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)...

As you all know, a troll hijacked one of my posts and kept insisting
that omitting a neutral on a pure 240v circuit would cause a fire,
which would invalidate the insurance.
But that brought up the question in my mind, can improper wiring
actually cause a fire?
Yes.
See here for one example:

Ouch! I stopped to read that page, thinking it might have something
interesting or that I hadn't come across, and indeed, it did. The amount
of
misinformation there is large, especially with the assumed theories that
were stated.
I don't doubt your initial experience as I've seen it myself, but ... I
think you exaggerated greatly and unfortunately made a lot of wrong
guesses
about what what and why.
If you'd like some assistance in updating that page so it's accurate
and
usable as an FYI, I'm sure there are people here who would assist you in
that endeavor, myself included. As it stands, it's a badly expressed
example of a bad situation but your understanding of electricity is
obviously lacking and in need of improvement.
Please elucidate. I am actually quite experienced with electricity and
understand home wiring very well, but I was attempting to explain the
issue in a "dumbed-down" way so that it would be clear to anyone
reading it. I haven't looked at that page since I put it up a couple
years ago, but it passed muster with a couple of electrical
contractors who are friends of mine.
If you have corrections I would really like to hear about them. Either
post them here or e-mail me.
Thanks.
