Can anyone tell me what the uk mains voltage classifications are.
i.e. what range of voltages are covered by low, medium, & high voltage ?

Low below 11 kV Medium below 132 kV High 132 - 400 kV
Low voltage 50-1000V A.C. and high voltage 1000V-52000V A.C.
So DC doesn't count?
Extra-low voltage -- not exceeding 50 V AC or 120 V ripple free DC. Low voltage -- exceeding extra-low voltage, but not exceeding 1000 V AC or 1500 V DC. High voltage -- exceeding low voltage.
The question has already been answered by an earlier posting, but my comments relate to the statements regarding extra low voltage. According to IEC/EN 60950-1 ELV are voltage levels that do not exceed 42.4V peak or 60V DC. The European Low Voltage Directive applies to voltages between 50 - 1000VAC and 75 - 1500VDC, anything higher is high voltage and anything lower is low voltage.
