The California General Electrician Guide

What Is California General Electrician Certification?

A General Electrician in California is an individual who works for an electrical contractor installing, constructing, or maintaining electrical systems covered by the National Electrical Code. The credential is issued by the California Department of Industrial Relations (DIR), Division of Labor Standards Enforcement (DLSE), Electrician Certification Unit. It is the certification that takes you off trainee status and lets you perform covered electrical work without the supervision requirements attached to an Electrician Trainee card.

California has no journeyman license in the sense used by Texas or Colorado. The worker-level credential is General Electrician certification, and most electricians and employers simply call it the journeyman credential. A separate credential — the C-10 electrical contractor license from the Contractors State License Board (CSLB) — belongs to the business that bids and pulls permits. If you work with the tools for a C-10 contractor, General Electrician certification is your path.

Exam administration changed in 2026: for exams on or after June 1, 2026, the program is administered by CPS HR Consulting and delivered at Pearson VUE test centers. PSI ran the program through May 2026. DIR/DLSE still decides eligibility; CPS HR handles scheduling and Pearson VUE delivers the exam.

The Requirements

• 8,000 hours of on-the-job electrical work for a C-10 licensed electrical contractor, on systems covered by the NEC. The hours must span two or more of nine defined categories, and each category caps how much counts.
• Category caps: commercial wiring up to 6,000 hours; industrial wiring up to 6,000; residential wiring up to 3,000; voice/data/video installation up to 1,500; troubleshooting and maintenance up to 1,500; underground conduit installation up to 750; finish work and fixtures up to 600; fire/life-safety and nurse call up to 600; stock room and material handling up to 300.
• Alternative routes to eligibility: a completion certificate from a state-approved apprenticeship program; an electrician license from another state (you still take the California exam); being in your final year of an approved apprenticeship with a DAS-1 form; or completing an approved electrician trainee curriculum.
• Approved application: DLSE reviews your experience documentation and notifies you when you are approved to test — you generally have one year from the eligibility notice to take the exam.

The five classifications with exams are: General Electrician, Residential Electrician, Fire/Life Safety Technician, Voice Data Video Technician, and Non-Residential Lighting Technician. This guide covers the General Electrician exam, the broadest classification.

Exam Format: On-Screen References, Pearson VUE

The General Electrician exam is computer based with 100 multiple-choice questions, 4 hours and 30 minutes allowed, and 70% required to pass. The references are provided electronically inside the testing system: the exam question appears on the right of your screen and the reference PDFs open on the left, with zoom and Ctrl+F search.

You may not bring your own NEC, notes, or calculator — no tabbed code book, no personal references. An on-screen calculator is provided. Candidates who trained in open-book states find this the biggest adjustment: the skill to practice is searching the electronic PDFs by keyword (Ctrl+F) rather than flipping to a tab. Up to 10 unscored experimental questions may be included without affecting your time or score.

What the Exam Covers

The official Candidate Information Bulletin (July 2026, CPS HR / Pearson VUE) weights the 100 questions across four broad domains:

• Installation — about 66 questions (66%). Wiring methods, boxes, conduit and conductor sizing, service sizing, grounding and bonding, overcurrent devices, motors, lighting, HVAC/refrigeration, low-voltage systems, devices, communications, fire systems, clearances, and terminations.
• Determination of Electrical System Requirements — about 22 questions (22%). Electrical theory, symbols and diagrams, feeder and branch-circuit sizing, motor sizing, circuit protection, and grounding/bonding design.
• Safety — about 6 questions (6%). NFPA 70E safe work practices, personal protective equipment, and Cal/OSHA construction safety.
• Maintenance and Repair — about 6 questions (6%). Testing equipment, troubleshooting, and repair of devices, branch circuits, and overcurrent devices.

The exam may also contain questions based on trade knowledge or general industry practices. Because two-thirds of the exam is installation work, budget your study time in that proportion — box, conduit, and conductor sizing; wiring methods; and grounding/bonding dominate.

How to Prepare

• Understand the reference format first. The NEC 2023, NFPA 70E, and Cal/OSHA Pocket Guide are on-screen PDFs. Practice finding sections by keyword search, not by tabs. This is the single biggest difference from other states.
• Know the chapter map of the NEC 2023. Chapter 2 wiring and protection, Chapter 3 wiring methods, Chapter 4 equipment, Chapter 5 special occupancies, Chapter 6 special equipment, Chapter 7 special conditions, Chapter 8 communications, Chapter 9 tables.
• Drill the sizing math with the code open. Conductor ampacity (Table 310.16), box fill (314.16), conduit fill (Chapter 9), service and feeder sizing (Article 230/215), and grounding/bonding (Article 250).
• Add NFPA 70E and Cal/OSHA to your routine. Arc flash boundaries, PPE categories, approach boundaries, lockout/tagout, GFCI protection on construction sites, and Cal/OSHA pocket-guide rules — most prep courses skip these, but they are on the exam.
• Simulate under exam conditions. Full-length timed runs of 100 questions in 4h30, answering with references open, build the pacing and search discipline the real exam rewards.

Retaking the Exam

If you fail, you must wait 60 days from your exam date before submitting a retest application, and you pay the exam fee again (about $100). Your one-year eligibility window keeps running during the wait. Exam payments are not refundable or transferable — missed appointments are voided with no refund.

After Certification: Renewal and the C-10 Path

Certification renews every 3 years and requires 32 hours of continuing education from a California-approved provider. You can apply for renewal up to one year before expiration. If you want to run your own electrical business, the next step is the C-10 electrical contractor license through the CSLB — a separate exam and application that lets you bid work, pull permits, and hire certified electricians.
