Electrician Trainee Registration
This is the registration you hold while you build hours for a C-10 electrical contractor, and it turns on enrollment in a state approved school rather than on experience.
DIR electrician trainee page
| Hours | None to register. The unit describes it as the route for a person who lacks the work experience or the related instruction needed to sit the certification exam.DIR electrician trainee page |
|---|---|
| Enrollment | An electrician trainee must be enrolled in a state approved school, and proof of enrollment goes in with the application. The DIR list carries a number, a name and an address for each approved school.DIR electrician trainee page, DIR list of approved schools |
| Exam | There isn't one at this stage. The certification exam comes after the hours and the approved curriculum are done.CCR Title 8 section 291.2(g) |
| Fees | $25, by check payable to DIR - Electrician Certification Fund. The FAQ says there is no trainee renewal fee.CCR Title 8 section 292.0, ECU FAQ |
| Term | It renews every year on current enrollment verification and an unofficial transcript.ECU FAQ |
| Supervision | A certified electrician supervises only one electrician trainee.DIR electrician trainee page |
| Filing | Paper only for now. The unit's online services page says trainee online registration will be available at a later date and asks applicants to keep mailing the form.ECU online services page |
Proof of school enrollment goes in with the form, not after it
The registration isn't a permit to go and find a school later. The state requires an electrician trainee to be enrolled in a state approved school and to send proof of enrollment with the application, and the yearly renewal asks for current enrollment verification and an unofficial transcript. Falling out of class is what usually ends a trainee registration, not falling off a payroll. If a school isn't on the DIR list, its classroom hours do not do the job.
DIR electrician trainee page
General Electrician
The broadest of the five certifications, and the card California employers mean when a job ad asks for a journeyman.
CCR Title 8 section 290.1
| Hours | 8,000 hours of work for a C-10 electrical contractor installing, constructing or maintaining electrical systems covered by the National Electrical Code, across two or more work areas.CCR Title 8 section 291.1 |
|---|---|
| Classroom | The state describes the trainee route as 8,000 hours of on the job experience plus 720 hours of related and supplemental instruction, and the application needs proof of the approved curriculum.DIR General Electrician page, CCR Title 8 section 291.2(g) |
| Exam | 100 questions, 4 hours 30 minutes, 70 percent to pass. Installation carries 66 percent of the paper and determining system requirements another 22.Candidate Information Bulletin |
| Fees | $175 for a single exam, being the $100 exam fee plus the $75 application fee. Two exams cost $275 and three cost $375, and nothing is processed without all required fees.ECU application instructions page, CCR Title 8 section 292.0 |
| Timing | The Division answers on eligibility within 30 days, and the exam has to be taken within one year of that notice.CCR Title 8 section 291.2 |
| Term | Three years, at $100, with 32 hours of further electrical education and a declaration of 2,000 hours worked in the industry.CCR Title 8 section 291.5 |
Residential wiring stops counting at 3,000 hours inside the 8,000
Somebody who has only ever wired houses cannot reach 8,000 on that alone. Section 291.1 splits the total into work areas and puts a ceiling on each one: residential wiring 3,000, commercial wiring 6,000, industrial wiring 6,000, voice data video installation 1,500, troubleshooting and maintenance 1,500, underground conduit 750, finish work 600, Fire/Life Safety and nurse call 600, stock room 300. Check your own hours against those ceilings before you file, because the application fee isn't refundable.
CCR Title 8 section 291.1
Residential Electrician
The certification for an electrician whose hours are in dwellings, at 4,800 hours instead of 8,000.
