Not a large house, three beds, two reception etc.
Out here in the French countryside 3 phase is common, ERDF will change to single phase but apparently I would have to pay the cost of replacing the overhead cables from the village to our place, believe me that is not going to happen
basically the current setup has one phase to feed upstairs and the water tank heater, one phase for cooker and dishwasher and one phase for original hob and clothes washer, the sockets and lights etc are split by the various rooms depending on power usage.
The kitchen is the only room where all three phases will be in use, one for the cooker and two for the new hob.
The earth is provided through spikes driven into the ground, when we first moved into here there was only one ground earth point and the cable was actually broken (so NO earth), my wife kept getting a small shock whenever she used the washing machine
