I'm not a power systems engineer, but it could be that changing the supply
voltage would be a matter of changing taps on a transformer.
As for flag day - I remember as a kid when there was a changeover to 60Hz
in the hydro system. (Was it 20Hz before that? Something much lower.)
Anyway, every electric motor in the house had to be changed. Must have
cost a fortune.
