A ring has more connections so a bad one is more likely.
The effects are different.

and if there is a break in a radial circuit it is very obvious. Not so

A break in the earth circuit in a radial is going to be obvious? Maybe
only when it kills you.

The ECC is the thinnest wire so most likely to break. With a ring there
are two. Unlike a radial.


I wouldn't make such statements without evidence.
The thin wire is more flexible so wont break so easy if it suffers
movement.

Every time I have found a discontinuity in a CPC, its been at a
termination. Typically either down to being lost in a mass of
connections and improperly sized sleeving such that one wire was never
actually pushed into the terminal, or, due to being over tightened such
that it fractured at the terminal.

Inspections probably find more earth faults because they show up in
tests while none working sockets get fixed before the tests.

True... although I rarely find a completely non working socket (and last
time I did, it was actually a non working MCB!)
