C-7 is a specific California contractor classification, not an all-purpose low-voltage or fire-alarm license. Each CSLB examination allows 3.5 hours; CSLB does not publish a fixed C-7 item count or fixed passing percentage. A contractor license is required at $1,000 or more, or at any price when a permit or employee labor is required.

1Which California state agency issues the C-7 Low Voltage Systems Contractor license?
A.California Department of Consumer Affairs
B.Contractors State License Board (CSLB)
C.California Energy Commission
D.California Building Standards Commission
Explanation: The Contractors State License Board (CSLB) issues the C-7 Low Voltage Systems Contractor license in California. The CSLB regulates the construction industry, processing license applications, investigating complaints, and enforcing contractor licensing laws statewide.
2When does California generally require a contractor license for a C-7 project under the current minor-work exemption?
A.Only when the total project cost exceeds $5,000, with no separate scope, credential, or local permit requirements for any system
B.Permit required, employee labor used, or project total at least $1,000
C.Only when materials alone cost $1,000 or more
D.Never for an energy-limited system
Explanation: The minor-work exemption applies only when the combined project cost is less than $1,000, the work does not require a building permit, and no employee labor is used. If any one of those conditions is not met, the exemption does not apply. A larger project also cannot be split into smaller contracts to evade licensure.
3Which statement accurately describes the California C-7 classification?
A.It covers all electrical work below 600 volts, with no separate scope, credential, or local permit requirements for any system
B.Energy-limited systems at 91 V or less, excluding fire alarm
C.It covers only telephone wiring
D.It is a fire alarm-only classification
Explanation: CSLB defines C-7 as communication and energy-limited low-voltage systems not exceeding 91 volts. Examples include telephone, sound, cable television, CCTV, satellite, instrumentation, temperature controls, and low-voltage landscape lighting. Low-voltage fire alarm systems are expressly excluded.
4How many years of journey-level experience does California typically require for a C-7 license?
A.1 year
B.2 years
C.4 years
D.6 years

5What is the minimum surety bond amount required for a California C-7 contractor?
A.$10,000
B.$15,000
C.$25,000
D.$50,000

The bond amount was increased from $15,000 to $25,000.

A.Workers comp is optional
