C-10

C-10 — Electrical contractor

The Contractors State License Board's name for this class is C-10 — Electrical. This page says what the work is, in ordinary words, and links to the board's own description. It is not an exam course.

What the class covers

A C-10 contractor does the electrical work on a building or a site: the wiring, the panels, the fixtures, and the equipment that carries or uses electrical power. That includes battery storage and solar when the work is part of the electrical system. The sentence that controls the class is the board's regulation, and the board can change it. Read that page before you decide a job is inside or outside the license.

Holding C-10 is a line on a license, next to any other class the same license carries. Look up the license to see whether C-10 is actually on it, and whether the license is active on the file date.
