Darn, glad I don't live there. If I did, I'd say screw it and run all my HV
stuff off a generator (have to for the 25kw+ stuff or 3-phase anyway) or
move to another country. Don't  know what the reasoning is for the 50v
thing, stepping it back up is just as "unsafe" as if it were straight from
the plug with 120A behind it. I personally run all my stuff (<25 kw)
straight from the 240v mains in the basement, by the time the 100A main
breaker pops the volts drop to about 215-220 and dims the entire
neighborhood (partly due to the Cinergy gas and power penny pinching and
hooking entire blocks to paralleled  25-50 kva pigs spaced 2 blocks apart
rather than every house/building having it's own pig). Still, in Cincinnati
I get more complaints for noise than brownouts (none actually for those
here). Small towns are less forgiving since the entire town and surrounding
area is affected. Ask me how I know ;).