CCR Title 8 section 291.1
| Hours | 4,800 hours of work for a C-10 electrical contractor, from one or more work areas. Residential wiring is capped at the full 4,800, so house work alone can carry the total.CCR Title 8 section 291.1 |
|---|---|
| Exam | 80 questions, 3 hours 30 minutes, 70 percent to pass. Installation is 66 percent of the paper and determining system requirements another 23.Candidate Information Bulletin |
| Curriculum | Proof of completing the approved curriculum for this classification goes in with the application, and certification follows only after the exam and the proof of experience.CCR Title 8 section 291.2(g) |
| Fees | $175 for a single exam, $275 for two and $375 for three. No application is accepted for processing unless every required fee comes with it.ECU application instructions page, CCR Title 8 section 291.2 |
| Scale | It's a rare card. The statistics page dated April 12, 2023 counted 739 Residential certifications against 29,724 General ones.ECU statistics, April 12, 2023 |
| Term | Three years, at $100, with 32 hours of further electrical education and a declaration of 2,000 hours worked in the industry.CCR Title 8 section 291.5 |
The residential card doesn't follow you onto commercial or industrial work
Residential Electrician is its own classification, not a step inside the General one. If your work later moves into commercial or industrial buildings, the General Electrician certification is the one to build toward, and that means 8,000 hours across two or more work areas with residential wiring capped at 3,000. The paperwork has to line up with the work, because the application asks which certification you seek and section 291.2(g) wants the approved curriculum for that classification.
CCR Title 8 section 290.1
Fire/Life Safety Technician
The card for fire alarm and nurse call work, and the only one of the five with a way in that isn't hours.
CCR Title 8 section 291.1
| Hours | 4,000 hours on systems under National Electrical Code Article 760, worked for a C-10 electrical contractor. Installations can carry the full 4,000, with 750 for troubleshooting and maintenance, 300 for nurse call and 300 for proprietary systems training.CCR Title 8 section 291.1 |
|---|---|
| Other route | NICET Fire Alarm Systems Level II or above is accepted in place of the hours. It's the only place in the five classifications where an outside credential stands in.CCR Title 8 section 291.1 |
| Exam | 50 questions, 2 hours 15 minutes, 70 percent to pass. Fire alarm systems are 34 percent of the paper and preparation another 24.Candidate Information Bulletin |
| Books | The usual three on screen plus NFPA 72 in its 2025 edition and NFPA 170 in its 2018 edition. You may not bring or use your own reference materials.Candidate Information Bulletin |
| Fees | $175 for a single exam. Two exams are priced at $275, which is less than two single applications.ECU application instructions page |
| Term | Three years, at $100, with 32 hours of further electrical education and a declaration of 2,000 hours worked in the industry.CCR Title 8 section 291.5 |
The NEC on screen is 2023 while NFPA 72 is 2025
Two thirds of this paper sits outside the National Electrical Code, in NFPA 72 and the fire safety symbols standard, and the edition years don't match. Every candidate gets NFPA 70 in its 2023 edition, NFPA 70E 2024 and the Cal/OSHA Pocket Guide updated 2022, and this exam adds NFPA 72 2025 and NFPA 170 2018. Don't assume the fire alarm standard tracks the code year, and don't plan on your own marked up copy of either, because the books belong to the testing system.
Candidate Information Bulletin
Voice Data Video Technician
The certification for structured cabling, telecom and audiovisual work, tied to five articles of the code.
CCR Title 8 section 291.1
| Hours | 4,000 hours on systems within National Electrical Code Articles 725, 770, 800, 810 and 820, worked for a C-10 electrical contractor.CCR Title 8 section 291.1 |
|---|---|
| Caps | Installations covering wire pulling, terminations and panels can carry the whole 4,000. Troubleshooting and maintenance stop at 750, stock room work at 300 and trade specific training at 300.CCR Title 8 section 291.1 |
| Exam | 50 questions, 2 hours 15 minutes, 70 percent to pass, over the most spread out outline of the five, with preparation and installation at 22 percent each.Candidate Information Bulletin |
| Books | The usual three on screen plus the BICSI Information Technology Systems Installation Methods Manual, 6th Edition.Candidate Information Bulletin |
| Fees | $175 for a single exam, $275 for two and $375 for three, payable to the DIR Electrician Certification Fund.ECU application instructions page |
| Term | Three years, at $100, with 32 hours of further electrical education and a declaration of 2,000 hours worked in the industry.CCR Title 8 section 291.5 |
A General card doesn't cover this work, and this card doesn't cover general work
Each of the five classifications stands on its own. Voice data video installation counts toward the General Electrician total only up to 1,500 hours, so years of cabling work don't quietly build a General card, and a General card doesn't hand you this one either. If you want both, the application instructions price two exams at $275 against $175 for one, and each classification still needs its own hours under section 291.1 and its own approved curriculum under section 291.2(g).
