High voltage is defined by the voltage level that requires stricter safety controls, insulation, and PPE. In this context, the line is drawn just above 600 volts, so anything 601 volts or higher is treated as high voltage. That threshold is what triggers enhanced safety procedures, training requirements, and appropriate protective gear. While voltages like 4 kV or 69 kV are clearly high voltage, the question points to where the high-voltage category begins, which is 601 volts and above.
