1. Confirm the Limited Electrical Contractor category. Review the license qualifications and determine whether this contractor category matches your experience and intended role within an Oklahoma electrical firm.
2. Meet the ownership or officer requirement. A Limited Electrical Contractor must be an owner, partner, or officer in the electrical firm.
3. Document qualifying experience. Applicants must demonstrate the substantial electrical experience required for Limited Electrical Contractor licensing.
4. Submit the electrical contractor application. Provide the Oklahoma Construction Industries Board with the required application and supporting documentation.
5. Receive examination authorization. The Construction Industries Board reviews the application and determines whether the candidate qualifies to proceed with testing.
6. Schedule testing through PSI. Approved candidates arrange their required examinations through the testing provider.
7. Prepare for the Limited Electrical Contractor examination. Study electrical theory, the 2023 NEC, installation requirements, OSHA safety material, calculations, conductors, raceways, grounding, services, and other technical subjects.
8. Prepare for Electrical Business and Law. Review Oklahoma licensing regulations, estimating, project management, contracts, finances, labor, risk management, payroll, insurance, bonds, liens, and workers’ compensation.
9. Complete the required examinations. Pass the applicable examinations required for Oklahoma electrical contractor licensure.
10. Complete active contractor requirements. Provide applicable bond, insurance, workers’ compensation, and other required documentation before engaging in electrical contracting under an active license.

State Requirements

All Oklahoma Electrical Contractors must be an owner, partner, or officer in the electrical firm. Limited Electrical Contractors have additional qualification requirements because this license category is structured differently from the residential and unlimited contractor pathways.

One qualifying Limited Electrical Contractor pathway requires a degree in Electrical Engineering from an accredited college or university together with 8,000 hours of electrical experience involving field construction, electrical estimating, or electrical project management in commercial or industrial electrical work.

An alternative pathway requires verification of 16,000 hours of experience in the electrical trade performing electrical work, estimating, or project management in commercial or industrial work.

Limited Electrical Contractors are prohibited from engaging in the work of an apprentice or journeyman electrician. The contractor role focuses on the responsibilities associated with the electrical firm and the contractor-level license.

After successfully completing the required examinations, the contractor license remains inactive until the Oklahoma Construction Industries Board receives the documentation required to activate it. Active electrical contractors are required to maintain a $5,000 corporate surety bond payable to the Oklahoma Construction Industries Board and provide evidence of at least $50,000 in commercial general liability insurance.

Electrical contractors must also maintain applicable workers’ compensation coverage, an authorized exemption, or qualifying self-insurance as required by Oklahoma law. Maintaining current insurance and other active-contractor requirements is important because a contractor may not legally contract for covered services with an inactive license.
