Arizona electrician licensing — what you need to know

Arizona licensing authority

Arizona licenses electrical contractors through the Registrar of Contractors (ROC). The trade exam is paired with a separate business management and law exam — both are required.

Authority: Arizona Registrar of Contractors (ROC)
Official site: https://roc.az.gov/

License types issued

Arizona issues the following electrician license classifications:

• C-11 Electrical (Commercial)
• CR-11 Electrical (Residential)
• L-11 Electrical (Limited)

Hour requirement

Arizona requires 4 years of qualifying experience for most electrical contractor classifications, plus passing the trade exam and a business management 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 Arizona Registrar of Contractors (ROC) before submitting an application — requirements occasionally change.

Code edition

Arizona adopts NEC with state amendments. Verify the current adopted edition with the Registrar of Contractors.

What candidates should know about prep

• Arizona's heat-related ampacity adjustments and outdoor service equipment requirements appear more frequently than in cooler-climate states.
• PV and solar code knowledge is weighted higher than the national average due to Arizona's solar market.
• Both the trade exam AND the business management exam must be passed for licensure.