CCR Title 8 section 290.1
Non-residential Lighting Technician
The shortest route of the five at 2,000 hours, covering retrofit and maintenance of nonresidential lighting.
CCR Title 8 section 291.1
| Hours | 2,000 hours of installing, repairing and maintaining nonresidential lighting while employed by a C-10 electrical contractor.CCR Title 8 section 291.1 |
|---|---|
| Caps | Stockroom and material handling 150, maintenance of lighting fixtures 1,750, installation of retrofit fixtures 1,500, troubleshooting and repairing 500. No single category reaches 2,000.CCR Title 8 section 291.1 |
| Exam | 50 questions, 2 hours 15 minutes, 70 percent to pass. Troubleshooting, replacement and retrofit is half the paper and lighting control another 22 percent.Candidate Information Bulletin |
| Books | The usual three on screen plus the Lighten Up! and Illuminations training textbooks, 4th Edition.Candidate Information Bulletin |
| Training | DIR names the NALMCO Certified Apprentice Lighting Technician program as the approved on the job training for this classification.DIR Non-residential Lighting Technician page |
| Scale | The smallest of the five. The statistics page dated April 12, 2023 counted 225 people holding it.ECU statistics, April 12, 2023 |
The NALMCO manual is training material, not a state approved apprenticeship
DIR names the NALMCO Certified Apprentice Lighting Technician program for this classification and then says on the same page that users of the manual are not participants in a State of California approved apprenticeship program. So the manual and a registered apprenticeship aren't interchangeable on your application, and section 291.2(g) still wants proof of the approved curriculum for the classification you're seeking.
DIR Non-residential Lighting Technician page
C-10 Electrical contractor license C-10
This is the license that lets you take the contract and pull the permit in your own name, and it comes from a different board on a different track.
Business and Professions Code sections 7008 and 7059
| Experience | Four years in the classification you apply for, credited only at journey level or as a foreman, supervising employee, contractor or owner-builder. Every claim needs verification by someone with firsthand knowledge.CSLB experience requirements page |
|---|---|
| Education | Education can stand in for up to three of the four years, and at least one year has to be practical experience.CSLB experience requirements page |
| Exams | Two, Law and Business plus the C-10 trade exam, 3 hours 30 minutes each and both closed book. Scheduling runs through PSI, and a retake waits 21 calendar days.CSLB examination FAQ |
| Deadline | 18 months from acceptance of the application to passing both papers.CSLB examination FAQ |
| Fees | $450 for an original application in one classification, plus an initial license fee of $200 for a sole owner or $350 for anyone else.CSLB fee list |
| Bonds | A $25,000 contractor bond and a $25,000 bond of qualifying individual where one applies, with proof of workers compensation coverage or an exemption.CSLB issuance page |
| Term | Active licenses expire every two years and inactive ones every four. Active timely renewal for C-10 is $470 for a sole owner and $720 for anyone else.CSLB general renewal page, CSLB fee list |
Holding a C-10 doesn't exempt your employees from certification
Electricians who make connections of greater than 100 volt amps for a C-10 contractor have to hold a state certification card or be registered electrician trainees. The sole owner exemption covers the owner alone, and C-7 and C-45 contractors are exempt only inside their own classification. Hiring your first employee also ends the workers compensation exemption, which is a condition of licensure. The FAQ names the board as the enforcement body for violations in the field.
ECU FAQ
Licensed in another state
There's no reciprocity for the California certification, so an out of state license buys you a seat at the exam rather than a card.
