Ohio electrician licensing — what you need to know

Ohio licensing authority

Ohio licenses Electrical Contractors at the state level through the Construction Industry Licensing Board (OCILB). Local jurisdictions may have additional requirements.

License types issued

Ohio issues the following electrician license classifications:

• Electrical Contractor (statewide)
• Apprentice Electrician (separate registration)

Hour requirement

Ohio Electrical Contractor license requires 5 years of experience as a master, supervisor, or registered electrical contractor in the field, plus passing the OCILB exam.

Hour requirements typically combine on-the-job experience under a licensed electrician with classroom or related supplemental instruction. Confirm exact totals and qualifying-experience rules with the Ohio Construction Industry Licensing Board (OCILB) before submitting an application — requirements occasionally change.

Code edition

Ohio adopts NEC at the state level. Verify the current adopted edition with OCILB before scheduling.

What candidates should know about prep

• OCILB exams emphasize commercial and industrial electrical methods more than residential.
• Ohio has reciprocity with several neighboring states for electrical contractor licenses.
• Apprentice electrician registration is separate from the contractor exam.
