The voltage started at 220 way before the 60s, and then increased incrementally over the years, until standardizing at 240V. I don't know when the first bump past 220 happened exactly, and it may not have been simultaneous in all areas. I gather the reason for the standardization was to stop the creep and pick a voltage to stick with for everyone. |
