High-voltage means that the highest voltage in normal conditions, either between the two connectors or between one connector and the ground, exceeds the following values:
- for alternating current: 1000 V;
- for direct current: 1500 V.
Reason:
The Low Voltage Directive 2014/35/EU states in Article 1 that “This Directive shall apply to electrical equipment designed for use with a voltage rating of between 50 and 1 000 V for alternating current and between 75 and 1500 V for direct current“.
