The state of California classifies a licensed C-7 contractor as someone who can work on low-voltage systems. A licensed C-7 contractor can work on systems that don’t exceed 91 volts, such as telephone systems, satellite dish antennas, closed-circuit video systems, cable TV systems and landscape lighting. However, a licensed C-7 contractor cannot work on low-voltage fire alarm systems. A contractor can obtain a C-7 license by following the general rules to become a licensed contractor in California and passing a class “C” test for specialty contractors.
