Oklahoma maintains statewide electrical licensing through the Oklahoma Construction Industries Board. The state offers several journeyman classifications, including Unlimited Electrical Journeyman and Residential Electrical Journeyman. For electricians seeking broad journeyman authority, the Unlimited Electrical Journeyman classification is the primary statewide journeyman credential.

The current Oklahoma Unlimited Electrical Journeyman examination is administered by PSI. The exam contains 100 scored questions, allows four hours, requires a minimum score of 70%, and is open book. Oklahoma's current examination questions are based on the 2023 National Electrical Code as revised and adopted by the Oklahoma Uniform Building Code Commission.

This package is intentionally based on the newer 2026 NEC. It provides current National Electrical Code education while helping students strengthen navigation, calculations, electrical theory, and trade knowledge. Candidates preparing specifically for Oklahoma's currently administered examination should also work directly with the 2023 NEC because that remains the code edition identified for current test questions.

Exam Details

The Oklahoma Unlimited Electrical Journeyman examination is part of the statewide licensing program administered by the Oklahoma Construction Industries Board. Applicants must first meet the applicable experience requirements and receive approval from the state before scheduling the examination through PSI.

The current Unlimited Electrical Journeyman examination contains 100 scored questions. Candidates receive 240 minutes, or four hours, to complete the examination and must earn at least 70% to pass.

PSI may also include up to 10 experimental questions. These questions are not scored and are used to evaluate potential future examination content.

The current examination outline includes 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, Alarms, Signaling Systems, and Communications; Lighting and Signs; Safety; and Motors and Transformers.

General Electrical Knowledge includes voltage, current, resistance, series and parallel circuits, electrical power, AC theory, three-phase theory, troubleshooting, NEC navigation, definitions, temporary wiring, cranes and hoists, elevators, and escalators.

Services, Feeders, and Branch Circuits includes services, voltage drop, services over 600 volts, feeders, outside branch circuits and feeders, branch circuits, space-heating circuits, snow-melting and pipe-heating circuits, and air-conditioning and refrigeration equipment.

The exam also gives significant attention to wiring methods. Candidates should be familiar with raceways, cables, conductor selection, conduit fill, boxes, box fill, cable trays, wireways, and other installation methods commonly addressed by the NEC.

Open Book Test

The Oklahoma Unlimited Electrical Journeyman examination is an open-book test. Candidates may bring the approved references identified in the current PSI examination bulletin.

The current code reference for the examination is the 2023 edition of NFPA 70, National Electrical Code, as revised and adopted by the Oklahoma Uniform Building Code Commission. Oklahoma began testing on the 2023 NEC on December 14, 2024, after adopting the 2023 NEC as the statewide minimum electrical code effective September 14, 2024.

The current testing rules state that NEC Handbooks and spiral-bound copies of the National Electrical Code are not allowed in the examination center. Candidates are responsible for bringing their approved references.

Authorized references may be highlighted, underlined, and indexed before testing. Permanent tabs are allowed. Temporary removable tabs such as Post-it-style markers are not permitted. Written notes in the references are not permitted under the current PSI rules.

The NEC tabs included with this package are intended to help organize your personal 2026 NEC during study. Candidates preparing a 2023 NEC for the actual Oklahoma exam should follow PSI's current reference-material rules and use permanent tabs that comply with those requirements.

Open-book testing still requires fast navigation. With 100 scored questions and four hours, candidates average less than two and one-half minutes per scored question. Effective preparation means recognizing the subject, identifying the likely NEC article or table, locating the applicable rule, and applying it accurately.

State Requirements

Oklahoma requires an Unlimited Electrical Journeyman applicant to document 8,000 verifiable hours of on-the-job experience in electrical construction while working as a registered apprentice under the direct supervision of a licensed journeyman or licensed electrical contractor.

At least 4,000 hours must involve commercial or industrial electrical work. This requirement reflects the broad scope of the Unlimited Electrical Journeyman classification and helps ensure applicants have experience beyond limited residential installations.

Oklahoma allows up to 2,000 hours of qualifying formal electrical education to substitute for part of the experience requirement. Educational experience must consist of actual classroom hours and must be documented with an official transcript.

