Our mains voltage can vary, depends who's got the kettle and immersion heater on. (we are at the end of a rural line)
Back in the 80's in Helston the TV workshop voltage hit over 280 volts, RNAS Culdrose recorded almost 290 volts, we were kept very busy for a year or so, all those marginal smoothers in the old ITT hybrid tv chassis doing weird and wonderful things after a year or so, all the built in thermal fuses in LV transformer in the then new ITT TV's went O/C ITT spares dept could not keep up with our demand for replacements, lost count of the number of freezers that went pop.
Happy days.
