New oven wire correct size??

We're thinking about buying a new convection oven to replace our old one. We have 10-3 G NMB 600v wire with 2 30amp breakers currently to our present oven. The new oven states it needs 240v with 40amp breaker with 6.9KW @ 240v. Is the wire we have big enough to handle the new oven if I the breakers were changed to 40amp? I don't want to over heat the wire and cause a fire. Also when it says it needs a 40amp breaker do they mean 2 40amp breakers or 2 20amp breakers that equal 40amps.Don't worry I do plan to hire an electician to do whatever work I need done.