ECU FAQ
| Certification | No reciprocity at all. The unit says an out of state license will make you eligible to sit for the test, which is not the same as waiving it.ECU FAQ |
|---|---|
| Exam | The same paper as everybody else. General Electrician is 100 questions in 4 hours 30 minutes, and the 70 percent pass mark doesn't move for experience.Candidate Information Bulletin |
| Hours | Section 291.1 ties every qualifying hour to work for a C-10 electrical contractor and the FAQ doesn't say whether hours worked outside California count. Ask the unit at ECUINFO@dir.ca.gov or (510) 286-3900 in writing before you file.CCR Title 8 section 291.1, ECU FAQ |
| Fees | $175 for a single exam, described as non refundable, so get the hours question answered before the check goes out.ECU application instructions page, ECU FAQ |
| Meanwhile | You can work for a C-10 contractor as a registered electrician trainee while you wait, which takes enrollment in a state approved school and $25.DIR electrician trainee page |
| Contractor | CSLB holds reciprocity agreements with Arizona, Louisiana, Mississippi, Nevada and North Carolina, on an active license in good standing there for the previous five years.CSLB reciprocity page |
Nobody could confirm C-10 sits on any Reciprocal Classifications List
Contractor reciprocity depends on applying in a classification that appears on the other state's Reciprocal Classifications List, and the board keeps that list in a separate document that wasn't reached for these pages. So the five state agreement may or may not reach C-10 Electrical, and it's worth asking the board before you plan around it. The NASCLA route is no help here either, because it applies to the General Building classification only.
CSLB reciprocity requirements page
Renewing a certification card
Renewal comes round every three years, and the fee is the easy part of it.
CCR Title 8 section 291.5
| Term | Certification shall be renewed every three (3) years.CCR Title 8 section 291.5 |
|---|---|
| Education | 32 hours of further electrical education from an Educational Provider or from a state or federally approved apprenticeship program.CCR Title 8 section 291.5 |
| Work | A declaration under penalty of perjury that you have worked in the industry 2,000 hours within the previous three years.CCR Title 8 section 291.5 |
| Fees | $100 to renew. A replacement card is $30, which section 291.5 sets at 30 percent of the renewal fee in section 292.0(c).CCR Title 8 section 292.0, ECU fee page |
| Timing | The renewal has to be postmarked or received 30 days before the certification period ends. The unit answers within 30 days and a timely card arrives in about two weeks.CCR Title 8 section 291.5, ECU renewal form |
| Providers | Three groups under section 290.1: electrician trainee schools, federal or state apprenticeship programs, and other approved providers under contract with a California public educational institution.CCR Title 8 section 290.1, ECU continuing education page |
The 2,000 hour declaration is signed under penalty of perjury
2,000 hours across three years is a low bar for a full time electrician and an impossible one for somebody who stepped out of the trade for a while. You can't sign what isn't true, and if you can't sign it the renewal form points where a lapse points, to a $200 exam fee and another sitting of the certification exam. The 32 hours have to come from an approved provider too, and a course from a company with no contract with a California public educational institution doesn't obviously qualify.
CCR Title 8 section 291.5
A lapsed or expired card
A lapse doesn't cost you your hours, but the rule does send you back to the exam room.
CCR Title 8 section 291.5
| Rule | An individual who allows certification to lapse shall be required to retake the certification examination.CCR Title 8 section 291.5 |
|---|---|
| Fees | The ECU fee page prices renewal of a lapsed or expired certification card at $200, and the renewal form prices the retake at a $200 exam fee alongside the $100 renewal fee.ECU fee page, ECU renewal form |
| Exam | The same paper you sat the first time, at 70 percent, with the books supplied inside the testing system rather than carried in.Candidate Information Bulletin |
| Still owed | The 32 hours of further electrical education and the 2,000 hour work declaration don't go away because the card did.CCR Title 8 section 291.5 |
| Next time | The renewal has to be postmarked or received 30 days before the certification period ends, so the date to diary is a month early.CCR Title 8 section 291.5 |
Missing the work declaration lands where missing the date lands
Two different failures end in the same seat. Letting the card expire sends you back to the certification exam under section 291.5, and so does failing to meet the renewal requirements, which includes being unable to certify 2,000 hours of industry work over the three years. The renewal form prices both at a $200 exam fee. Keeping the provider certificates and renewing on time is the cheapest way to stay out of that room.
ECU renewal form
Adding a certification, or moving up to General
Nothing stops you holding more than one card, and the fee schedule is built on the assumption that people do.
