Nilkant's answer with regard to transformer size is wrong.
For a given KVA rating of a transformer lower voltage would
require larger conductor cross section (current being
inversely proportional to voltage for a given power).
Therefore, larger conductor size will result in larger size
of transformer. As for the main question, I THINK Americans
use 110 Volts (instead of 230V)as rated voltage for end
users because lower voltage means higher safety factor for
consumers. Well it comes with a price! Their system will be
more expensive since all the wires of their home appliances
and distribution conductors will be larger in size. MAY BE
they are rich and can afford it!!!
