1. High voltage

High voltage refers to an electrical potential large enough to cause harm to people, animals, or equipment, typically above a defined threshold (varies by standard, but often above 1,000 volts AC or 1,500 volts DC).

  • Road signs may warn of overhead electric cables near railway crossings, tram routes, or construction sites.
  • Special caution is needed for tall vehicles (trucks, cranes) passing under power lines.
