What does "high voltage" refer to?

"High voltage" commonly refers to any voltage that is 600 volts or more. This classification is important in the electrical field because it signifies a level of potential risk and necessitates specific safety measures and standards for handling, installation, and maintenance. The significance of this classification lies in the fact that voltages at or above this threshold can pose greater hazards, including electric shock and arc flash, thus requiring specially trained personnel and identified safety protocols.

The range of voltages below this threshold does not fall into the "high voltage" category and are typically treated under different safety regulations and training requirements. Understanding this classification aids workers in recognizing the necessary precautions and procedures needed when working with or around high voltage systems, ensuring both safety and compliance with electrical industry standards.
