California temp power license: what you actually need

Last updated 2026-08-18

Do you need a license for temp power in California?

The short answer is yes for almost all paid electrical hookups. California has no separate temp power license. The state's contractor licensing law treats temporary power distribution as electrical contracting work. Business and Professions Code section 7048 says any person who contracts to do work on a project where labor and materials total $500 or more needs a contractor license ^[1]. Business and Professions Code section 7058 places that work in the C-10 Electrical Contractor classification ^[2].

So if you install a temporary power pole, set a spider box, run temp cable, or connect a generator to a panel for a client, you are operating as an electrical contractor. That means a C-10.

There is an exception. If you only drop off a generator and the customer does their own connection, or if the whole job stays below the $500 threshold, you may not need the C-10. But most real temp power jobs land over $500 fast.

Workers on the job have a separate layer. California's Division of Apprenticeship Standards runs electrician certification, and electricians who perform the actual hookup work generally need to be certified ^[7]. A C-10 holder can own the company, but the people touching wires need their certification. I would not rely on an unlicensed handyperson for a temp power connection. Inspectors check.

If you plan to run temp power in other states later, the California C-10 does not automatically convert. Temp power license in Texas and temp power license in Arizona show two very different first steps.

How much does temp power cost in California?

The honest answer is that no public dataset tracks full temp power project costs. The bill splits into four pieces: CSLB license fees, bond and insurance, labor, and equipment or permit fees. The CSLB fee schedule lists a $450 application processing fee for an original contractor license and a $200 initial license fee for an active license ^[3]. That is $650 before you buy a bond, insurance, books, or an exam seat.

The contractor bond is set by statute at $15,000 ^[6]. You usually pay a fraction of that as premium, often $100 to $250 depending on credit. Workers' compensation insurance is required when you have employees, and California Labor Code section 3700 imposes the obligation ^[5]. Many one-person C-10 shops need a certificate of exemption if no employees, but that does not protect you if you put a friend on the job.

Labor is the biggest variable. U.S. Bureau of Labor Statistics data reported a mean hourly wage of $39.68 for electricians in California in May 2023, compared with $31.65 nationally ^[11]. A two-person temp power crew can easily cost $80 to $120 an hour loaded with workers' comp and other overhead. Materials and permits add more.

Local permits should be budgeted case by case. Los Angeles, for example, requires electrical permits for installations and publishes a specific fee schedule ^[9]. Utility temporary service applications also have their own fees and deposit rules. PG&E's temporary construction power page describes the service path, inspection, and requirements ^[10].

You can put together a bare legal startup for around $1,000 to $2,000 in state and insurance costs if you are a one-person C-10 operation with no employees. That does not include the actual equipment, tools, or your time. If someone quotes you a total temp power job under $500, check the scope. Real projects run higher.

How long does temp power take in California?

Plan for at least several weeks of state paperwork before you can legally pull a temp power permit as a C-10. CSLB posts current processing times for original applications, including document review and exam scheduling ^[4]. The board's posted times move, and no date is a guarantee. In practice, a clean original C-10 application with verified journey-level experience can move through in about three to eight weeks. An incomplete application can stretch to months, so the paper quality matters.

After state approval, local building department permit review and utility temporary service approval add their own clock. A city permit can be same day for a simple temp pole or several weeks if the plan review queue is long. Utility temporary service often requires a licensed electrician to call for inspection and may add days to a few weeks. PG&E outlines inspection and connection steps on its temporary construction power page ^[10].

The fastest path is not a shortcut. It is having your four years of journey-level experience documented, your $15,000 bond ready, and your workers' comp or exemption form complete before you file. How to start temp power in California covers first-year operations and what to order first.

What does a C-10 license actually cover for temporary power?

The C-10 Electrical Contractor classification covers contracts that require the experience and means to install, erect, or connect electrical power, lighting, and control systems ^[2]. A temp power panel, spider box, cam lock connection, feeder cable, and generator tie-in all sit inside that scope.

The license does not cover mechanical work, plumbing, or structural work. If you set a temp pole on a concrete pad and run conduit, that is electrical. If you build a small platform or trench and repair sidewalks, you may cross into another classification or a general building license. Keep the scope tight or bring a sub.

For event temp power, the same C-10 rules apply. A concert promoter cannot bypass the contractor license by calling it production. If you are paid to distribute power and the job is over $500, you are an electrical contractor.

What about a single event? The $500 threshold is per project, not per year. One weekend festival with labor and materials over $500 triggers the license.

Do you need certified electricians on a temp power job?

Yes for the actual wiring work. California's electrician certification program, run under the Division of Apprenticeship Standards, requires electricians who work for a C-10 contractor to hold a state certificate ^[7]. A C-10 owner can run the company, but if they touch the wire themselves, they still need their own electrician certification.

There are exceptions for apprentices registered with a state-approved program and for certain narrow maintenance work. A temp power connection on a construction site is not the place to argue the exception. The inspector will ask for the certified electrician's card.

Most C-10 qualifiers I talk to recommend that every person doing termination and live connection carry a current card and have their hours logged. It protects the job and keeps your workers' comp claim cleaner.

