Nor me, but later in the week, perhaps - by which time some of the unknowns in your list above may be filled-in.
It would be particularly useful to have an answer to "device protecting SWA to shed not known (type, rating)" (i.e. the device at the house end) and also to know what sort of activities are to be carried out in the outhouse/shed - IOW what is the electricity supply actually required /for/?
I could have made this easier I see :)
Protected by a 30ma rcd (?)
Its actually fed off a 30 amp mcb (?) on the house consumer unit
Yup
Metal cu with old fashioned wired fuses
2 rcd sockets for outside stuff 2 sockets for beer fridge and freezer Lights inside shed (shed only 15' x 8' internally)Ah gwan :)
And thank you very much for the assistance rendered so far. The worrying bit is the advice I've had from some 'proper' sparks..........(NOI)
Lighting. Fridge and freezer. RCD sockets for anything from radio through concrete mixer up to 3kw angle grinder. Possibly all at the same time :)
As I said I hadn't referred to a cable chart so I bow to your correction. Does the fact that your sizes are for XLPE affect the size over PVC?
Er, the literal answer to that is clearly "no" - but the o/d of the PVC insulated stuff is quite a bit larger:
