I am installing a double oven (20 amps) and a separate hob (32 amps) I want to run a 6mm twin and earth from my consumer unit with a 45amp MCB to a junction box, then run a cable (in 6mm) from the junction box one way to a cooker outlet for the oven and another cable (in 6mm) to another cooker outlet for the hob. Both cooker outlets will have 13 amp sockets.

Would this be OK?

If not would it be OK in 10mm? Or should I just run 2 separate 6mm cables from the fuse board? (I have 2 spare slots left).

I also want to spur of the oven outlet to a 13amp socket to run the dishwasher.

Please advise.

You can of course design circuits for whatever you wish but it's not a good idea to have other appliances on the cooker circuit.
As you appear to be willing to run two cables unnecessarily for the cooking appliances it would be better to run another for the dishwasher and perhaps other things.

Without the dishwasher 4mm² cable throughout and 32A MCB will be satisfactory.
This is allowed for cookers because of 'diversity' as not all the elements are on at the same time.

to a junction box,
Which junction box?
There doesn't need to be one.

Not a good idea. Can you not connect it to the socket circuit?
 
Have a look here. This work would be notifiable due to its location.
Are you saying that because it's in a kitchen? If so, and on the assumption that the OP is in England (not Wales), then not only are you not up-to-date with the regulations but you have also failed to read wiki article to which you have linked.

The junction box is so I can split the supply and run it to 2 independent outlets. The oven is on one wall and the hob is going to be on another.

If I could easily get onto the existing 32 amp ring main I would.

You did not say that but still don't need a junction box.

You did not say that, either.

I apologise for advising how to do it properly.
 
Dear Moderator 9 sorry for "Hijacking" the thread. But as the thread was so old and my question seemed relevant to it and as this is my first go, please accept my apology .

You need something like this:

I'm sure there is a recommended limit of 2 metres from the cook control unit to the appliance though.
Don't forget that your circuit will need to be RCD protected.
Also as this is a new circuit you will need to notify your Local Authority Building Control and pay their fee before you start the work.

I fear I have confused you. The cooker and the hob are in 2 completely different parts of the kitchen and need to be run from their own independent outlets. That is why I want to split the feed from a junction box to them.

The item I have pointed you to is a junction box.
Do you have answers to the other questions/points I and TTC raised on the duplicate post?
Like - have you notified Building Control?
Is your circuit RCD protected?
Why do need a 45A MCB - diversity?
etc etc.
There may be a big bas wolf along later who will point you in the right direction - for once I agree with his comments before he makes them.

I'm inclined to agree, but I would never be brave enough to agree with his comments before he makes them - since they have been known to be such (at least in terms of how they say it, rather than what they say) that I wouldn't want to be in any way associated with them :)
