bad connection. Radials suffer much worse from them than rings.

A ring has more connections so a bad one is more likely.

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

And that is good because?


The effects are different.

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.

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.

In practice you need to have two bad connections for the ring
to stop working and that is no worse than a spur failing with one.
