what sizes are the ovens in watts, no such thing as 30amp cable.
You measure cable by it's Cross Sectional Area in mm.
Factors are then calculated in to determine what current it can carry.
So three/four questions
1,What power in watts is each oven?
2,What size is the CSA of your cable in mm, this may be found on the plastic sheath of cable?
3, what size and type is the protective device(fuse/breaker) connected to this cable?
and then we will try our best to help.

10mm should be plenty big enough.
You have total output value of 2400x2 = 4.8kW
So if the if you intend to run the cooker of 45Amp cooker switch/isolator that's okay.
The circuit will need a 20Amp MCB as that will be enough to power your cookers.
If the cooker isolator was a socket outlet on it, the breaker size will need to be increased to 25Amp MCB
If both cookers are being controlled by the one isolator this needs to be installed so it will isolate both appliance and not just the one.
This isolator should be installed within a minimum distance of 2 meters from the appliances and no closer tham 300mm for any hob.
What you intend to do will need to comply to part p of building regulations and will need notifying to building controls either by you if your DIYing or by your electrician either by self-cert or application.
