Vin,
When you mention 240v, is a full 240v typically used, or is only one leg used?
We run 220v. Our electric range runs on it, my compresser, ect.
Most lights around the house, the blender, mixer, vegetable steamer ect, run on 110v. The 110 is one leg of the 220V.
I would guess the same is true Down Under?
