Sorry you cant do this 2.5mm is limited to a 16a mcb !

Wire the appliances on the ring using 20A dp switches above each appliance
with a socket below, the Hood should be on a switched fused spur (3Amp fuse)
and the cooker in 6mm with a 45A DP switch within 2mtrs of Hob

Similarly sorry. Come what may there will be no switches above the
surface! In one instance (the W/M) that is for aesthetic reasons, in
the other it is because the hob and sink are either above or below the
units (the D/W and hood). Oh, and it is a gas hob (as mentioned in the
initial thread) so we're only worrying about ignition power. The ovens
are on the other side of the room with their own feed.

Please keep the comments coming, being able to argue the toss with bods
who understand the problem is sooo much more satisfying than trying to
discuss it with SWMBO.
