Just remembered this one: You might like to compare the DC to 2-ph AC Inverness conversion with Ranger's post about a DC to 3-ph AC conversion in Vienna. Go
here. TR,
With the way many appliances are now sold in the same model across Europe, I've seen plenty of ranges wired for 3-phase here as well which are starpped L1-L2-L3 for use on our 1-ph residential services.
The elements are still regular 230V types, but wired on different phases to distribute the load.
Are you by any chance thinking of American 240V range elements which would be wired across the two 120V hots?
