I would call anything that needs 3-phase to be “industrial”. The number of residences with 3-phase would be in the low hundredths of a percent of homes.

3-phase 230V 16A is standard here. but you can get up to 30A if the wiring allows it. I’ve never seen a house with only 1 or 2-phase.

German 3-phase is at 400V, there is no such thing as 2-phase (you’re probably thinking of split phase 110+110 as in NA). So I’d be practically certain your parents have single phase 230V.

between neutral it’s 230V.Between two phases it’s 400V.
