At what voltage level is electricity considered high voltage?

Electricity is generally considered to be high voltage starting at levels of 1000 volts and above. This threshold is significant because it indicates the point at which special safety protocols, protective equipment, and safety training become necessary due to the increased risk of electric shock and arc flash hazards. High voltage requires a different set of handling procedures and equipment to ensure the safety of workers and the integrity of electrical systems.

Understanding this distinction is crucial for linemen and those working with electrical systems, as it aids them in recognizing the potential dangers and the appropriate measures to mitigate risks when engaging with high voltage lines and equipment. The other voltage levels listed—500 volts, 750 volts, and 1200 volts—either fall below this accepted high voltage threshold or do not represent common classifications in existing electrical safety standards. As such, they do not qualify as high voltage according to industry definitions.
