The examination evaluates a candidate's knowledge of the design, planning, layout, installation, repair, and alteration of electrical conductors, fixtures, appliances, apparatus, raceways, conduit, and related electrical equipment used for light, heat, power, data, and communications in a supervised environment.

General Knowledge includes practical subjects such as permits and inspections, preservation of structural integrity, needs analysis, and estimating. Candidates should understand how electrical work relates to the broader construction process and the requirements that apply before, during, and after an installation.

General Electrical Knowledge includes voltage, current, resistance, electrical power, series and parallel circuits, AC theory, three-phase systems, troubleshooting, temporary wiring, and NEC terminology. Candidates should develop a solid understanding of electrical theory because these concepts support calculations and practical code applications throughout the examination.

Services, Feeders, and Branch Circuits are important preparation areas. Candidates should review service installations, feeder requirements, outside branch circuits and feeders, branch circuits, voltage drop, electric heating equipment, air-conditioning equipment, and refrigeration equipment.

Overcurrent Protection requires candidates to understand how conductors and equipment are protected from excessive current. Preparation should include conductor ampacity, circuit ratings, overcurrent protective devices, and the NEC rules governing their application.

Grounding and Bonding is another important examination area. Candidates should understand grounding electrode systems, grounding electrode conductors, equipment grounding conductors, bonding methods, conductor sizing, and the purpose of grounding and bonding within electrical systems.

Conductors and Cables can include conductor selection and multiple wiring methods. Candidates should become familiar with the NEC requirements affecting conductor ampacity, insulation, underground installations, cable types, conductor identification, and installation conditions.

Raceways and Boxes include rigid metal conduit, intermediate metal conduit, electrical metallic tubing, rigid nonmetallic conduit, flexible raceways, conduit fill, box fill, pull boxes, fittings, wireways, auxiliary gutters, and related electrical enclosures.

Additional examination areas include Special Occupancies and Equipment, Low Voltage and Communications, Lighting and Signs, Safety, Motors, and Transformers. Candidates should prepare for both the technical principles behind these systems and the code requirements that apply to their installation.

Open Book Test

The Oklahoma Unlimited Electrical Journeyman examination is an open book test. Approved references may be used during the examination according to the testing provider's examination-center rules.

The references for the technical examination include the National Electrical Code, NEC, 2023, Code of Federal Regulations - 29 CFR Part 1926 (OSHA), and Ugly's Electrical References.

The 2023 National Electrical Code is the central reference for electrical code questions. Candidates should become familiar with the organization of the NEC, including chapters, articles, definitions, tables, and specialized installation requirements.

The OSHA reference supports preparation for construction safety questions. Candidates should know how to locate requirements involving personal protective equipment, ladders, scaffolds, fall protection, excavation hazards, tools, material handling, and other workplace safety subjects.

Ugly's Electrical References provides a compact resource for electrical formulas, conversions, calculations, tables, conductor information, motor information, and other commonly referenced electrical data.

Open-book testing does not eliminate the need for preparation. With 100 scored questions and 240 minutes, candidates need to manage their time carefully. Searching through an unfamiliar code book for every question can make the examination more difficult.

A better approach is to identify the subject first. If the question involves grounding or bonding, move toward the applicable NEC provisions. If it involves construction safety, determine whether 29 CFR Part 1926 contains the required information. If the question involves a formula or commonly used electrical calculation, Ugly's Electrical References may provide a useful starting point.

Practice using all three references throughout preparation. Repeated reference navigation can help candidates create a stronger mental map of where important electrical information is located.

Licensing Steps

The Oklahoma Construction Industries Board administers electrical journeyman licensing, including the Unlimited Electrical Journeyman classification.

The licensing path generally begins with gaining qualifying electrical construction experience while working as a registered apprentice under the required supervision. Candidates should maintain accurate records of qualifying work and apprenticeship experience.

An applicant for the Oklahoma Unlimited Electrical Journeyman classification must document 8,000 verifiable hours of on-the-job experience in the electrical construction trade as a registered apprentice under the direct supervision of a licensed Journeyman or licensed Electrical Contractor.

Up to 2,000 hours of the experience requirement may be satisfied through qualifying formal electrical education. Educational experience used toward licensing must meet Oklahoma requirements and be supported by appropriate documentation.

After completing the applicable experience requirements, the applicant submits the appropriate electrical journeyman application. Once the application is approved and examination eligibility is established, the candidate proceeds with the authorized testing process.

The candidate then completes the Oklahoma Unlimited Electrical Journeyman examination. Successful completion of the examination is one part of satisfying the requirements for journeyman licensure.

After completing the licensing process, an Unlimited Electrical Journeyman works for an active licensed Electrical Contractor. Journeyman work provides additional professional experience and can also support electricians who later pursue contractor-level licensing.

State Requirements

The Oklahoma Unlimited Electrical Journeyman classification is intended for experienced electrical tradespeople who have completed the applicable experience requirements and demonstrated the technical knowledge required for journeyman-level electrical work.

The standard experience pathway requires 8,000 hours of qualifying electrical construction experience. This experience is gained as a registered apprentice under the direct supervision of a licensed Journeyman or licensed Electrical Contractor.

Oklahoma allows qualifying formal electrical education to satisfy up to 2,000 hours of the overall experience requirement. Candidates using education toward qualification should maintain the records needed to establish their qualifying classroom experience.

Proper apprentice registration is important while gaining Oklahoma experience that will later be used for journeyman licensure. Candidates should maintain accurate employment and experience records throughout their apprenticeship period.

An Unlimited Electrical Journeyman performs electrical work while employed by an active licensed Electrical Contractor. The journeyman classification is different from an Electrical Contractor license, which carries separate contractor-level experience, business, insurance, and licensing responsibilities.

Oklahoma electrical licensees must also maintain the applicable continuing education requirements. Electrical Journeymen and Electrical Contractors complete 12 hours of approved continuing education during the applicable three-year or 36-month licensing period.

Continuing education helps licensed electricians remain familiar with electrical code changes and other industry subjects such as wiring methods, calculations, grounding and bonding, motors, transformers, control systems, electrical safety, and regulatory requirements.
