The choice of 117 VAC RMS nominal in the US is more of a political
choice than a choice of technical merit.  In the early days of
development of power distribution in the US, there was bitter
rivalry between Edison, a proponent of of DC generation and
distribution, and Westinghouse, an AC generation proponent.  Edison's
company spread fear stories about the supposed inherent danger of
AC current versus DC.

Of course, it makes sense to keep the voltage in the distribution
system at as high a potential as possible to reduce energy losses
to resistive heating in the wire.  Note that out-of-phase current
may deliver no power to the load, but does cause heating loss in
the wire carring the current. Energy loss is greater for low
voltage distribution systems.

Re: the previous posting:  a lower AWG number on wire denotes a
larger corss sectional area.
