You mean a 3-wire cable? (i.e. 2 hots and neutral)
I'll dig through my code book later, but standard range and dryer receptacles here have four prongs: 2 hots, neutral, and a ground (bond). Each would need its own circuit though.
EDIT: All I can find on the electric range is a demand factor (for conductor sizing). Nothing on the dryer. The issue of 2-wire or 3-wire feeder would be dictated by the appliance manufacturer, would it not?
