Well, California now has a State Journeyman Electrician Certification and it is required to do Electrical work in California. They do not have a Master Electrician License, however if you want to be an electrical contractor, they do have a (C-10) Electrical Contractors license......the exam is electrical and business and law. The State Journeyman Electrician License exam is given by PSI and all you need to do is apply to the State of California with 4 years (8,000 hours ) of trade experience and a copy of your out of State License and $150 and when approved sit for the exam.......
Hope this helps.....
