Yes, but a ring continues to work fine when a bad connection happens.

And that is good because?

Just why are you rising to the bait?





And rings handle a single bad connection fine.

But they dont, they can overload because they are no longer a ring.
The average user can't know if its faulty or if they are overloading it
because of that fault.
Just because something continues to work when faulty doesn't mean its a
good thing, in the majority of cases you want to know its gone faulty.
If you want a ring to continue working with the fault you need different
cable or a different breaker.

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.



It would be nice if something told you it had broken so you can get it
fixed, I used to do this with fault tolerant computer systems all the
time, they were useless if you didn't fix them before the next fault
took them down.
