Typical home installation here in Ireland would be 230V 50Hz and depending on the age of the installation and the size of the home the main fuse will be either rated at:

50 amps (very old)
63 amps (old)
80 amps (modern)
or
100 amps (modern)

63amp supplies are pretty widespread though.

3 phase is rare in homes, although it does exist. You'd need a specific reason to have it e.g. a workshop or, sometimes for spreading the load on large electric heating systems (rare!)

TN-C-S is the preferred system and the most common by far, although TT exists, but it's typically single phase and supplied with a neutral, the neutral is just not connected to earth locally and would not be considered safe to bond to. Typically, those kinds of supplies tend to be found in rural areas or sometimes in old overhead urban systems.

I've noticed a lot of newer ovens meant to be installed anywhere in Europe accept various supplies i.e. simple single phase + neutral or various 3-phase configurations. In reality the oven elements only run on 230V regardless of which way you connect them up they don't use 400V at all, just split the load over the phases available
