Hi, I'm just planning ahead whilst I'm redecorating and installing hardwood floors e.t.c. and want to run a cable 10 metres from my existing house's meter and CU between the upstairs floor joists to the other side of the house (where there is currently a garage which I'm planning on turning into an extension with bedroom, bathroom and bigger garage at a later date. This will allow an electrician to install a separate localised CU for the extension in the future. The new CU will definitely NOT need to supply any heavy loads (electric showers, heaters e.t.c.) just a few socket radials, lighting e.t.c. maybe a garage door opener. The house's supply is TN-S with 25mm tails. Will it be suitable to run 10mm T&E clipped to the joists to supply this CU, or is a larger earth CPC required? (The plumbing is already bonded with 16mm cable to the house CU, and there will be no extraneous metal parts to the timber frame structure). Will this be able to be connected to a 60a switch fuse by the meter, or will it require RCD protection because T&E isn't mechanically protected? It would be virtually impossible to physically run SWA as I need a bit of flexibility to get round the corners, through holes in joists e.t.c. so T&E is preferred.
