Why is knowledge of voltage important for signal technicians?

Knowledge of voltage is crucial for signal technicians primarily because it enables them to ensure that circuits are designed safely. Understanding voltage levels allows technicians to assess the electrical requirements of different components and systems they may be working with. This knowledge helps prevent situations such as over-voltage that could damage equipment or pose safety risks to personnel.

Technicians must consider voltage to adhere to safety standards and regulations, thus protecting both infrastructure and personnel throughout the installation, operation, and maintenance of signal systems. By being well-versed in voltage and its implications on circuit design, technicians can mitigate potential hazards, ensuring reliable and safe operation of electronic and electrical systems.