ECU application instructions page
| Fees | $175 for one exam, $275 for two and $375 for three, so a second classification applied for at the same time costs $100 rather than another $175.ECU application instructions page |
|---|---|
| Hours | Each classification needs its own hours under section 291.1, and every one of them has to be worked for a C-10 electrical contractor.CCR Title 8 section 291.1 |
| Curriculum | Proof of completing the approved curriculum for the classification you're seeking goes in with the application.CCR Title 8 section 291.2(g) |
| Moving up | General Electrician asks for 8,000 hours across two or more work areas. Residential wiring is capped at 3,000 of them and voice data video installation at 1,500.CCR Title 8 section 291.1 |
| Exam | One paper per classification. General is 100 questions, Residential 80 and the three technician cards 50 each, all at 70 percent.Candidate Information Bulletin |
Hours in one specialty don't carry over whole into the General total
The caps decide what your existing work is worth on a second application. Inside the 8,000 hours for General, residential wiring stops at 3,000, voice data video installation at 1,500, troubleshooting and maintenance at 1,500, and Fire/Life Safety and nurse call at 600. A career spent inside one specialty can't reach 8,000 on that line alone, which is why the General card asks for two or more work areas. Count your hours against the ceilings before you pay for a second exam.
CCR Title 8 section 291.1
Renewing a C-10 contractor license C-10
The contractor clock runs on its own schedule, and it asks for a fee and a form rather than a class.
CSLB general renewal page
| Term | Active licenses expire every two years and inactive licenses every four.CSLB general renewal page |
|---|---|
| Fees | Active timely renewal in the C-10 classification is $470 for a sole owner and $720 for anyone else, against $450 and $700 in other classifications.CSLB fee list |
| Late | Active delinquent renewal is $695 for a sole owner and $1,070 otherwise. Senate Bill 1474 allows 90 days after expiration to file a completed renewal with fees and be reinstated retroactively.CSLB fee list, CSLB general renewal page |
| Continuing education | The board's general renewal page names none for contractors. The 32 hours belong to the certification card, not to the license.CSLB general renewal page |
| Inactive | Inactive timely renewal is $300 for a sole owner and $500 otherwise, and reactivation is $450 and $700.CSLB fee list |
Renewing the license doesn't renew anybody's certification card
A licensed C-10 business can employ people whose certification has lapsed, and checking one record doesn't answer the other. Cards run on three years and the license on two, and a lapsed card sends that electrician back to the certification exam rather than to a late fee. The DLSE certification search and the board's license check are separate lookups. The $20 a C-10 renewal carries above other classifications is the electrician certification surcharge, and it doesn't buy anybody a renewal.
CCR Title 8 section 291.5
Work in a city you do not know
No California city issues a competing electrician license, but a couple run registrations that sit on top of the state card.
Los Angeles County Electrical Code Title 27 section 82-4
| Los Angeles County | Public Works issues a Certificate of Registration as a Maintenance Electrician for an electrician permanently employed by a firm to work on that firm's own premises, on two years of experience in that capacity with that firm. No exam is described, and it expires on June 30 biennially in even numbered years.LA County maintenance electrician page |
|---|---|
| That fee | Printed two ways. The county certification page says $222.10 and the 2026 County of Los Angeles Electrical Code says $305.26. Call (626) 458-3170 before you write the check.LA County maintenance electrician page, 2026 County of Los Angeles Electrical Code |
| San Francisco | A state licensed contractor registers with the Department of Building Inspection before filing electrical permits online, and a surcharge of up to 2.5 percent with a $2.00 minimum applies to the filing.SF register as a city licensed contractor page |
| City of Los Angeles | No city issued electrician license or registration appears on the LADBS pages. Electrical permits are required for any electrical work, through Express Permit, Counter Plan Check or Regular Plan Check.LADBS electrical permits page |
| San Diego | No city issued license either. An electrical permit goes only to a licensed California state contractor authorized to do electrical work, or to the property owner or lessee.City of San Diego electrical permit page |
Ask LADBS which code edition your plan check runs against
The county adopts the state book. Title 27 of the Los Angeles County Code takes the 2025 California Electrical Code by reference, effective January 1, 2026. The city is less clear on paper. LAMC section 93.0700 adopts the National Electrical Code, the California Electrical Code and the California Building Standards Code by reference without printing an edition year, and the code library page for that article was read as referencing the 2022 California Electrical Code. The city's adoption of the 2025 edition couldn't be confirmed.
