In a prior life (before college) I was a marine electrician.  The ships
I worked on had "two phase" 110V lines.  55V on neutral, and 55V on hot.
Again this is for the above saftey reason.  The only problem with this
is the modifications that needed to be made to convert commercial
electrical equipment (radios, coffee pots, etc.) safe (well, actually
just a bit more sailor proof :-}).
