CPC ring on a radial

[Steve-S]

A great advantage of a final ring circuit is that there is a CPC fed from two ends. If the CPC is broken for any reason the continuity is maintained. So safer for sure. With a radial if the CPC is broken a whole raft of sockets can potentially dangerous. I saw a 4mm radial serving kitchen sockets. I noticed that a CPC wire ran right thru the backboxes not connected to anything in the backbox. So I looked deeper. At the end socket a CPC wire was run back to the CU with the 4mm cable forming a ring. So if the CPC is broken, say at a socket's terminals, there is always a CPC path. Quite responsible I thought. I have only seen this once.
