If I move into very hypothetical areas, I could possibly see a move to
have residential areas supplied at 50v or less, under the elfen safety
banner. There would also be an advantage to choosing a lower frequency,
which would reduce transmission losses (around 12% at lower voltages).
The flicker effect of a lower frequency could be overcome by mandating
only high frequency fluorescents or all LED lighting.
That's going to be a big cable to my 3kW kettle and heater ;-)
There's something to be said for higher voltage = lower current and a
lower risk of fires.
its about power not current
High current = risk of terminations becoming hot and starting a fire.
High current = larger cables that are more difficult to terminate properly.
