2023 Oklahoma Master Electrician Exam Prep Study Package Includes Instructor-Led NEC Course (Based on the 2023 NEC)

Prepare for Oklahoma’s highest general electrical contractor licensing examination with a comprehensive study package built around the 2023 National Electrical Code. This Oklahoma Master Electrician Exam Prep Study Package combines the NFPA 70 National Electrical Code, 2023 Edition, NEC tabs, master electrician flash cards, a Master Electrician Study Guide, a Calculations Study Guide, an online instructor-led NEC course, simulated practice exams, an NEC overview, and live and recorded instructional videos.

Oklahoma does not use the formal license title “Master Electrician” for its highest statewide electrical credential. The Oklahoma Construction Industries Board licenses electrical contractors, with the Unlimited Electrical Contractor classification representing the highest-ranking general electrical license. Unlimited Electrical Contractors are not limited in the type of electrical contracting work they may perform.

Preparing for the Oklahoma Unlimited Electrical Contractor examination requires more than field experience. Candidates must understand electrical theory, National Electrical Code requirements, installation methods, services, feeders, grounding and bonding, conductors, motors, transformers, special occupancies, calculations, safety requirements, permits, inspections, and other subjects associated with professional electrical contracting.

This package provides an organized preparation system for developing those skills. Candidates can read structured study material, work through advanced electrical calculations, use flash cards for active recall, follow instructor-led NEC training, practice navigating the code book, and measure their progress through simulated practice exams.

The included NFPA 70 National Electrical Code, 2023 Edition, is directly relevant to current Oklahoma testing. Oklahoma adopted the 2023 NEC as the statewide minimum electrical code, with state amendments, and current Oklahoma electrical licensing examinations use the 2023 NEC for code questions.

The NEC tabs help organize major articles and subject areas for faster reference navigation. Repeated use of a tabbed code book can help candidates develop familiarity with definitions, services, branch circuits, feeders, conductors, grounding and bonding, motors, transformers, wiring methods, special equipment, special occupancies, and commonly used tables.

The Master Electrician Study Guide provides a structured approach to advanced electrical preparation. The Calculations Study Guide supports focused practice with electrical theory, services, feeders, conductor sizing, motors, transformers, voltage drop, raceway fill, box fill, and other calculation-based subjects.

Master electrician flash cards provide a convenient way to reinforce formulas, terminology, definitions, electrical relationships, and code concepts. The online course adds a guided NEC overview, live instructor-led videos, recorded lessons, and simulated practice exams so students can combine independent study with organized instruction.

Exam Details

The Oklahoma Unlimited Electrical Contractor examination is administered by PSI for the Oklahoma Construction Industries Board. Candidates must first receive examination eligibility from the Construction Industries Board before scheduling the test with PSI.

The Unlimited Electrical Contractor examination contains 100 scored questions. Candidates are allowed 240 minutes, or four hours, to complete the examination. A score of 70 percent is required to pass.

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 equipment using electrical energy for light, heat, power, data, and communications.

General knowledge topics can include permits and inspections, preservation of structural integrity, needs analysis, and estimating. These subjects reflect the broader responsibilities of an electrical contractor who must understand both technical installation requirements and the practical management of electrical work.

General electrical knowledge includes voltage, current, resistance, electrical power, series circuits, parallel circuits, combination circuits, alternating-current theory, three-phase electrical theory, troubleshooting, electrical testing, NEC terminology, temporary wiring, cranes, hoists, elevators, and escalators.

Electrical installation requirements may include approved equipment and wiring methods, branch circuits, feeders, services, grounding and bonding, conductor protection, raceways, cable systems, boxes, cabinets, enclosures, overcurrent protection, and equipment installation.

Master-level preparation should also include motors, motor circuits, transformers, generators, utilization equipment, control devices, special occupancies, special equipment, hazardous locations, and installations with additional safety requirements.

Calculations are an important part of electrical contractor preparation. Candidates should practice service and feeder loads, conductor ampacity, demand factors, voltage drop, motors, transformers, grounding conductors, raceway fill, box fill, and other electrical mathematics that require both formula knowledge and NEC research.

The simulated practice exams included with this package help candidates become accustomed to exam-style technical questions. Practice results can identify weaknesses in code navigation, calculations, theory, installation rules, or time management before the official examination.

Open Book Test

The Oklahoma Unlimited Electrical Contractor examination is an open-book test. Candidates may bring the reference materials approved for the examination by PSI and the Oklahoma Construction Industries Board.

The NFPA 70 National Electrical Code, 2023 Edition, as revised and adopted by the Oklahoma Uniform Building Code Commission, is an approved examination reference. The 2023 NEC included with this package therefore supports preparation using the code edition currently identified for the Oklahoma Unlimited Electrical Contractor examination.

