score is 70%.
That means 70 correct answers are needed on the scored examination.
PSI may also administer up to ten additional experimental questions.
Those questions do not count toward the final score.
They are used to help develop future examinations.
Yes. The examination is open book.
However, only the approved reference materials are allowed.
The current reference list includes the 2023 National Electrical Code, OSHA construction safety regulations, and Ugly's Electrical References.
Candidates must provide their own approved books.
PSI does not allow the NEC Handbook or spiral-bound editions of the NEC.
Permanent tabs and prior highlighting are allowed under the reference rules.
Temporary tabs, handwritten notes, and loose papers are prohibited.
Oklahoma's current PSI Electrical Journeyman examination uses the 2023 National Electrical Code, as revised and adopted by the Oklahoma Uniform Building Code Commission.
The September 2026 PSI bulletin continues to identify that edition.
Oklahoma made building code updates effective September 14, 2026, but the published electrical exam reference remains the 2023 NEC.
Some study products are based on the newer 2026 NEC.
Those products may help electricians learn updated material, but candidates should use the code edition required by their official Oklahoma examination.
The 2025 Complete Journeyman Electrician Exam Prep Package based on the 2023 NEC is a closer code-edition match than a 2026 NEC bundle.
The official PSI examination contains thirteen scored subject categories.
These categories total 100 scored questions.
The exam tests many electrical subjects rather than one large specialty.

The exam covers thirteen subject areas.
These include General Knowledge, General Electrical Knowledge, Electrical Installation Requirements, Services, Feeders and Branch Circuits, Overcurrent Protection, Grounding and Bonding, Conductors and Cables, Raceways and Boxes, Special Occupancies and Equipment, Low Voltage and Communications, Lighting and Signs, Safety, and Motors and Transformers.
The examination covers a broad range of electrical skills.
Electrical theory is an important starting point.
Students should understand voltage, current, resistance, power, and AC circuits.
They should practice Ohm's law and basic electrical calculations.
Services, feeders, and branch circuits are another important area.
Electricians need to understand how power is distributed and how circuits are sized.
Conductor ampacity, load calculations, and overcurrent protection should be practiced regularly.
Grounding and bonding deserve special attention.
These requirements support electrical safety and effective fault-current paths.
Students should study NEC Article 250 and practice equipment grounding conductor and grounding electrode conductor sizing.
Raceways and boxes also require careful review.
Practice conduit fill, box fill, and the differences between major wiring methods.
Special occupancies and equipment cover installations with requirements beyond ordinary building wiring.
Examples include swimming pools, health care areas, and hazardous locations.
Lighting and signs account for ten scored questions.
Motor and transformer subjects involve special electrical rules and equipment protection.
Safety includes OSHA construction requirements and practical jobsite hazards.
Students should use the official PSI subject outline to balance their preparation.
One common study mistake is spending nearly all available time on the electrical work already performed every day.
An electrician who is excellent at installing residential branch circuits may still need more practice with motors, transformers, or special occupancies.
Likewise, an experienced industrial electrician may need extra review of lighting, services, and residential wiring requirements.
Open-book testing should be treated as a skill.
Students need to find information quickly in the NEC and other approved references.
They should practice identifying the subject, locating the relevant rule, checking nearby exceptions or tables, and applying the answer correctly.
Timed practice helps build these habits.
