oven and hob query

[sijaysee]

hi i got a hob rated at 6600W. A microwave rated at 3600W and a single oven rated at 3600W

Now the micro and the oven manufacturer say that they must not
be fused at 13A or put on a plug.
I think to do with the cleaning cycle which runs at pretty much
full power for 2 hours. Therefore no diversity allowed

Can i run them on 2.5mm radials with 16A mcb to their own cooker switch?

The hob i assume is allowed diversity which i have worked out to be roughly 16 A too.
Now do i put that on 16A mcb or do i disregard the diversity and
assume full load which is about 28A?

That and they will be pulling about 15A each

20A DP switches might be more desirable. Don't know enough about design to say about cable size.

Better to allow for full load imho.

Thanks spark
Yea pretty much what i thought.

The run from the CU is barely 6 ft and in trunkin or similar so
i would imagine 2.5mm will suffice.

And 20A DP switches would be better i agree for the ovens.

I will use a 45 A DP cooker switch for the hob