California is stricter than many states on this point. That is why temp power license in Texas has a different paper path and less worker-level certification in some scopes.

What permits apply to temporary power poles and generator hookups?

Local building department electrical permits are the layer people forget. A temp power pole for a construction site generally needs an electrical permit from the city or county. Los Angeles, for example, runs its own electrical permit process ^[9]. Your C-10 number goes on the permit application. If you do not have a C-10, you cannot pull the permit in your own name.

Utility temporary service is separate. The utility will require a service application, a meter spot, and an inspection before energizing. PG&E's temporary construction power page lists the steps for its service territory ^[10]. Other utilities have parallel instructions. Do not assume one utility's rules cover another.

The electrical installation itself follows National Electrical Code Article 590, which California adopts through the California Electrical Code. Article 590 covers temporary wiring methods, GFCI protection, overcurrent protection, and feeder disconnects ^[8]. Your setup needs to meet those rules, more than the utility's meter requirements.

If you are doing event temp power on private land, the local fire marshal may also inspect cable runs, generator placement, and egress. That is not a license, but it blocks the show.

What equipment and documents do California inspectors ask for?

Most inspection failures on temp power are not missing paper. They are missing UL listing, missing GFCI, or missing disconnects. Article 590 expects temporary wiring to have overcurrent protection and GFCI protection for 15-, 20-, and 30-amp receptacles used by workers ^[8]. Bring test records and panel schedules.

Inspectors generally ask for the C-10 license number, the electrician certification card for the worker making terminations, the local electrical permit, and the utility job number. Keep the panel directory and a one-line diagram in your glove box.

For generators, have the grounding method documented. Article 590 and generator manufacturer instructions set the grounding and bonding requirements. An inspector will want to see the generator frame bond and the neutral-ground connection decision.

TempPowerPath is an independent publisher, not a law firm and not a service company. Its $179 one-time Cable + Fuel + 480V Kit is a reference collection, not a substitute for the local inspector's checklist.

Does home state reciprocity help? Probably not the way people hope

California has almost no contractor license reciprocity for electrical contracting. A license from Texas, Arizona, Nevada, or another state will not let you pull a California C-10. CSLB may consider out-of-state experience toward the four years of journey-level work, but you still sit for the California exam and meet California bond and insurance rules.

This matters because people move to California for event and construction temp power work and assume their out-of-state company can operate. It cannot for electrical work over $500.

The reverse is also true. A California C-10 does not automatically authorize electrical contracting in other states. Temp power license in Arizona and temp power license in Alabama show how different the thresholds and boards can be.

For a multi-state operator, the practical move is separate licenses or a partner with the home state license in each jurisdiction. No national temp power license exists.

What insurance and bond does a California temp power contractor carry?

CSLB requires a $15,000 contractor bond for a C-10 license ^[6]. That bond protects consumers, not the contractor. Premiums typically cost a few hundred dollars a year, but the exact rate depends on credit and underwriter. Do not confuse it with general liability insurance.

General liability is not a statutory license requirement, but almost every venue, general contractor, and utility site will ask for it. A $1 million per occurrence / $2 million aggregate policy is the common baseline for event temp power. Premiums vary by revenue and loss history.

Workers' compensation is the legal layer. California Labor Code section 3700 says, "Every employer except the state shall secure the payment of compensation" ^[5]. If you have no employees, you can file an exemption, but the moment you pay a helper cash, that exemption becomes a liability. I would not run a temp power job without a clear workers' comp status in writing.

Some utilities also require evidence of insurance naming the utility as an additional insured before they set a temporary meter. Ask for the exact form early.

What is the real application paper path in California?

Order matters. Start with the CSLB original contractor application for a C-10 classification. You need a qualifier with at least four years of journey-level electrical experience, documented with a certified statement of experience. The application fee is $450, and the initial license fee is $200 for an active license ^[3]. You will also need the bond and a workers' comp certificate or exemption before CSLB issues the license.

The qualifier then passes the CSLB electrical trade exam and the law and business exam. The trade exam covers the California Electrical Code, load calculations, services, and safety. Study from the actual code, more than a question bank.

After CSLB issues the C-10, go to the local building department for a permit, then to the utility for temporary service. Keep a file with license number, bond number, insurance certificate, electrician certification cards, and the job's one-line diagram.

If you want a fast reference rather than another blog, how to start temp power in California walks through first-year operations and purchasable equipment. But the source documents are free from CSLB and your local building department.

Where do people mess up temp power licensing in California?

The biggest mess is bidding work before the C-10 exists. You cannot legally sign a contract for electrical work over $500 without the license. If you take a deposit and the job falls apart, you may have no standing to collect.

Another mess is using an unlicensed sub or a rental-yard helper. The C-10 holder remains responsible for the work, and the worker still needs electrician certification ^[7].

A third mess is ignoring local permits. A state license does not waive city electrical permits. A utility will not energize most temporary services without signed local inspection.

