Interesting about Italian wiring. I've never been to Italy, so I had no idea what techniques they used. All I knew was the old-style Italian outlets with three round pins in line, ground on the center and reversible. Didn't they have ones with a slightly wider pin spacing for 16A and a the smaller version for 10A?

Single-phase 20A service must be very limiting. I thought the 3-ph at 15A per phase in some French homes was bad, but a max. total load of under 5kW must take some beating. I guess gas ranges must be popular in Italy.

Assuming that some houses have electric heating, do they have the heating cut-off contactors found in some French homes?

By the way, how are you getting used to your new currency? I'll have to adapt to to the Euro when I head for France shortly.
