In my flat I've discovered that each end of the two socket ring mains
go back to separate MCBs.

Yes. The current wiring is extremely dangerous and could easily lead to a
fire. You should fix the problem immediately. I think the whole
installation
should be thoroughly tested. With one absolute shocker like that, there
could be many other disturbing irregularities.


does this mean that the circuits are effectively protected at (a chilling)
64A at the moment, or is the effect not quite that simple and liable to be
indeterminate?
