How to Get a California C-10 Electrical License

Careers For Electricians

Published on September 8, 2026 by Staff Writer

To qualify for a California C-10 electrical license, you must document your qualifying experience with the Contractors State License Board (CSLB). You must also pass the Law and Business exam and the C-10 Electrical Trade exam.

Required Electrical Experience

To qualify for a C-10 electrical license in California, you need at least four years of qualifying experience, which may include approved education or training credit. You must gain the required work experience within the last 10 years. Journey-level experience means you can perform electrical work without supervision.

You can gain this experience through various pathways. Working at journey level qualifies, and completing an accredited apprenticeship program may count toward the requirement. However, at least one year must be practical experience, not just education or training.

A qualified individual must verify your experience. This could be a licensed contractor, foreman, or supervisor who has firsthand knowledge of your work history. Proper documentation is crucial, as it supports your application.

Education can also play a role. For instance, a four-year electrical engineering degree may count for up to three years of the required experience, subject to CSLB evaluation. This can help if you have formal education but lack extensive fieldwork.

Incomplete or inaccurate records can delay or jeopardize your application. Following the CSLB guidelines closely can help you avoid these pitfalls.

Contractor Bonds and Insurance

To obtain an active C-10 electrical license in California, you must file a $25,000 contractor license bond with CSLB. This bond protects consumers against losses from defective construction or other license law violations.

You may also need a separate $25,000 Bond of Qualifying Individual, depending on who qualifies your license. Review CSLB’s bond requirements before completing the final licensing steps.

You must also provide proof of workers’ compensation insurance if you have employees. If you do not have employees, you may file an exemption, unless a responsible managing employee qualifies your license. The broader workers’ compensation insurance mandate is scheduled to take effect Jan. 1, 2028. Additionally, general liability insurance is highly recommended, as many project owners require it.

Maintaining your required bonds and insurance is essential for keeping your C-10 license active. Review your policies regularly to ensure they meet state requirements. Failure to maintain them can lead to license suspension.

Pro-Tip: Proving your work experience can be challenging. If you have limited direct experience, CSLB may allow education or relevant military training to count toward the requirement. However, these credits have strict limits, and you still need at least one year of practical experience.

Review CSLB’s acceptable supporting experience documentation and military application guidance before applying. When choosing certifiers, pick people who directly supervised or observed your work. They must have firsthand knowledge of your duties and time spent. Avoid using friends or coworkers who cannot verify your experience.

Make sure your certifiers are ready to answer questions from CSLB. Prepare all documents and contact information in advance to avoid delays.

Fingerprinting and Background Checks

CSLB requires fingerprinting and a background check before issuing your C-10 electrical license. It checks your criminal history through the California Department of Justice (DOJ) and the Federal Bureau of Investigation (FBI). CSLB evaluates convictions individually; a conviction does not automatically prevent licensure.

After CSLB accepts your application, it sends instructions for submitting fingerprints through Live Scan, a digital fingerprinting method. Follow the CSLB fingerprinting FAQ and use an authorized Live Scan location.

Application and Licensing Steps

To successfully obtain your C-10 electrical license, follow these key steps:

• Submit the Application for Original Contractor License with your work experience certification and the $450 application fee. Follow CSLB’s licensing steps when preparing your application.
• Provide any supporting experience documentation CSLB requests. Your application must establish four years of qualifying experience, including any approved education or training credit.
• Complete fingerprinting after CSLB accepts your application and sends instructions. Submit your fingerprints through Live Scan and return the required form copy within the deadline.
• Prepare for the Law and Business exam. Study topics like business management, labor laws, and safety regulations.
• Study for the C-10 Electrical Trade exam. Review wiring methods and the other exam areas outlined in CSLB’s study guide, using its recommended California Electrical Code and safety references.
• Schedule and pass both exams after CSLB approves your application for testing. You have 18 months from the date CSLB accepts your application to pass the required exams.
• Follow CSLB’s bond and fee letter to complete the issuance requirements. File your $25,000 contractor license bond and any additional required bond, provide proof of insurance or an applicable exemption, pay the initial licensing fee, and complete the asbestos open-book exam.

Exam Content and Preparation

To obtain a C-10 electrical license, you must pass the Law and Business exam and the C-10 Electrical Trade exam. Each exam tests different knowledge areas essential to running an electrical contracting business.

The Law and Business exam tests your understanding of the legal aspects of running an electrical contracting business.

The C-10 Electrical Trade exam covers five areas: planning and estimating; rough wiring; finish wiring and trim; startup, troubleshooting, and maintenance; and safety. The CSLB study guide lists the 2025 California Electrical Code and Cal/OSHA Title 8 safety orders among its recommended resources. For exam preparation, use these California references rather than relying solely on the National Electrical Code. You must demonstrate your understanding of safety protocols and electrical calculations.

CSLB’s examinations FAQ explains that you receive a report showing whether you passed or failed. A passing report does not show your overall score.

Preparation is crucial for success in these exams. You may benefit from study guides and practice tests. Joining a study group or taking a preparatory course can also enhance your understanding.

Avoid underestimating the exams’ difficulty. Allocate sufficient study time and review all relevant materials, using CSLB’s exam outlines to guide your preparation.

After passing both exams, follow CSLB’s bond and fee letter to complete the final licensing steps. Passing the exams alone does not authorize you to contract for electrical work.
