Hi Damon, this differs with Power suppliers, I live in the suburbs of
Central Louisiana and we"re supplied by a Rural Electric Co. They deliver 3
wire 220 to homes, The 3rd wire is a large unshielded wire. Most Main fuse
boxes use both sides to gnd
to balance the load. If 220 is needed then it is delivered from both sides
and there is a neutral (gnd) also used. the receptacles have different
forms depending on how much current is demanded. My neighbor had a large
workshop where he welded among other things and he had a special line run to
supply him with 3 phase current for large motors, etc. Hope this clears some
of the confusion about USA power, European is different depending on which
country U visit. Wal-Mart supplies a travel kit with adaptors for all
counties U might visit.
