  1. A C7 contractor discovers existing low voltage wiring in a wall that is not labeled or identified. What is the first required action before proceeding with work near it?

    Answer: De-energize and test the circuit to verify it is safe

    Before working near unidentified wiring, Cal/OSHA and NFPA 70E require de-energizing and testing to confirm the circuit is safe (lockout/tagout procedure).

  2. According to the NEC, low voltage wiring installed in raceways must be separated from power conductors by how much unless it uses a barrier?

    Answer: Must occupy separate raceways entirely

    NEC Article 725 generally requires Class 2 and Class 3 wiring to be separated from power wiring in separate raceways unless using approved barriers or cables with sufficient insulation ratings.

  3. Which California agency is responsible for enforcing electrical code compliance on general construction job sites?

    Answer: California Division of Occupational Safety and Health (Cal/OSHA)

    Cal/OSHA enforces electrical safety standards on California construction job sites, including compliance with Title 8 electrical safety orders.

  4. Under the CEC, what does the term 'listed' mean when applied to low voltage equipment?

    Answer: Evaluated and found to meet safety standards by a nationally recognized testing laboratory (NRTL)

    Listed equipment has been evaluated by a Nationally Recognized Testing Laboratory (NRTL) such as UL or ETL and found to meet applicable safety standards.

  5. A C7 contractor wants to install security camera wiring (CCTV) in a building. Which NEC article primarily governs this installation?

    Answer: Article 820 (Community Antenna Television)

    NEC Article 820 covers coaxial cables used for community antenna television (CATV) and CCTV distribution systems.

  6. What does the California Building Code require regarding seismic bracing for low voltage system components mounted above suspended ceilings?

    Answer: Components over 20 lbs must be independently seismically braced

    California's adoption of ASCE 7 seismic requirements mandates that mechanical and electrical components (including low voltage equipment) weighing over 20 lbs above suspended ceilings must have independent seismic bracing.

  7. Under California law, a C7 contractor who subcontracts work must ensure the subcontractor holds which minimum license?

    Answer: An appropriate specialty or general contractor license for the work performed

    California Business and Professions Code requires that subcontractors performing licensed work hold an appropriate contractor's license for the trade or specialty they perform.
