In the US, real three phase is only in industrial systems. I've never seen it in a house. In US homes, they run 240 AC in, and split it for most of the outlets, lights, etc. So you run 240/2 or 120V for domestic stuff, with 240 V only for heavy appliances like clothes dryers, electric stoves, and water heaters. As you say, with twice the voltage, the wires only carry half the current for the same power. -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
