The Italians will happily put you on a 15 A single phase supply regardless of the size of your house! And yes, they've got serious voltage drop issues there! I remember my parents' Sony stereo playing cassettes slower and slower and finally shutting off!
You wouldn't believe with how little power you can actually get by!
A German spark who eventually moved to Italy told me the story of the whole new housing estate. He ran something like 95 mm2 because the line was longish. Then came ENEL and installed a full kilometre of 6 mm2 overhead wire! He was a bit peeved I'd say
15 years ago I spent an exchange week in a 1970-ish flat in Torino. One evening my host mom had dinner in the oven and my host sister went to take a shower while I was sitting in my bedroom reading. Suddenly the whole place went dark because the combination of electric oven and water heater were too much for the 15 A mains! There were no individual MCBs or fuses, just a main 15 A RCBO built into the meter base!
