Several days ago I came to an old Villa in Vienna soon to be demolished (In fact demolition started yesterday, so nothing of this is left) looking for oak floors. I got permission to take whatever I want, but the floors were rotten. So I only took some vintage light switches (replicas as I found out later)
The main fuse box ahead of the meter was open. It contained two rows of fuses ( in those panels phases/neutrals are gathered in vertical rows, so the line terminals can be linked with brass straps) The upper row contained two 32A fuses and an unfused neutral, the bottom row a single 32 A fuse not linked to the upper ones at all and 2 independent 10A fuses. On the panel door it was printed 220V and 440V.
Obviously this was a supply similar to American ones, that had been later converted to standard 220/380 3 ph by hacking in a 3rd phase. No one I asked has ever heard of this!
