hello,
you can start by using 240V like all decent people (read, in the rest of the
world (Japan except)) and significantly reduce your risk (with or without a
neutral or ground).
the main reason is ohm's law (U=RI) coupled with resistance law J=RIČ and
power law W=UI
ie: if you divide the Voltage on a circuit by 2, you will need to increase
your intensity by 2 and therefore, the energy wated in the conductors (read
heat) (of fixed resistance) will multiply by 4.
so, for the same 'product' with the same output power, your cables will heat
4 times more in 120V than in 240...
so, 240 is much safter than 120V (at least when it comes to burning down
your house)...

Nice thought - I'll have all the makers of electrical equipment in the
U.S. change immediately...
