What is the threshold voltage that distinguishes low voltage from high voltage?

The distinction between low voltage and high voltage is generally accepted in electrical safety and engineering standards. The threshold voltage that separates low voltage systems from high voltage systems is typically set at 1000 volts. This classification is based on the potential danger associated with the level of electric shock and the necessary precautions required for safety.

Below this threshold, systems are often regarded as low voltage and thus have fewer safety regulations regarding insulation and employee training. Once the voltage exceeds 1000 volts, it is regarded as high voltage, necessitating more stringent safety measures, specialized training for personnel, and enhanced protective gear to mitigate the risks associated with electrical hazards. This classification helps in establishing proper protocols for handling, maintenance, and emergency responses in environments where electrical systems are present.
