International Electrotechnical Commission

differences of potential normally existing between conductors and between conductors and earth as follows:

a) extra-low voltage: not exceeding 50 V a.c. or 120 V ripple-free d.c.;

b) low voltage: exceeding extra-low voltage, but not exceeding 1 000 V a.c. or 1 500 V d.c.

c) high voltage: exceeding low voltage.

NOTE In consideration of ELV status, VOC ARRAY must be used.
