EICR Coding - Armour not glanded

[Michaelwgroves]

I wouldn't have done it in the first place.

Why not?

I thought about it for ages but could not think of a better way to get SWA through back of a surface mount CU. I'm always interested to hear alternative ideas as I'm sure I'll get this scenario again. The only way I've found to get around this was flush mount CU with gland, but if this is not possible I really don't know a better way ?

I suspect the manufactures instructions for the gland is not to leave it floating adrift from any enclosure, I would C3 that on an EICR.

I know it's a bit unorthodox, but think about it for a moment, what's wrong with it?

I don't need to think about it is "ad hoc" and not in compliance with manufacturers instructions.

I checked both Niglon and SWA Online and can't find manufacturers instructions. I chose these as this is what is in my tool box. Also no instructions come with these. The only thing on bag is size chart.
I then done a google search and found these guys, their instructions don't mention an enclosure, it just shows how to terminate SWA into their gland.

So I don't see any issue?

i'd maybe add lack of strain relief on the termination too.
do you mean pre-amendment 3? what changed then?
EDIT: ah i see westward's post we're talking bout the rcd protection

So assuming you have opted for swa to avoid additional rcd protection and seeing as you have not maintained this earthed containment to the enclosure of the consumer unit there is a part of this cable contained in the wall cavity without additional rcd protection.

I agree with FI, I wired a HMO with SWA from Switch Fuse (Metal Wylex 110M) properly glanded in main intake cupboard to CU in flat. Terminating SWA on CU would be ugly with all other wires entering from rear. I spent weeks deliberating solution.
Old spark suggested terminating behind CU with floating gland and bringing flying earth lead into CU.
I didn't like the idea to begin with, but could not see anything technically wrong.
At the Intake cupboard it is clearly visible, the EIC details it's SWA.
Maybe you have a similar scenario?

Floating glands are a bodge, why not just fit the gland into the flush box behind the CU?

I thought about it for ages but could not think of a better way to get SWA through back of a surface mount CU.

If it's a solid wall terminate he SWA into the flush box you fix behind the CU or a galvanised terminal box behind the CU.

For a stud wall you can again use a terminal box or fit the gland to a galvanised elbow which then fits to the back of the CU with a bush.

It doesn't my comply with 134.1.1 or 134.1.4, it is not good workmanship nor is it of proper construction.