Oklahoma also offers a Residential Electrical Journeyman classification. That classification requires 4,000 verifiable hours of qualifying electrical construction experience as a registered apprentice, and up to 1,000 hours may be satisfied by qualifying formal electrical education. Residential journeyman authority is limited to the scope established for residential electrical work.

Apprentices working toward Oklahoma electrical licensing must work for an active licensed Electrical Contractor and must maintain proper apprentice registration. Oklahoma currently allows no more than three apprentices to be directly supervised by one Journeyman or Contractor.

After becoming licensed, Oklahoma Electrical Journeymen must complete 12 hours of approved continuing education during each three-year period preceding license expiration. Six hours must cover codes and revisions adopted by the Oklahoma Uniform Building Code Commission. The remaining hours may address subjects such as electrical theory, calculations, wiring methods, grounding and bonding, motors, transformers, control systems, alternative energy, electrical safety, and electrical licensing rules.

Oklahoma also maintains Journeyman Electrician reciprocity agreements with Alaska, Arkansas, Colorado, Idaho, Iowa, Montana, Nebraska, South Dakota, Texas, and Wyoming. Reciprocity is subject to Oklahoma's current requirements, including minimum license history and application review.

The statewide minimum commercial electrical code currently remains the 2023 NEC with Oklahoma amendments. The Oklahoma Uniform Building Code Commission has begun the process of considering the 2026 NEC, but the 2023 NEC remains the adopted statewide minimum code as of August 2026.

Review Overcurrent Protection. Study the relationships among conductors, overcurrent devices, equipment protection, branch circuits, feeders, motors, and other electrical installations.

Spend time on Conductors and Cables. Review conductor selection, underground conductors, vertical installations, armored cable, metal-clad cable, nonmetallic-sheathed cable, service-entrance cable, underground feeder cable, and other cable types covered in the current outline.

Practice Raceways and Boxes. Study RMC, EMT, IMC, RNC, FMC, LFMC, LFNC, wireways, gutters, cable trays, raceway fill, box sizing, and box-fill calculations.

Review Special Occupancies and Equipment. The current examination includes hazardous locations, commercial garages, fuel-dispensing facilities, health-care facilities, places of assembly, mobile homes, recreational vehicle parks, floating buildings, pools, fountains, and hot tubs.

Include Low Voltage and Communications. Study signaling circuits, communications circuits, equipment operating at 50 volts or less, fiber optics, photovoltaics, fire alarms, emergency systems, and communications wiring.

Review Lighting and Signs. Practice requirements involving luminaires, grounding, wiring, recessed fixtures, low-voltage lighting, neon lighting, and electric signs.

Study Motors and Transformers. Motor circuits can combine conductor sizing, overload protection, short-circuit protection, disconnecting means, controls, and calculations. Transformer questions also require both electrical theory and code knowledge.

Do not overlook Safety. The Oklahoma exam includes jobsite sanitation, PPE, excavation safety, emergency plans, ventilation, first aid, ladders, scaffolds, fall protection, signs, tools, workplace illumination, toxic materials, and material handling.

Use the Calculations Study Guide actively. Work through problems step by step instead of simply reading completed solutions. Repetition is especially useful for load calculations, conductor sizing, raceway fill, box fill, motors, transformers, and electrical theory.

Use the NEC tabs during preparation. Tabs can help you build a visual map of your 2026 NEC. For actual Oklahoma exam preparation, repeat navigation exercises with the 2023 NEC authorized by PSI.

Use the Master Study Guide for structure. Follow an organized sequence of electrical topics instead of opening random code articles. Track weak areas and return to them regularly.

Use flash cards for repeated review. Flash cards can reinforce formulas, electrical terminology, code concepts, trade knowledge, and theory during shorter study periods.

Watch live and recorded instructor-led videos. Guided instruction provides another way to work through NEC organization, calculations, and difficult electrical concepts. Recorded material can be revisited after practice testing reveals weaker topics.

Complete simulated practice exams regularly. Practice testing helps combine knowledge, calculations, code navigation, and time management. Review missed questions and determine whether the difficulty came from electrical theory, mathematics, NEC research, safety requirements, or misunderstanding the question.
