   It doesn't make much sense to me; ask, instead, the power company to   
   adjust the line voltage to an acceptable value.   The taps in their   
   transmission line drops are the solution to many such problems, if   
   they know that you have found an excessive voltage.   I'm not sure   
   250V average is excessive, but if there are peaks and dips...