NEC Handbooks and spiral-bound copies of the National Electrical Code are not permitted in the testing center. Candidates should use an acceptable bound copy of the approved NEC edition.

Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs are permitted. Temporary tabs such as Post-It notes are not allowed and must be removed before testing begins.

References may not contain handwritten material, and candidates may not write in approved reference books during the examination. Additional loose papers are not permitted with the approved references.

A silent, nonprinting, nonprogrammable calculator is allowed. Candidates should practice calculations with a calculator that operates within these restrictions so the testing environment feels familiar.

An open-book examination still requires strong preparation. With 100 scored questions and four hours available, candidates cannot rely on searching through the entire code book for every answer. Effective preparation means recognizing the subject, identifying the likely NEC article or table, and locating the applicable requirement efficiently.

The included NEC tabs are useful for building these navigation habits. Candidates should practice using the table of contents, index, Article 100 definitions, chapter organization, tables, exceptions, and cross-references while completing study questions and simulated exams.

Licensing Steps

Begin by determining whether the Oklahoma Unlimited Electrical Contractor classification matches your licensing goal. This classification is the highest-ranking general electrical contractor license and is not limited by the type of electrical contracting work that may be performed.

Applicants for the Unlimited Electrical Contractor classification must document 12,000 hours of qualifying on-the-job experience in electrical construction work.

Of those hours, applicants must provide proof of 4,000 hours of experience as a licensed Unlimited Electrical Journeyman. At least 6,000 hours of the qualifying experience must involve commercial or industrial work obtained while employed by a licensed electrical contractor.

Up to 2,000 hours of the total experience requirement may be satisfied through qualifying formal electrical education. Educational credit must be based on actual classroom hours documented through appropriate school records.

Complete the electrical license application and submit the required experience verification to the Oklahoma Construction Industries Board. The Board reviews the application and determines whether the candidate satisfies the eligibility requirements for the contractor examination.

Once approved, follow the PSI instructions to schedule the Unlimited Electrical Contractor examination. Candidates may select an available testing center and appointment through the PSI testing program.

Build a study schedule before the examination. Begin with the NEC overview and organize the included 2023 National Electrical Code using the supplied tabs. Practice moving quickly between major chapters, articles, tables, definitions, and commonly tested subjects.

Work through the Master Electrician Study Guide in manageable sections. Complete the Calculations Study Guide with the NEC, calculator, and written work available so each mathematical problem can be solved systematically.

Use the flash cards for short active-recall sessions throughout the week. Attend live instructor-led training and use recorded videos to revisit difficult subjects such as grounding and bonding, services, motors, transformers, conductor sizing, or calculations.

Complete simulated practice exams under timed conditions. Review every incorrect answer and questions that required excessive time. Continue targeted study until code navigation, calculations, and technical knowledge become more consistent.

After passing the examination, complete the remaining Oklahoma licensing requirements and maintain the business relationship required for an electrical contractor license. Oklahoma electrical contractors must be an owner, partner, or officer in the electrical firm with which the contractor license is associated.

State Requirements

Electrical licensing in Oklahoma is administered by the Oklahoma Construction Industries Board under the Electrical License Act and the Board’s electrical industry rules.

Oklahoma licenses electrical apprentices, journeymen, and contractors rather than using a statewide credential formally titled Master Electrician. The electrical contractor license is the highest-ranking category, and the Unlimited Electrical Contractor classification provides the broadest scope.

An Unlimited Electrical Contractor must document 12,000 hours of qualifying electrical construction experience, including 4,000 hours as a licensed Unlimited Electrical Journeyman and at least 6,000 hours of commercial or industrial experience while employed by a licensed electrical contractor.

Every electrical contractor must be an owner, partner, or officer in the electrical firm. The contractor is responsible for supervising and controlling the firm’s electrical contracting operations in accordance with Oklahoma law and Board regulations.

Oklahoma also offers Residential Electrical Contractor and Limited Electrical Contractor classifications. Residential contractors are restricted to the residential scope established by Oklahoma rules, while Limited Electrical Contractors qualify through a separate experience or electrical-engineering pathway and are subject to limitations associated with that classification.

The 2023 National Electrical Code was adopted in Oklahoma as the statewide minimum electrical code, subject to Oklahoma amendments. Current electrical licensing examination questions involving the NEC are based on the 2023 edition.

Oklahoma electrical contractor and journeyman licensees are subject to continuing-education requirements. Current requirements provide for 12 hours of continuing education during the applicable three-year continuing-education period, including code and revision education adopted by the Oklahoma Uniform Building Code Commission.

Passing the electrical contractor examination is one part of the licensing process. Applicants must also meet the applicable experience, application, business, insurance, and other regulatory requirements before performing work under an active Oklahoma contractor license.
