Overview
California operates one of the most detailed electrical apprentice licensing programs in the United States, administered by the Division of Apprenticeship Standards (DAS) under the Department of Industrial Relations (DIR). To become a licensed Inside Wireman (Journeyman Electrician) in California, you must complete 8,000 hours of on-the-job training across nine distinct work categories. There is no separate classroom hour requirement for the Inside Wireman certification at the state level, though most JATC programs include related technical instruction as part of their curriculum.
What makes California unique is the granularity of its hour tracking system. Rather than logging generic "electrical work" hours as many states allow, California requires apprentices to document time spent in nine specific categories, each with its own credit cap. This means you cannot complete all 8,000 hours doing only commercial wiring, for instance. The state explicitly requires experience across at least two categories, and individual categories are capped at well below the total requirement. This structure is designed to ensure that every licensed journeyman electrician in California has well-rounded, hands-on experience across different facets of the electrical trade.
The Division of Apprenticeship Standards also enforces that apprentices work under the direct supervision of a qualified journeyman electrician at a ratio set by the specific apprenticeship program. Most programs maintain a ratio of one apprentice per journeyman, though some allow up to two apprentices per journeyman depending on the type of work and the apprentice's experience level. Your supervising journeyman is responsible for verifying your hours, and their signature on your documentation is a legal attestation of the work you performed.
Hour Categories & Requirements
California requires 8,000 hours across 9 categories.
Commercial Wiring
Installation, alteration, and maintenance of electrical systems in commercial buildings including offices, retail spaces, restaurants, and public facilities. Covers conduit bending, wire pulling, panel installation, and device termination.
Industrial Wiring
Work on electrical systems in manufacturing plants, warehouses, and industrial facilities. Includes motor controls, three-phase power distribution, programmable logic controllers (PLCs), and heavy equipment connections.
Residential Wiring
Electrical work in single-family homes, apartments, and condominiums. Encompasses service entrance installations, branch circuit wiring, lighting fixtures, outlets, and residential panel upgrades.
Troubleshooting
Diagnosing and repairing electrical system faults using testing equipment, schematics, and systematic troubleshooting methods. Applies across commercial, industrial, and residential settings.
Voice-Data-Video (VDV)
Installation and termination of low-voltage systems including network cabling (Cat5e/Cat6), fiber optics, telephone systems, security cameras, and audio/video distribution.
Underground Systems
Trenching, conduit installation, and wire pulling for underground electrical distribution. Includes duct banks, manholes, hand holes, and direct-burial cable installations.
Finish Work
Final connections and trim-out of electrical devices including switches, receptacles, light fixtures, cover plates, and breaker labeling. Typically the last phase of electrical construction.
Fire/Life Safety
Installation and wiring of fire alarm systems, emergency lighting, exit signs, and life safety circuits. Requires understanding of NFPA 72 and local fire codes.
Stock Room/Material Handling
Organizing, inventorying, and distributing electrical materials and tools. Includes reading material lists, loading job trailers, and managing tool cribs. Strictly capped at 300 hours.
Application Process
- 1
Complete all 8,000 hours of on-the-job training across the required categories through a state-approved apprenticeship program or an approved employer.
- 2
Obtain and complete DIR Form DAS-7050 (Certification of Completion of Apprenticeship). This form must be filled out on paper — California does not accept electronic submissions for apprenticeship certifications.
- 3
Have your supervising journeyman electrician(s) sign and date the verification sections of the form. Each period of work must be verified separately.
- 4
Have your apprenticeship program sponsor (JATC or employer) sign the form certifying your completion.
- 5
Submit the completed DAS-7050 to the Division of Apprenticeship Standards along with any required supporting documentation.
- 6
Once your apprenticeship completion is certified, you are eligible to take the state journeyman electrician certification exam administered by the California Department of Industrial Relations.
- 7
After passing the exam, apply for your C-10 Electrical Contractor License through the Contractors State License Board (CSLB) if you wish to operate independently, or work as a certified journeyman under a licensed contractor.
Important Rules & Gotchas
Paper-only submissions: California DIR does not accept any electronic forms or digital signatures for apprenticeship certifications. Plan ahead and have physical forms ready for supervisor signatures.
