   Most hardware is actually manufactured in China, where the mains is 220
+/- 10 volts, and they have been under the impression that UK mains is 240
volts, which would be within their equipment tolerance. In fact the UK
should now meet EU regulations which specify 230 volts +/- 10% (so up to 253
volts), although in many areas it actually approaches 260 volts on light
loading, without taking into account occasional spikes. This requires a
change of components. Add possibly poor quality manufacturing and it starts
to become cost effective to return manufacturing to the UK.
