Exam Details

The Oklahoma Residential Electrical Contractor trade examination consists of 80 scored items. Candidates receive 210 minutes to complete the examination, and a score of 70% correct is required to pass.

The examination is administered through PSI for the Oklahoma Construction Industries Board. Eligibility to take the examination is determined by the Construction Industries Board. After an applicant has been approved, the candidate can proceed with scheduling the appropriate examination through PSI.

The Residential Electrical Contractor examination covers a broad range of electrical knowledge. The official content outline includes general knowledge such as permits, inspections, preservation of structural integrity, needs analysis, and estimating. Candidates are also tested on electrical fundamentals including voltage, current, resistance, series and parallel circuits, power, AC theory, troubleshooting, testing, and use of the National Electrical Code.

Other major areas include electrical installation requirements; services, feeders, and branch circuits; overcurrent protection; grounding and bonding; conductor and cable selection; raceways and boxes; special occupancies and equipment; low-voltage and signaling systems; communications; lighting and signs; and construction safety.

The scope also reaches practical residential applications such as service installations, voltage drop, branch circuits, air-conditioning equipment, grounding electrode conductors, equipment grounding conductors, underground wiring, nonmetallic-sheathed cable, service-entrance cable, conduit, box fill, swimming pools, fountains, hot tubs, communications circuits, photovoltaic systems, fire alarms, emergency systems, and lighting installations.

Open Book Test

The Oklahoma Residential Electrical Contractor examination is an open book test. Candidates may bring approved reference materials into the examination center, making familiarity with the books an important part of exam preparation.

The approved reference list includes the 2023 National Electrical Code as revised and adopted by the Oklahoma Uniform Building Code Commission, Code of Federal Regulations 29 CFR Part 1926 with applicable amendments, and Ugly's Electrical References. For code questions, candidates are tested using the specific code edition listed for the examination.

Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used for indexing. Temporary tabs such as Post-It notes are not permitted. Candidates may not write in their references during the examination, and additional loose papers may not be placed inside approved references.

The testing rules also specifically state that NEC Handbooks and spiral-bound copies of the National Electrical Code are not allowed in the test center. Candidates should prepare their references in accordance with PSI's current examination-center rules before test day.

An open-book exam still requires careful preparation. With 80 scored questions and 210 minutes, candidates need to balance knowledge of the electrical trade with efficient reference navigation. Spending too much time searching for individual answers can make time management difficult. Learning the structure of the NEC, establishing a consistent indexing system, and practicing where to locate commonly tested provisions can make study sessions more productive.

Licensing Steps

Oklahoma electrical licensing is administered by the Oklahoma Construction Industries Board. A candidate pursuing the Residential Electrical Contractor classification begins by meeting the state's qualification requirements and submitting the required electrical license application to the Board.

The Construction Industries Board reviews the application and determines eligibility for examination. Once approved, the applicant's information is forwarded for testing, and the candidate can schedule the required examinations through PSI.

Applicants for an Oklahoma electrical contractor license are required to pass the applicable trade examination and the electrical Business and Law portion unless an applicable licensing provision provides otherwise. The Residential Electrical Contractor book package on this page is focused on the references for the Residential Electrical Contractor trade examination.

After completing the required examinations, applicants must satisfy the remaining Construction Industries Board requirements associated with issuance and activation of the contractor license. Contractors must also maintain the applicable licensing, insurance, and compliance requirements established by Oklahoma law and Construction Industries Board rules.

State Requirements

Oklahoma defines the Residential Electrical Contractor classification around residential electrical contracting. Residential Electrical Contractors are limited to contracting for the wiring of buildings defined by the National Electrical Code for one- and two-family dwellings.

The Construction Industries Board states that Residential Electrical Contractor applicants must document 4,000 hours as a Residential or Unlimited Journeyman Electrician under the employment and supervision of an Electrical Contractor. The state also requires 3,000 hours as a registered apprentice, with up to 1,000 hours that may be satisfied by formal electrical education. Educational experience used toward the requirement must consist of actual classroom hours verified by transcript.

All electrical contractors must also be an owner, partner, or officer in the electrical firm associated with the contractor license. These requirements make the contractor classification different from an entry-level electrical credential: the applicant is expected to arrive with documented trade experience and a substantial foundation in electrical work.

The Residential Electrical Contractor examination itself evaluates knowledge that goes beyond simply recognizing code language. The scope includes the design, planning, layout, installation, repair, and alteration of electrical conductors, fixtures, appliances, apparatus, raceways, conduit, and related electrical equipment for residential applications.

Reference Books

• National Electrical Code, NEC, 2023
  NFPA 70 is the central code reference for the electrical trade examination. Candidates should become familiar with its organization and practice locating requirements for services, branch circuits, feeders, grounding and bonding, conductors, wiring methods, raceways, boxes, overcurrent protection, equipment, and special installations.
• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
  This construction safety reference supports preparation for the safety portion of the exam. Topics may involve personal protective equipment, excavations, emergency action plans, safety training, ventilation, first aid, signs and barricades, tools, ladders, scaffolds, illumination, hazardous materials, material handling, and fall protection.
• Ugly's Electrical References
  This practical reference provides quick access to electrical information useful for trade calculations and problem solving. Becoming familiar with its layout can help candidates efficiently locate formulas, tables, conversions, and electrical data while studying and during the open-book examination.

Test Information and Study Materials

A productive study approach should combine code navigation with actual problem solving. Begin by learning the major sections of the NEC rather than trying to memorize every rule. Know where subjects such as branch circuits, feeders, services, overcurrent protection, grounding and bonding, wiring methods, motors, equipment, and special occupancies are located.

Electrical calculations also deserve regular practice. The official examination outline includes voltage, current, resistance, series and parallel circuits, power, AC theory, voltage drop, conductor selection, box fill, and related technical areas. Working problems while using the approved references helps develop the same search-and-apply process needed during the examination.

Safety should be treated as a separate study area rather than an afterthought. Review 29 CFR Part 1926 with emphasis on the construction safety categories identified in the examination outline. Practice locating requirements instead of relying exclusively on memory.

Ugly's Electrical References should also become a familiar navigation tool. Know how its tables and formulas are organized and practice finding common technical information quickly. The value of a reference during an open-book examination depends heavily on how confidently the candidate can use it.

Timed practice can help bring these skills together. The examination allows 210 minutes for 80 scored questions, so study sessions should eventually include periods where candidates answer questions while locating information under a realistic time constraint. This helps develop judgment about when to solve a problem from knowledge, when to confirm an answer in a reference, and when to mark a difficult question and return to it later.
