The Oklahoma Limited Electrical Contractor Exam measures a candidate’s knowledge of the design, plan, 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. Because the exam covers a wide range of electrical subjects, preparation should include both code navigation and practical problem solving.
This online practice question product helps you study in an active format. Instead of only reading the National Electrical Code, OSHA construction safety regulations, and Ugly’s Electrical References, you can test your understanding through questions that support topic recognition, reference navigation, and applied exam preparation. Practice questions are especially useful for open book electrical exams because success depends on knowing the material and being able to locate information efficiently under time pressure.
The Oklahoma Limited Electrical Contractor Exam is not limited to one narrow code topic. It includes general electrical knowledge, installation requirements, services, feeders, branch circuits, overcurrent protection, grounding and bonding, conductors and cables, raceways and boxes, special occupancies and equipment, low voltage systems, lighting, signs, safety, motors, and transformers. This product gives you a structured way to prepare for those tested areas with practical review during your 3-month access period.
The Oklahoma Limited 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 Limited 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 tests knowledge of electrical conductors, fixtures, appliances, apparatus, raceways, conduit, and related equipment used for light, heat, power, data, and communications. The exam also includes jobsite safety and electrical theory topics, so preparation should include both code-book familiarity and practical trade knowledge.
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.
During the computer exam, candidates answer questions on screen and manage their time within the allowed testing period. Score results are provided after the examination. Candidates who pass receive a successful notification, and candidates who do not pass receive diagnostic information showing strengths and weaknesses by examination type.
The Oklahoma Limited 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 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 practice locating information in the NEC, OSHA material, and Ugly’s Electrical References. Strong preparation is not only about memorizing rules. It is also about knowing where to look, understanding how code sections are organized, and recognizing which reference is most useful for a specific question.
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.
A Limited Electrical Contractor must be an owner, partner, or officer in an electrical firm. This license category is different from a journeyman license because it relates to contracting authority and business responsibility. Oklahoma also states that a Limited Electrical Contractor is prohibited from engaging in the work of an apprentice or journeyman electrician.
The general process begins with confirming that the applicant meets the Limited Electrical Contractor requirements. The applicant then submits the appropriate application to the Oklahoma Construction Industries Board with the required documentation. After approval, the candidate schedules and takes the PSI exam. Passing the examination is an important licensing step, but contractor license activation may also require bond, insurance, and workers’ compensation compliance documentation.
Active electrical contractors in Oklahoma must keep required bond and insurance documentation current. The Oklahoma Construction Industries Board must be listed as a certificate holder for required insurance coverage. Failure to keep current insurance can cause a license to become inactive, and contracting without current insurance and an active license is a violation.
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. These requirements are part of operating as an active contractor and maintaining compliance after the examination is passed.
Oklahoma recognizes multiple electrical contractor license categories, including Unlimited Electrical Contractor, Residential Electrical Contractor, and Limited Electrical Contractor. The Limited Electrical Contractor category has specific requirements related to business status, education, and experience.
A Limited Electrical Contractor must be an owner, partner, or officer in an electrical firm. The applicant must have a degree in Electrical Engineering from an accredited college or university plus 8,000 hours of electrical experience in field construction, electrical estimating, or electrical project management in commercial or industrial electrical work, or must verify 16,000 hours of experience in the electrical trade performing electrical work, estimating, or project management in commercial or industrial work.
Educational experience must be verified with an official transcript when used to satisfy state requirements. Applicants should prepare complete documentation before applying because the Construction Industries Board determines eligibility before a candidate may schedule the examination.
Oklahoma electrical licensing requirements are designed to separate contractor-level responsibility from journeyman-level work. A Limited Electrical Contractor license is connected to business and contracting authority, while journeyman work is performed under the rules that apply to journeyman electricians. Candidates should understand the limits of the license category before applying and before offering electrical contracting services.
The Oklahoma Limited Electrical Contractor Exam includes 13 major subject areas. General knowledge covers permits and inspections, preservation of structural integrity, needs analysis, and estimating.
