That's curious, the wikipedia info looks just like some types of American 220/240V outlets with two hot legs of the three-phase distribution network wired to each residential receptacle and an earth ground, but this wiring diagram has me puzzled. I guess I'm being sloppy with terminology, there were two-phase systems. Two of three legs in a three phase grid isn't really the same thing as two-phase I guess, but
YOWCH!!!!! 8-o
I take it you don't have any of our ridiculous "single-phase," capacitor start, induction motor silliness down under? Or do you? :?: Is there much call for the use of universal motors there?

Here in the US, single dwelling units aren't provided with all three legs needed to run three-phase motors, which are the least expensive and most efficient available. So we end up running phase converters, big three-phase alternators run from even larger 220V (two of the three available phases) to run things like big Radial Arm Saws, Table Saws or the big (60HP) milling head an acquaintance is installing. None of the electricians he asked were willing to set up the necessary equipment for running his $100,000.00 milling machine for him, they took one look at that thing and didn't want to take on the responsibility . . . so he's doing it himself.
Folks in industrial spaces routinely have three-phase power as do some multiple dwelling units and mixed light industrial/residential units. One of the previous tenants in my last shop had snagged the third leg from the landlord's basement power to run the three-phase plastic welder he used in his jewelry making business. [}

Back on topic:
Now they're calling it the
PowerKey Classic! Does anyone want any info about the
PowerKey Pro? I'll try to find the PowerKey Remote, the info on it seems to be AWOL . . .
. . . :lol: but who's got a landline
and ADB any more anyway!
