Do countries with 230v electricity have any sort of similar systems to the 120/240v system in North America?
edited to add: I am asking about residential service. We do not need to get into commercial service, three phase etc.
Generally the power lines run to the residence are also 3 Phase. Generally
only one phase makes it to the home, but on request, they offer multiple
phases in many countries. Rare, but not impossible.
I can't think of anything for residential use that uses a power feed
over 220-250volts.
