Different Types of Electricians
Commercial, residential, and industrial maintenance electricians share the identical state certification exam required by the CA Department of Industrial Relations. However, trade knowledge, electrical systems, and common materials can be completely different between these electrical sectors.


The exams are not the same, and there isn't any even a requirement or classification for maintenance. There are General Electricians, and Residential Electricians

Further, the national electrical code (NEC) is modified every three years, and many electricians do not keep track of locally adopted code changes. No electrician can know it all, passing inspection the first time is never guaranteed, and matching the most economical material with the most current-code listings can require considerable time and effort.
The people issuing permits at your local building department are not reliable at identifying which NEC code cycle is currently adopted in your city, much less is your favorite electrical contractor, unless they take the time to visit your city’s building department and inspect the code book themselves.


The reason that they do not know what version of the NEC the City of Fullerton is on is because they are on the Fullerton Electrical Code, not the NEC. The Fullerton Code is amended in only a couple of areas from the 2004 California Electrical Code, still not the NEC, which is adopted from the 2002 NEC in and is in effect in the entire State of California.

There's no reason to go down to the building dept and read the book. The City's website has the entire Municipal Code, including the Electrical Code.

Do yourself a favor, get a license, and get legit.

BTW I'm a C10 from Fullerton.
