running power out to shed and garage

[shanie1]

hi , i want to run power out to my shed and garage. the shed is about 3m from the house while the garage is 16m away. my original plan was to just run out 2 separate feeds from the house using swa 2.5mm cable, but now wondering if it would be more advisory to run a slightly larger 4mm or even 6mm cable seperate to each. i dont plan on going mad with sockets in shed and garage but really wanted to sort of future proof it slightly. any comments would be grateful. also the garage consumer unit is going to have a rcd main switch , can i get away using one with 60 ma on it or do i have to use a 30ma, just got a couple of the 60`s lieing around. thanks for any feed back

Other than the Blagdon system which I think is really out of order and should be banned the cost of LABC charges mean that it's just not economic to DIY this type of work.
