External RCD/sockets

Steve Mc: 
 

From a house ring main can an external rcd socket be used as a fused spur to a small consumer unit in a garage less than 10m away using 2.5 buried protected cable?  (2 LED strip lights and 4 double sockets in the garage)

So essentially a 13 Amp plug will be plugged into  an external (hopefully weatherproof) outdoor R.C.D. socket to power up your garage.

The fused 13 Amp plug will provide overcurrent protection and the R.C.D. will provide additional protection against shock.

Why not do that, with suitable mechanical protection of the cable that runs underground to the garage. It is just an extension lead.

The regs. refer to a ring in a house supplying 13 Amp sockets etc. as a ring final circuit, not a ring main.

You might struggle to connect your 2.5mm2 T&E cable into a 13 Amp plug.

P.S. I was typing this when you were posting your image.
