I have not confused anything. The idea is that powerful applliences require more copper and bigger gauges for lower voltages (not linear). And we have more if them. So by upping the voltage we can save on the wiring.
In eu you don't have to think where to plug 2.5 kw space heater. Any outlet is good enough. In the US you have to. And with home appliances actually becoming bigger and more powerful I think that even the EU baseline will become too constraining eventually. Since usually there are limitation on the gauges that are ran from the main breaker to the sub-breakers (don't know english electric jargon)
Where I live I have a wire that can hold I think 40 amps in the wall from the main breaker to the board where the small breakers terminate the different home circuts. If I want to upgrade it is dig baby dig. 6 floors.
