California Journeyman Electrician Exam Prep

California replaced the traditional journeyman license model with a statewide certification program run by the Electrician Certification Unit (ECU) of the Division of Labor Standards Enforcement. The General Electrician certification requires 8,000 hours of work for an electrical contractor installing, constructing, or maintaining systems covered by the NEC. There are no municipal journeyman electrician licenses in California.

The exam is administered by PSI Services LLC and draws on the electrical code adopted in California: the 2025 California Electrical Code (Title 24, Part 3), based on the 2023 NEC, effective January 1, 2026. Commonly tested areas include branch circuits and feeders, wiring methods, grounding and bonding, overcurrent protection, and load calculations.

Journeyman-level electricians in California hold one of the DIR certifications, depending on the scope of work:

• General Electrician - All electrical work for a C-10 contractor; requires 8,000 hours of qualifying experience.
• Residential Electrician - Residential work only; requires 4,800 on-the-job training hours.

The General Electrician certification exam is delivered by PSI Services LLC at PSI test centers. It has 100 questions and a 4 hour 30 minute time limit, and results are available immediately. You must take the exam within 1 year of receiving your eligibility notice. New scheduling procedures apply to exams taken on or after June 1, 2026; check the ECU site before booking.

The passing score for the California General Electrician certification exam is 70 percent. If you fail, you can retake the exam after a 60-day waiting period for a $100 retest fee. Confirm the current passing standard with the ECU before your exam date.

Requirements to sit for the California General Electrician certification exam include:

• 8,000 hours of work for an electrical contractor installing, constructing, or maintaining systems covered by the NEC.
• A completed application submitted to the Electrician Certification Unit (ECU).
• Payment of the application fee, which includes your first exam attempt.

Requirements can change. Always confirm current certification rules with the official state licensing authority before applying.

The application fee is $175 including one exam, $275 including two exams, or $375 including three exams. Retesting costs $100 after a 60-day wait. Renewal costs $100 every 3 years, and an expired renewal costs $200 including an exam retake. Always confirm current fee amounts with the ECU before submitting payment.

A 4 to 6 week study plan tailored to the NEC works well for most candidates:

• Week 1: Review code layout, definitions (Article 100), and wiring methods (Articles 300-399).
• Week 2: Study grounding and bonding (Article 250) in depth.
• Week 3: Work through load calculation problems using Article 220.
• Week 4: Take practice tests, review missed questions, and build speed for the 100-question, 4 hour 30 minute format.
