1. What is the C-10 License?
In California, you cannot just call yourself an electrician.
• Certified Electrician: A worker who holds a state certification card (Blue Card).
• C-10 Contractor: A business owner licensed to bid on jobs and hire employees. This guide focuses on becoming the Contractor (The Boss).
2. Step-by-Step: How to Get Licensed
Step 1: Prove Your Experience
The CSLB requires proof of 4 years of experience in the last 10 years. This must be verified by a qualified person (another C-10 contractor, union rep, or foreman).
Tip: Military service or technical college degrees can count for up to 3 years of credit.
Step 2: Pass the Two CSLB Exams
You must schedule and pass two exams at a PSI testing center:
- Law & Business: Covers contracts, safety (Cal/OSHA), and labor laws.
- C-10 Trade Exam: Covers NEC Code, load calculations, solar PV systems, and low voltage logic.
Step 3: Bond & Insurance
California mandates a $25,000 Contractor Bond. This is non-negotiable. If you hire workers, you also need Workers' Compensation Insurance.
