People only see what their outlet provides. If you ask someone about the european voltage, they'll probably say "220-230V", not " 3-phase 400V".
Well, I could be wrong here, but I don't think I've ever seen a European outlet that did more than the 220-230v...
We're not talking about three phase setups here... Residential in the USA is commonly 120/240. Not just 120.
If we're going to talk 3-phase comparisons... then you'll see all number of setups, but the most common would be 120/208, where 3 phases are wye tapped.
But in a typical USA home you can and will find 240 volt outlets for ranges, stoves, dryers, etc... We have outlets that provide 240.
There are special 3-phase connectors, but usually only in the kitchen (for an electric range)
