How to Become a Certified Electrician in California: DIR Certification and the C-10 License
By BRIX Editorial Team · Updated
California has two separate credentials. Electricians who work for a C-10 electrical contractor must be certified by the Department of Industrial Relations (DIR): a General Electrician needs 8,000 hours and a Residential Electrician 4,800, plus a $175 exam. Running your own electrical business takes a C-10 contractor license from the Contractors State License Board (CSLB).
Key takeaways
- Worker certification (DIR) and the contractor license (CSLB) are different agencies, different exams and different renewals.
- DIR categories: General Electrician 8,000 hours, Residential 4,800, Voice Data Video and Fire/Life Safety 4,000, Non-Residential Lighting 2,000.
- Until you have the hours, register as a trainee by enrolling in a state-approved school; trainee cards renew yearly at no fee.
- Certification renews every 3 years with 32 hours of CE, 2,000 hours of work and a $100 fee.
- C-10 contractor: 4 years of journey-level experience, law and business plus trade exams at PSI, a $450 application and a $25,000 bond.
Who licenses electricians in California?
Two state agencies split the job. The Department of Industrial Relations certifies individual electricians: DIR says certification is required for "Electricians who work for a contractor with a class C-10 license" (DIR). The Contractors State License Board licenses the business: a C-10 Electrical contractor license is what lets you bid and contract electrical work. A sole owner who holds the C-10 in their own name, and the qualifying person on a C-10 license, don't need DIR certification (DIR FAQ).
What are the California electrician certification categories?
Five, each with its own hour requirement under Title 8 §291.1. Hours must be worked for a C-10 contractor (lighting excepted), and each category caps how many hours a single kind of work can count. For General Electrician, for example, residential wiring can count for at most 3,000 of the 8,000 hours and stock room work for 300 (8 CCR §291.1).
| Certification | Hours required | Exam | Exam fee | Renewal | Continuing education |

| General Electrician | 8,000 hours for a C-10 contractor, in two or more work areas (8 CCR §291.1) | Yes, 70% to pass (DIR FAQ) | $175 ($100 exam + $75 admin) (DIR FAQ) | Every 3 years, $100 (DIR FAQ) | 32 hours + 2,000 work hours in 3 years (DIR FAQ) |
| Residential Electrician | 4,800 hours for a C-10 contractor (8 CCR §291.1) | Yes, 70% to pass (DIR FAQ) | $175 (DIR FAQ) | Every 3 years, $100 (DIR FAQ) | 32 hours + 2,000 work hours (DIR FAQ) |

| Non-Residential Lighting Technician | 2,000 hours installing and maintaining nonresidential lighting (8 CCR §291.1) | Yes (DIR FAQ) | $175 (DIR FAQ) | Every 3 years (DIR FAQ) | 32 hours (DIR FAQ) |
How do you become a certified electrician in California, step by step?
- 1
Register as an electrician trainee
If you don't have the hours to test, you can still work for a C-10 contractor as a registered trainee, but you must show enrollment in a state-approved school. Trainee cards renew every year with no renewal fee; re-registering after a withdrawal costs $25 (DIR FAQ).
- 2
Log hours in the right work areas
Hours count only within each category's caps. For General Electrician, commercial and industrial wiring can each count up to 6,000 hours, so a mix of jobs gets you there faster than years of nothing but residential rough-in (8 CCR §291.1).
- 3
Apply and pay $175
The fee is $100 for the exam plus $75 for administration, non-refundable (DIR FAQ). An electrician's license from another state makes you eligible to sit for the test, though it doesn't waive it.
- 4
Pass with 70% or better
"A minimum score of 70% is required to pass the test." If you don't pass, wait 60 days and pay $100 to retest (DIR FAQ). Apprentices also need graduation confirmed before their card is released.
- 5
Renew every three years
Certification lasts three years. Renewal needs 32 hours of CE from an approved provider, 2,000 hours of industry work in the past three years and a $100 fee. You can apply up to a year early (DIR FAQ).
How do you get a C-10 electrical contractor license?
Through CSLB, once you have at least four years of journey-level experience in the past 10 years (CSLB). Technical training can earn up to three years of credit, but at least one year must be practical experience (CSLB). You then pass two exams at PSI: California Law and Business, and the C-10 trade exam. Each exam allows 3½ hours, you have 18 months from application acceptance to pass, and a failed exam can be retaken after 21 days (CSLB exam FAQ).
The C-10 trade exam is closed book. The study guide for exams on or after June 1, 2024 weights it as Planning and Estimating 28%, Rough Wiring 27%, Startup, Troubleshooting and Maintenance 16% and Safety 18%, with solar and battery storage worked into each section (C-10 study guide).
| Item | Amount |
|---|---|
| Original application (one classification) | $450 (CSLB fees) |
| Initial license, sole owner / other entities | $200 / $350, covers two years (CSLB) |
| Active renewal, C-10 sole owner / other entities | $470 / $720, every two years (CSLB fees) |
| Contractor bond | $25,000 (CSLB) |
| Bond of qualifying individual (if an RME or RMO qualifies the license) | $25,000 (CSLB) |
Can you transfer an electrician license to California?
Not as a worker. DIR treats an out-of-state electrician's license as eligibility to take the California exam, not as a waiver (DIR FAQ). For contractors, CSLB says you "can't use a contractor's license from another state or country to work in California," though it "may help you get a license here" (CSLB).
Starting your own electrical business in California
- Bond and fees: budget the $450 application, the $200–$350 initial license and the $25,000 contractor bond before you can take a contract (CSLB).
- Your crew: every electrician you hire who makes connections for your C-10 company needs DIR certification or a trainee card.
- Taxes: California sales and use tax rules for contractors, and how your entity files, are in California contractor taxes and licensing.
- Business setup: entity, pricing and your first customers are in how to start an electrical business.
- General contracting: if you'll also take on remodels, see California contractor license requirements.
