What is Low Voltage? Key Concepts & Definitions
What “Low Voltage” Really Means
- Definition: Low voltage refers to electrical systems running at a voltage significantly lower than standard mains/higher‑voltage power lines. In many U.S. contexts, low voltage systems are those operating at 50 volts or less (although in California “low voltage” classification under CSLB C‑7 covers systems up to 91 volts in some cases). Low Voltage Nation+1
- Why it matters: Lower voltage means lower risk of severe electric shock, smaller wiring profiles, often simpler regulatory standards (though still regulated), and suitability for many safety, communications, and automation applications.
What Low Voltage Is Not
- Not the same as high voltage or line voltage circuits (e.g. 120V / 240V electrical wiring, power for ovens, etc.).
- Excludes work like main electrical panels, high‑capacity feeders, etc.
- Fire alarm systems sometimes have different licensing or safety rules. In California, for example, certain fire system work may be excluded from the C‑7 license scope. Low Voltage Nation+1
