I suddenly remembered a neighbour who kind of might have earned the Darwin
award, as his wife seemed liable to kill him when the whole house was cut
off. This was an old house with just circuit breakers for sockets and
lights.
What he had done many years earlier is taken a pvc three core cable along
a fence, up a pole and over a concrete area to a post on his shed, then down
to the shed.
His major mistake was to situate a garden incinerator just below the cable
and light it full of garden waste and go indoors to what the tv.
I'm sure you can guess that a half an hour later, all his sockets went off
with a bang as the pvc melted.
Ahem.

Hi.
Just thinking on while I'm rewiring the kitchen I may as well lay down
the cable to reach the shed in the back yard.
I used 10m of 6mm cable to reach the cooker connection unit so I'll need
only 20m maximum to reach a box in my shed.

1st question : It will be a separate breaker in the CU so white size
cable to use 6, 4 or 2.5 ?

That all rather depends on what load you need it to support... having said
that, cable is relatively cheap, and access, opportunity, and time and
effort might be harder to come by later, so larger than you need right now
may save lots of hassle later.

Have a read though:

There is a section on submain design and cable choice.
