I did wonder whether the cable is overspecified to allow for this. There
must be loads of ring mains with breaks or dodgy connections, but the
number of electrical fires is fairly small.


Most ring circuits are underloaded. If there is a bad connection at a socket
then the socket usually packs up before the wiring (there may be some small
localised wire damage).

The minimum Iz of the cable for a ring is 20A. That's the maximum a double
socket can supply without burning out.
