Ring Final Circuit wired in 4 core SWA

[Pete999]

You've got it... If it had been glanded straight into the metalclad sockets and used piranha nuts it would of been better.

When you look at this type of system in the cold light of day regarding the earthing/cpc and ignore the L and N conductors the and the Armour being suitable for use as a cpc, then there isn't much difference from that to a metal conduit install. You don't run a cpc in metallic conduit you fly lead from the earth stud in the box to the earth terminal on the socket face plate, no difference in doing the same with the SWA install is there?

If this was a standard 4mm radial without the addition of an extra help for the live and neutral (in the form of another 2 cores to assist) maybe the collective eyebrows would not be so lifted

Wash your mouth out it is a 13A socket and MUST be a ring final

Never uses two core swa for sockets, but when i use metal clad socket ( am waiting to hear "why") but i alway take the paint off in the inside round the knockout (it reassure me)

So let me get this straight.
If we install conduit, we don't need banjos or piranha nuts, but if we use SWA, we do?

Maybe poor circuit design but the rcbo will provide fault protection.

I think 32B would fit better, and for clarity I'm talking about mcb not items of clothing ...

I'm loving this threads tombola randomness

Should be done on ALL metal enclosures, where conduit or SWA installations, lost count of the number of hours I spent filing coupler ends flat, filing lock nuts, cleaning paint from enclosures, not for reassurance, but for a good contact, a lost practice these days I'm afraid.

When I started out I was told to thread the conduit and use two lock nuts tightened up on to themselves and a female bush on the inside, must admit not done that for years.

I bet you if you put the fittings of today eg couplers bushed glands etc. against ones from past side by side you would notice a huge difference.

More worried about using a single 4 core as a ring

Used to be the norm with 4 core MICC/SWA, of course they don't teach that sort of thing nowadays, shame really.
