Power to Garage

[5parky]

Hi
Can anyone help please.I am running power to my shed which is about 28m away from consumer unit.It's about 11m in the house & then 17m outside in the garden.Iam planning to use twin & earth in a trunking inside house & swa cable clipped to fence outside.Just wondering if 4mm2 is enough inside or i have to use 6mm2.Also for outside is 4mm2 good enough or i can get away with 2.5mm2.I'll be using rcd unit in garage with b6(lights),b16(sockets) & will be using light & tumble dryer(not bought yet) only at the moment in the garage.Also do i need 16a/20a breaker rcd protected at main consumer unit.finally do i need separate earth rod for the garage or can it be all connected to main earthing terminal

Please Advise ............ Thanks in Advance

imo i would use at least a 6mm all the way to allow for future use. i believe that you will not need a separate earth rod!