The fourth mess is underestimating the paper lead time. CSLB processing times are published but not guaranteed ^[4]. Utility service can add weeks. Book the meter spot and permit application the same day you sign the job.

If you are comparing states, temp power license in Alaska has a different operator path entirely. Do not copy it for California.

When is a temp power license not required in California?

Three narrow cases usually do not require a C-10. First, a homeowner doing their own single-family residential electrical work may do it without a contractor license, though local permit and inspection still apply. Second, a job below the $500 labor-and-materials threshold does not require a contractor license ^[1]. Third, a pure equipment rental with no connection work is not contracting.

None of those cases cover the typical paid temp power setup. A generator rental company that also plugs in cables and ties into a panel is doing electrical contracting, not rental. The moment the worker touches a conductor for pay, the C-10 and electrician certification questions start.

For employees of a facility, such as a full-time electrician working on a plant's own equipment, the contractor license requirement can differ. But the worker still needs certification on the electrical side in most California construction and maintenance settings. Confirm with the local building department for the specific site.

What should you do in your first 30 days after getting approved?

Open the paper file, more than the tool bag. Make copies of your C-10 license, bond, insurance certificate, workers' comp status, and electrician certification card. Put them in the truck and a cloud folder. A temp power inspector will ask for them on the first job.

Apply for a temporary service in your own name or for your first client only after the local permit is pulled. Keep the permit number visible at the temp pole.

Practice the scope. Start with a basic temp power pole or small generator distribution before taking a 1000-amp event feed. The code rules in Article 590 will get tested under load ^[8].

Set your rates using the BLS California electrician wage plus overhead, more than the wage. A mean hourly wage of $39.68 for electricians in California is the labor floor before taxes, workers' comp, and vehicle costs ^[11]. Pricing below loaded cost is the fastest way to lose money in a licensed trade.

And get the document set in one place. TempPowerPath's reference kit exists for $179 one time, but the authoritative source documents from CSLB, DIR, NFPA, and your local building department are free. Read those first.

Frequently asked questions

Do you need a license for temp power in California?

Yes for paid electrical hookups. California has no temp power specific license. Any person contracting for electrical work where labor and materials total $500 or more needs a C-10 Electrical Contractor license from CSLB. Workers performing the wiring also need DIR electrician certification. Pure equipment rental with no connection work may not.

How much does temp power cost in California?

State license application and initial license fees total $650, not counting bond, insurance, exams, or local permits. The contractor bond is $15,000, with annual premium usually a few hundred dollars. Electrician labor averages $39.68 per hour in California. A one-person C-10 startup often budgets $1,000 to $2,000 before equipment.

How long does temp power take in California?

CSLB processing times for an original C-10 application often run three to eight weeks if the file is clean. An incomplete application can take months. Local permits and utility temporary service approval add days or weeks after state approval. No stage has a guaranteed date, so book early.

Can I do temp power with an electrician certification but no contractor license?

No for contracting work over $500. An electrician certification lets you work as an employee or under a C-10 contractor, but it does not let you sign contracts or pull permits in your own name for electrical contracting. You need both the C-10 for the company and certification for the workers doing the terminations.

Does California have a separate temp power license?

No. Temporary power distribution is not its own classification. It falls under the C-10 Electrical Contractor classification. Local permits and utility temporary service approvals are separate administrative steps, but the state license is the C-10.

Can I use an out-of-state electrical license in California?

No. California does not grant reciprocal contractor licenses for electrical work. Out-of-state experience may help you qualify for the C-10 exam, but you must still apply to CSLB, pass the California trade and law exams, and meet California bond and insurance rules.

Do I need a permit for a temporary power pole?

Yes in most cities and counties. A temp power pole typically requires a local electrical permit. The permit application usually needs a valid C-10 license number. The utility will also require its own temporary service application and inspection before energizing the meter.

What insurance do I need for temp power work in California?

You must have a $15,000 CSLB contractor bond. If you have employees, workers' compensation is required by law. General liability is not required by CSLB but is standard for venues, utilities, and general contractors, commonly $1 million per occurrence / $2 million aggregate.

Can a handyperson set up a generator for an event?

Not if the work involves connecting or distributing electrical power for pay above the $500 threshold. That is electrical contracting and requires a C-10 plus certified electricians. A handyperson can deliver a generator, but the electrical connection needs a licensed contractor.

How do I verify a C-10 contractor in California?

Use CSLB's online license check. Search by name, license number, or business name. Confirm the license is active, the classification is C-10 Electrical Contractor, and the bond and workers' comp status are current. Do not accept a paper copy alone.

What is the $500 rule for temp power?

Business and Professions Code section 7048 requires a contractor license for any project where labor and materials total $500 or more. Temp power jobs rarely stay under that total. The threshold applies per project, not per year, so a single event hookup can trigger it.

What is Article 590 in temp power work?

Article 590 of the National Electrical Code, adopted in California's Electrical Code, sets rules for temporary wiring. It covers overcurrent protection, GFCI protection for 15, 20, and 30 amp receptacle outlets, grounding, and feeder disconnects. Inspectors use it as the baseline for temp power installations.