Two-category minimum: You must have documented hours in at least two different categories. An application with all hours in a single category will be rejected regardless of the total.
Credit caps are strict: Once you hit a category cap (e.g., 6,000 hours in Commercial), additional hours in that category do not count toward your 8,000-hour total. Track your distribution carefully.
Stock Room hours are severely limited: Only 300 hours of stock room/material handling work count. Apprentices are sometimes assigned to the stock room for extended periods — those hours beyond 300 are wasted from a licensing perspective.
Supervisor ratio enforcement: If you are found to have worked without proper supervision (correct journeyman-to-apprentice ratio), those hours may be disqualified during audit.
No retroactive credit: Hours worked before registering as an apprentice with the DAS generally cannot be counted. Register first, then start logging.
Form errors cause delays: Corrections, white-out, or mismatched dates on the DAS-7050 will result in the form being returned. Use a fresh form if you make a mistake.
Classroom & Education Requirements
California does not impose a standalone state classroom hour requirement for Inside Wireman certification. However, most Joint Apprenticeship and Training Committee (JATC) programs affiliated with IBEW or independent electrical contractor associations include substantial classroom instruction as part of their curriculum — typically 800 to 1,000 hours over the course of a 5-year apprenticeship.
If you are not enrolled in a JATC program and are instead completing your apprenticeship through an employer-sponsored program, classroom hours may still be required by the program itself even though they are not separately tracked by the state for licensing purposes.
Regardless of classroom requirements, all apprentices benefit from studying the National Electrical Code (NEC), electrical theory, blueprint reading, and safety practices. The state certification exam is based on the current NEC, so classroom instruction or self-study is effectively necessary to pass even though it is not a formal state requirement.
License Renewal & Continuing Education
California journeyman electrician certifications must be renewed every three years (triennial). The current renewal fee is approximately $100.
You must complete 32 hours of approved continuing education (CE) during each three-year renewal cycle. CE courses must be from a provider approved by the Department of Industrial Relations.
At least 16 of the 32 CE hours must cover the National Electrical Code (NEC) changes applicable to the current code cycle. The remaining hours may cover safety, energy efficiency, renewable energy systems, or other approved topics.
Failure to renew on time results in an inactive license. You may not perform electrical work with an inactive certification. Reinstatement requires completing all outstanding CE hours plus any applicable late fees.
Tips for Tracking Your Hours
Start logging from day one. Even hours that feel routine (pulling wire, bending conduit) count toward specific categories. Get in the habit of recording every workday.
Categorize as you go. Do not wait until the end of the month to sort hours into categories. Memory fades quickly, and miscategorized hours can create cap problems later.
Track supervisor information alongside hours. Record which journeyman supervised you each day — you will need their signature on your final forms.
Monitor category caps proactively. If you are approaching 6,000 hours in Commercial, speak with your foreman about getting assigned to different types of work. Running into a cap with thousands of hours remaining is one of the most common delays apprentices face.
Keep backup records. Paper forms can be lost, damaged, or have ink fade. Maintain a digital backup of your daily hour logs. WireHours automatically tracks your categories and warns you as you approach credit caps.
Plan for the two-category minimum early. Even if your shop does mostly commercial work, seek out opportunities in residential, industrial, or troubleshooting. A well-rounded apprentice is a more employable journeyman.
Frequently Asked Questions
How many hours do I need to become a licensed electrician in California?
You need 8,000 hours of on-the-job training spread across at least 2 of California's 9 hour categories. Each category has its own credit cap, so you cannot complete all hours in a single category.
Can I submit my California apprenticeship hours online?
No. California DIR requires all apprenticeship certification forms (DAS-7050) to be submitted on paper with original wet signatures. Electronic or digital submissions are not accepted.
What happens if I exceed the credit cap in one category?
Hours logged beyond a category's cap do not count toward your 8,000-hour total. For example, if you have 6,500 hours of commercial work, only 6,000 count. You would still need 2,000 hours from other categories.
Do I need classroom hours for a California electrician license?
California does not have a separate state-mandated classroom hour requirement for Inside Wireman certification. However, most apprenticeship programs include classroom instruction, and studying the NEC is essential for passing the certification exam.
