The earth cable must be multi stranded for safety reasons, I have seen larger than 1mm TPS with solid conductors but earth is multi stranded.
I think multi stranded would be more flexible and create less high resistance joinets than solid conductors.

I know enough to be dangerous
My guess... It's stronger, handles movement better, is harder to break so lasts longer and therefore safer?
Just wondering in any case, came up while talking to a US person. Given that they allow NEMA 1 plugs/sockets and wire nuts and other invitations to suicide, I figured the solid-core thing was just more unsound US electrical practice, but can't find any strong evidence to support this.

We were actually discussing this at work the very afternoon you started the thread.
Ah, and that would be the reason. Thanks!
