Before you carry on, please find out about Split concentric.

A/ the outer cores are not armours they a conductors in there own right.
B/ the DNO’s use concentric NOT split concentric.
C/ it is treated as Lenny pointed out just the same as T+E

It’s nice stuff to work with. IF YOU KNOW WHAT YOUR DOING!

They use both Tony, depending on what earthing system they are providing/replacing
About 10 years ago, in one of mums neighbours house, a workman drilled thru the DNO's supply cable that was imbedded in the hall wall, going to one of those council metal service boxes in the hall. When they replaced the cable (TN-S) it was with a split concentric cable. changed the cut-out too....

Hey, sorry I stand corrected. But in all honesty I’ve never seen DNO’s use split concentric.

But we live and learn. When I’ve learnt it all, some t**t will be screwing the lid down on the box.

I’ll go and sit in the corner with my dunces cap on for now.
