Candidates should use the code edition required by the Oklahoma Construction Industries Board and PSI for the scheduled exam while using this combo for structured study, practice exams, final exams, flash card reinforcement, and NEC-focused preparation.

Open Book Test

The Oklahoma Unlimited Electrical Contractor examination is an open book test. Candidates are responsible for bringing their own approved references to the examination center. A silent, nonprinting, nonprogrammable calculator may be used in the examination center.

Approved 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 not bring additional papers with approved references. Any additional materials may be removed from the references and confiscated.

References may be tabbed or indexed with permanent tabs only. Temporary tabs, such as Post-it notes, are not allowed and must be removed before the exam begins. Downloaded references must be spiral bound, hole-punched and placed in a binder, or stapled in the left-hand corner according to exam rules.

Open-book testing still requires serious preparation. The exam is not simply about bringing a code book into the room. Candidates need to understand how the NEC is organized, how to identify the topic being tested, how to locate the correct Article or table quickly, and how to apply the rule accurately within the time allowed.

This combo supports open-book preparation by combining practice exams, full final exams, and flash card review. The practice exams help you recognize the subject area being tested. The final exams help you work through longer exam-style sessions. The flash cards help strengthen recall so you do not have to search for every basic concept during the test.

State Requirements

Oklahoma electrical licensing is regulated by the Oklahoma Construction Industries Board. The Board protects life and property through licensing and inspection of related trades, including electrical work. Electrical contractors must meet Board requirements before engaging in electrical contracting in the state.

All Oklahoma Electrical Contractors must be an owner, partner, or officer in the electrical firm. Electrical Contractor is the highest-ranking electrical license category in Oklahoma. The Unlimited Electrical Contractor category is unlimited in the type of electrical contracting work the licensee may perform.

For the Unlimited Electrical Contractor category, Oklahoma requires 12,000 verifiable hours of on-the-job experience in electrical construction work. The candidate must also show proof of 4,000 hours of experience as a licensed Unlimited Electrical Journeyman. Of the total experience, 6,000 hours must be in commercial industrial work obtained while employed by a licensed Electrical Contractor.

Test Information and Study Materials

Oklahoma Unlimited Electrical Contractor exam preparation should include NEC review, electrical calculations, OSHA safety study, reference navigation, and Oklahoma electrical regulation awareness. Candidates should study permits and inspections, needs analysis, estimating, voltage, current, resistance, power, AC theory, three-phase theory, troubleshooting, NEC definitions, temporary wiring, cranes, hoists, elevators, escalators, and approved electrical installation methods.

Services, feeders, and branch circuits are important exam areas. Candidates should study services, voltage drop, services over 600 volts, feeders, outside branch circuits and feeders, branch circuits, space-heating circuits, snow-melting circuits, pipe-heating circuits, air-conditioning equipment, and refrigeration equipment. These topics often require careful NEC navigation and strong understanding of electrical system layout.

Grounding and bonding, overcurrent protection, conductors, cables, raceways, and boxes also deserve focused preparation. Candidates should practice selecting conductors, using conduit-fill rules, applying box-fill requirements, identifying raceway types, sizing grounding electrode conductors, sizing equipment grounding conductors, and applying overcurrent protection rules.

Safety study is also part of the Oklahoma exam. Candidates should review OSHA construction safety topics, including PPE, excavation safety, emergency action plans, ventilation, first aid kits, signs, signals, barricades, tools, ladders, workplace illumination, scaffolds, toxic materials, cleanup, material safety data sheets, material handling, and fall protection.

The 12 practice exams in this combo help you build familiarity with exam-style questions over time. After each practice exam, review missed questions carefully. Missed questions show where your next study session should focus. If you miss a service question, return to service and feeder review. If you miss a grounding question, review grounding and bonding. If you miss a safety question, return to the OSHA reference area being tested.

The 2 full final exams are best used after completing a broader review of the study guide and flash cards. Treat each final exam as a readiness checkpoint. Work through the questions in a focused setting, monitor your pacing, and review the results afterward. This helps identify whether you are ready for longer testing conditions and where final review time should go.

The flash cards support active recall, which is valuable even for open-book testing. Strong recall helps you save time and avoid unnecessary searching. Flash cards can help reinforce definitions, formulas, Article topics, electrical theory concepts, calculation methods, safety terms, Oklahoma contractor terms, and exam-specific language.
