[QUOTE="PC Electrics, post: 162705, member: 650"] No. In the 'good old days' of pre-17th, the official UK mains voltage was 240 volts. So all devices were rated at 240 volts. Now that the official voltage is 230 volts, that same device has a lower wattage rating (it's recieving 10 volts less now). But, the manufacturers of showers (and maybe other items) still quote their 240 volt rating because the figure is higher (the marketing boys no doubt believe it gives them an 'advantage'). [/QUOTE]
