Can I spur from a RCD protected ring main socket in the house to supply an RCD 2 way board in the summer house, and would it need to be fused at the socket to a spur in the main house? Thanks Alan.

Why the second RCD in the summer house board?
I believe it needs to be fused to max 13A, as that's all the ring is designed to supply at a single point.

I normally would not put a 2 way board off a spur. What are you hoping to run in the summer house a socket and a light or something a little more substanial.
By having as you propose 2 RCD's is wasting money. The best way to do the install depending on what cable your using and how it is run, would be to have a non RCD protected sub main to an RCD/RCBO board in the summer house. Nothing worse that the RCD in the house tripping and you fumbling back in the dark to reset it.

As for TT its TNCS so no need. The install is a couple of sockets and a couple of lights, also there will be an oil filled rad running from a socket, at max 2kw or 9amp, with the 2 lights about 1amp, if you add the possibility of a lawn mower and strimmers, well do the math. Problem I have is the board is at the front of the house in a mid terrace, and the summer house at the rear end of the garden, about 20 metres, otherwise there is plenty of spare ways to have its own circuit, but no way getting it through without wrecking the place, which would have been the best bet.Only option is the socket at the rear of the house with a fused spur, then 20 metres of 4mm armoured to the summer house, then rcd main switch two way board for circuits inside. Correct me if I`m wrong please as I cant see any other way around it.

If the Ring your spuring off is already RCD protected then it's quite pointless having RCD at the summer house isn't it?? A 13a supply i would say is quite adaquate for yours needs based on what you have stated.
And i doubt if 2 lights is going to draw 1A, unless your going for the bigger halogens...lol!!!

I agree no need to TT I was only joking. I would just fit an ordinary 63amp main switch in your 2way board as it is a complete waste of an rcd. Rcd covering an rcd?
