  • High voltage - Wikipedia

    High voltage electricity refers to electric potential large enough to cause injury or damage. In the United States, the National Electrical Manufacturer Association (NEMA) defines high voltage as over 100 to 230 kV. up to only 30 volts between conductors, and may not be permitted to work on mains-voltage circuits.
