Actually the mains voltage is only a nominal voltage, and regulations allow for a percentage variation around that nominal voltage. If you read the quote below from Wikipedia, you will see that the UK is still generally outputing 240V, despite what the Daily Mail might like to say.
In my place I normally get about 240V during the day, and up to 250V at night - according to the TP. quote from Wiki: "Following voltage harmonization all electricity supply within the European Union is now nominally 230 V ± 10% at 50 Hz [1]. For a transition period (19952008), countries who previously used 220 V will use a narrower asymmetric tolerance range of 230 V +6% −10% and those (like the UK) who previously used 240 V use now 230 V +10% −6%[2]. Note that no change in voltage is required by either system as both 220V and 240V fall within the lower 230 V tolerance bands (230 V ±6%). In practice this means that countries such as the UK that previously supplied 240 V continue to do so, and those that previously supplied 220 V continue to do so. However equipment should be designed to accept any voltages within the specified range. In the United States[3] and Canada[4], national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 to 126 V (-5% to +5%). Historically 110, 115 and 117 volts have been used at different times and places in North America.[citation needed] Main power is sometimes spoken of as one-ten; however, 120 is the nominal voltage." http://en.wikipedia.org/wiki/Mains_electricity for the whole article. -- bigfool1956 David Ayers Music is what counts, hifi just helps us enjoy it more ------------------------------------------------------------------------ bigfool1956's Profile: http://forums.slimdevices.com/member.php?userid=13782 View this thread: http://forums.slimdevices.com/showthread.php?t=50634
