Shed Supply From Ring Main

PG
A small (7ftx5ft) shed is to be located at the rear of a house. There will be a 2ft gap between the shed and the rear of the house.
The shed is to be used as a utility room, initially, with a tumble drier and freezer It will also have a frost protection heater and lighting.  If we allow a bit of power for future or garden tool use then there could be a max demand of about 18A. There are no other services planned (no water, gas or drainage). The 230V supply is TN-C-S
The house has a lightly loaded RFC on the inside wall by the shed and the proposal is to break into the RFC and loop the RFC through the shed. The RFC is supplied from a Consumer Unit that is located near the front of the house..
Not exactly a standard arrangement, probably wouldn’t even consider it if the shed was a few more yards down the garden but I haven’t managed to locate a statement in the Wiring Regs that precludes this approach. I wouldn’t have thought twice about extending an RFC through a conservatory.
 I wondered if the Forum thought that 465.1 (Emergency Switching) could come into force, say for isolating the shed in the case of a fire but I suppose that the shed isn’t too different from another room?

    2.5 mm SWA out of the back of a socket into a small consumer unit in the shed with a 16 amp MCB in it to feed a 2.5mm radial circuit within the shed for sockets and a switched 3 amp fused connection unit to supply the shed lights.


    Done and dusted.


    Hi Andy, how do you connect an SWA out of the back of a domestic socket and it be available for future inspection?






    if you look at some of the You Tube electricians, the current trend would suggest the armour's cut off at the supply socket, so just the insulated copper cores in their jacket enter the box, with the armour earthed at the load end.
