differences of potential normally existing between conductors and between conductors and earth as follows: - extra-low voltage: not exceeding 50 V a.c. or 120 V ripple-free d.c.;
- low voltage: exceeding extra-low voltage, but not exceeding 1 000 V a.c. or 1 500 V d.c.;
- high voltage: exceeding low voltage
Note 1 to entry: In consideration of ELV status, VOC ARRAY shall be used. |
