Got me curious when you mentioned that earlier, I'm in Baltimore at the
moment fixing up my sisters new house, and the electrician told me they do
NOT use mutiphase power systems in this area for houses (we are having a sub
panel put in)..

From what I was told (that may or may not apply to you/make sense), Theye
bring 3 wires in off the pole, two hot's and one neutral. The two hots are
called legs, and a hot to neutral is 120V, and hot to hot is 240V (two legs,
no neutral) .. The powerline networking stuff works/multiplexes on the
neutral, so only 120v stuff will work (since they share the neutral), but
not the 240V since there is no neutral... However, it is very rare for any
240 plugs in the house (usually for things like range/oven/dryer/big ac/etc)

There are some commercial places that have two phases (restaurants,
laudries, service station (for the hydraulic hoist etc) etc), and some
humongous mills that use a third phase for things like a 50 ton hydraulic
press, or rollers for 100 ton hot metal slab mover.. Doubtful it would ever
be in a home though...

So I have to wonder, where do you live.. Is it feasible that you have three
wires/two hots/single phase? In that case it will work fine... Maybe they
just call it somnething else in your neck of the woods? No clue (and the
electrician guy had no clue) what a 3 PHASE system could possibly be.....
