I noted recently several refs by USA users asking about 240 volt ac power
plugs etc.
Now I have never even been to a 110v country - possibly only USA ? -
and
I can see a degree of (shock) safety offered with that system, but I can
hardly imagine the mass of copper required to carry possibly
Most American homes have 240V at the entrance (circuit breaker or
distribution) panel. But, since most US electrical appliances and lamps have
been 120V for(almost)ever, the electrical system is split with 120V single
