As the construction industry grows each year, businesses and employers with more at stake are turning to skilled tradesman with proven competency for their projects. Proof of skills and experience is a critical factor in your ability to get a high paying job or earn a lucrative contract. I have helped thousands of electricians around the state of California get their electrical certification.

Everyone wants to earn more money and ultimately gain more freedom. In today’s market, simply having the skills is not enough. You must have documented proof to back up your wage demands. The following article will break down everything you need to know about the electrical certification process in California. 

What is an Electrical Certification?

A certification is an official document that proves an individual’s experience or level of competency. In California, all electricians that are working under a C-10 electrical contractor or making connections of greater than 100 volts must hold an electrical certification. Protecting the interests of the public is something that is taken very seriously in the state of California. So laws have been put into place to protect the interests of the consumer public.

What is an Electrical Contractor

A contractor is someone who has proven a minimum of 4 years journey level experience and passed both the California contractor LAW and TRADE examination. A contractor is legally allowed to bid on an electrical project where the cost of labor and materials exceeds $500. Electrical companies doing large projects and individual electricians working in a residential or commercial setting, hold the C-10 license. An electrical contractor will hold the license and place the bid, but they may have someone helping them and performing tasks. This person must hold an electrical certification. An individual holding the C-10 license does not need an electrical certification.

Contractors State License Board

The Contractors State License Board is the governing agency for contractors in the state of California. They ensure that anyone charging over $500 for construction services has a contractor license and active bond. They have offices all over the state and conduct sting operations to combat unlicensed construction activity.

Division of Labor Standards Enforcement

The Division of labor standards enforcement is an agency that functions under the California Department of Industrial Relations. This branch of government handles everything from safe working conditions and fair compensation to enacting labor standards for specialized tradesman. Everything about electrical certifications, tests, fees, and certification renewals is handled by the Division of Labor Standards Enforcement.

What is the NEC?

The electrical certification exam is based on standards set by the National Electrical Code. Electrical codes similar to other construction codes are typically adopted regionally. They are standards put in place to ensure a level of quality associated with construction. The goal of the NEC is to create a standard for the safe installation of electrical wiring or equipment ideally reducing the hazards associated with an unsafe electrical system set up. As of 2018, twenty-six states have adopted the national electrical code as their standard. The NEC code book is updated every three years. The electrical certification must also be renewed to reflect updated wiring practices. Some of the key concepts that you must know are:
