The Oklahoma Unlimited Electrical Contractor license is the highest-ranking electrical contractor license category in Oklahoma. This classification is designed for contractors who perform electrical contracting work without the limits placed on residential or limited electrical contractor categories. Because the license carries broad contractor responsibility, the exam measures a wide range of electrical knowledge, including code requirements, jobsite safety, installation methods, electrical theory, services, feeders, branch circuits, grounding and bonding, overcurrent protection, conductors, raceways, boxes, special occupancies, low voltage systems, lighting, signs, motors, and transformers.

This online practice question product helps you prepare in an active study format. Instead of only reading the National Electrical Code, OSHA regulations, and Ugly’s Electrical References, you can work through practice questions that help reinforce important topics and build familiarity with exam-style wording. Practice questions are especially useful for open book electrical exams because success depends on both understanding the material and knowing how to locate information efficiently under time pressure.

The Oklahoma Unlimited Electrical Contractor Exam requires more than basic code recognition. Candidates should be comfortable applying NEC rules, using tables, working through calculations, understanding safety requirements, and recognizing how electrical installation rules apply in real project situations. This product gives you a structured way to prepare during your 3-month access period by turning broad reference material into practical review.

Exam Details

The Oklahoma Unlimited Electrical Contractor Exam is administered by PSI for the Oklahoma Construction Industries Board. Candidates must be approved by the State of Oklahoma before scheduling the examination. Once approved, candidates schedule their exam appointment through PSI.

The Unlimited Electrical Contractor examination contains 100 scored items. Candidates are allowed 240 minutes to complete the exam, and the listed passing score is 70% correct. The examination is computer-based and is taken at an approved PSI testing location.

The exam evaluates knowledge needed to perform and manage unlimited electrical contracting work. It covers electrical conductors, fixtures, appliances, apparatus, raceways, conduit, and related electrical equipment used for light, heat, power, data, and communications. It also includes electrical theory, jobsite safety, and code-based installation topics.

Major exam content areas 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, alarms, signaling systems and communications, lighting and signs, safety, motors, and transformers.

Because the exam includes both broad trade knowledge and detailed code application, candidates should prepare with the approved references and practice applying those references to questions. The online practice question format helps support that preparation by giving you repeated exposure to the topics that appear throughout the content outline.

Open Book Test

The Oklahoma Unlimited Electrical Contractor Exam is an open book test. Candidates are responsible for bringing their own approved references to the examination center. For code questions, the examination is based only on the specific code edition listed for the exam.

Reference materials may be highlighted, underlined, and indexed before the examination session. References may not be written in before or during the examination. Candidates may use permanent tabs only. Temporary tabs, including Post-it style notes, are not allowed and must be removed before the exam begins. Candidates are not permitted to bring additional loose papers with approved references.

NEC Handbooks and spiral-bound copies of the National Electrical Code are not allowed in the test center. A silent, non-printing, non-programmable calculator may be used in the examination center. Candidates may also request a magnifying glass at the test center.

Because this is an open book exam, preparation should include reference navigation. Knowing the answer is helpful, but knowing where to find the answer can be just as important during a timed exam. Candidates should practice using the NEC index, article layout, tables, definitions, and cross-references. OSHA and Ugly’s Electrical References should also be reviewed so candidates can quickly identify which book is most useful for a particular question.

Licensing Steps

Oklahoma electrical contractor licensing is handled through the Oklahoma Construction Industries Board. Candidates applying for an electrical contractor license must meet the state’s licensing requirements, submit the required application materials, receive approval to test, schedule the required examination through PSI, and complete the remaining licensing requirements after passing.

All Oklahoma electrical contractors must be an owner, partner, or officer in the electrical firm. The Unlimited Electrical Contractor category is the broadest contractor classification and allows unlimited electrical contracting work within the scope of Oklahoma law and rules.

The general licensing process begins with confirming eligibility for the Unlimited Electrical Contractor license. The applicant then submits the appropriate application and supporting documentation to the Oklahoma Construction Industries Board. After the application is reviewed and the candidate is approved, the candidate schedules and takes the PSI exam. Passing the exam is an important step, but the license must also be properly activated before the contractor engages in electrical contracting work.

Active electrical contractors in Oklahoma must keep required bond and insurance documentation current. Contractor license activation may require a corporate surety bond and proof of commercial general liability insurance naming the Construction Industries Board as the certificate holder. Electrical contractors must also provide proof of satisfactory workers’ compensation coverage upon initial approval and renewal, or provide an affidavit of exemption or self-insurance as authorized under Oklahoma workers’ compensation law.

Maintaining an active license is an ongoing responsibility. Contractors should keep insurance, bond, workers’ compensation compliance, renewal information, and business records current. The business side of contracting matters just as much as passing the examination because electrical contractors are responsible for operating legally, safely, and professionally.

State Requirements

Oklahoma recognizes multiple electrical contractor license categories, including Unlimited Electrical Contractor, Residential Electrical Contractor, and Limited Electrical Contractor. The Unlimited Electrical Contractor category is not limited by the type of electrical contracting work that may be performed, making it the broadest electrical contractor license category in the state.

An Unlimited Electrical Contractor applicant must document 12,000 verifiable hours of on-the-job experience in electrical construction work. Oklahoma requires proof of 4,000 hours of experience as a licensed Unlimited Electrical Journeyman. Of the total required experience, 6,000 hours must be in commercial industrial work obtained while employed by a licensed electrical contractor. Up to 2,000 hours may be satisfied by formal electrical education.

Formal educational experience must be actual classroom hours verified with a transcript. Applicants should prepare complete documentation before applying because the Construction Industries Board determines eligibility before a candidate may schedule the examination.

The Unlimited Electrical Contractor license is connected to contractor-level responsibility. Applicants should understand the difference between contractor authority and journeyman-level work, as well as the state requirements for business status, insurance, bond documentation, workers’ compensation compliance, and license renewal. Candidates should also review Oklahoma’s current electrical statutes, rules, and application materials before submitting licensing documents.
