I'll confess, for about 2 years I had 3 twin sockets around my garage workbench fed from a DIN rail enclosure I put under one of the original sockets on the ring which was fed from a 30A 3036 fuse. I had a 30mA RCD and 16A MCB in the enclosure. Strictly speaking not allowed, but the characteristics of the B16 in reality are not much different from a 13A plug top fuse. 25% of the time a 110v transformer would take out the B16 though.
There is a certain amount of engineering judgement that needs to be applied here I think. But I don't think anyone is going to suggest that attaching a sub main directly to a ring circuit is good and proper practice. I'd certainly not be happy if one of our chaps installed such an arrangement
