Just out of curiosity since I've just ripped it out ...
The house I've bought has a stair lift, and the installer tapped of a supply from the back of a socket on the ring main for it. So next to the socket is an RCD in a surface box, and then an FCU, finally some flex clipped around the place till it reaches the stairlift.
The connections from ring to RCD, and RCD to FCU were done in stranded - a couple of bits cut from the flex I'd guess. Not sure of the size. I suppose this should be OK since the chance of a short in the 6" of wire between the ring main and fuse is pretty slim. I was also not surprised to see bare cores passed through a round knockout in the plaster box with not attempt to protect them from the sharp edge
But what did surprise me was that they didn't bother connecting an earth. The stair lift is metal, it's got a 3 core flex connecting it, but no earth between the FCU and ring main. I can only thing that whoever bodged this must have thought that an earth is redundant when an RCD is fitted
