Ring main in 4Core SWA

[TJC1]

Evening all

Has anyone ever wired a ring main in 4Core SWA and used the sheath as an earth?

Just looking at wiring some sockets in an industrial unit and wondering whether to do it that way or do a 4mm radial

Because if I need a 30a supply I just pull in a 4mm radial , why bother with a ring...

A 30A supply for what? sockets, a stand alone machine? I'm sorry for the brevity of my answer, I can't see your profile, consequently unable to expand my answer, as I'm unsure of your background.

I cant see any reason to pull in 6 x 2.5mm cables into a conduit tube to form a 30/32a ring circuit

Why not just pull in 3 x 4mm singles to achieve the same result

Or am I missing something ?

I tend to agree Mate, but it depends on what is specified by the designer isn't it, if a Ring final is asked for you put a ring in, but if you are the designer and feel a Radial is the best option then yes you are correct. The initial question was, I believe has anyone wired a RFC in 4 core SWA, The analogy of wiring in conduit was to distinguish the different methodology

If you use 4 core SWA two of the conductors would have to be crimped/wago or terminated behind each socket.
