I am sorry but you are mistaken, in the USA the lines are actually 250 volt line to line, 125v line to neutral, (which is a center tap on the transformer coil) Code allows up to a 5% voltage drop to the meter and another 5% allowance from the meter to the destination, The transmission lines are around 9,000 volts to get out to the neighborhoods (tho some areas may range from 4,500 to 12,000 volts)
