What size cable is supplying the cooker, how long is it and where does it run ?

Normally suggest you follow manufacturers instructions.
We need to know the size of the cable you have and the output of the appliance?

I have consulted google on your behalf and located a 45A Hager RCBO.

the cable should hold 48amps, it runs from behind the cooker in the wall and works it way to the consumer unit on the other end of the house.

output of the appliance is 10.2 kw

distance?
and do you have RCD protection on the circuit?

 

[lees601]

no more then 15 meters

 

[lees601]

yes i do

 

[lees601]

well its r.c.c.b

 

[lees601]

so is the new RCBO typeb compatable with the old mt type b

You have two options then
Either stick in a 40A MCB (I assume your cable is 6mm with ref to 48A)
But doing this will mean it becomes notifiable work.
or stick with what you have, under diversity rules it will do.

but with sticking with the 30 amp fuse wont it just keep tripping when i got the oven going at its max (oven and hob on). may be i think question but what you mean by diversity rule
