Firstly, I'm going to get a sparks in to do this work so he'll be the final say on the design but I'm a long way off getting him in to design the entire outside garden electrics (lights, Hot Tub, external power, ancillary buildings etc).
I want power to an outbuilding and whilst it's still under construction I thought it might be wise to put in the power cables for the sockets and the light.
For the light I thought a single 1.5mm twin core with earth that runs from the ceiling to the switch then do I put in a 2.5mm twin core with earth running from the switch to wherever the fusebox would be?
Same with the power sockets - would it be a 2.5mm length from the fusebox to the first socket, then another from that to a further socket etc until the last cable comes back to the fusebox area?
