EICR Coding - Armour not glanded

[westward10]

You need to make your own decision based on circumstances, BS7671 states a minimum C3 entry.

 

[Upton Sparks]

Just out of curiosity why would you give a non RCD'd circuit covering a Twin and earth buried cable as a C3?
is this not potential dangerous ?

C3 because it complied at the time of installation. just non-compliant with current regs.

I agree complete with with the sentiment that buried cables in prescribe cable zones are not that dangerous........ we have the Darwin awards for a reason!

Its complete subjective I don't think there a right or wrong answer.

But I have very few home owner's ask for an EICR, mainly when they're buying a house, and in that circumstance I would agree a C3,
and most like recommend a new CU for there Piece of there piece of mind.

Landlords and commercial customer asking for an EICR,

I would call it a C2, as these guys are doing this more for commercial, legal protection and insurance purpose, so in this instance cover your arse!

If its a landlord, he can spend the money and make the installation as safe as possible.

If its an employer, he can spend the money and make the installation as safe as possible.

If its a home owner, he can do what he like's. its very unlike he'll take me to court.

I went with the advice of FI in this instance, as I can't guarantee it's SWA but all evidence suggests it is. I'm no longer working for my uncle, I saved a copy of the report as I left it, so if he decides to change it to a C3 then that's on him, but I have the report showing exactly what I classified it as.

Left uncle on good terms, just want to cover my backside as you never know what's around the corner.

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?

 

[suffolkspark]

The inner isnt propper insulation though is it? And you have an inaccessible joint then (the earth flocknut flylead arrangement)

 

[Michaelwgroves]

Work was prior to 17th edition part 3, otherwise you have a good point.
Latest HMO I did I used flush Wylex CU which enabled me to terminate directly on CU.

 

[hightower]

You got a link to these 'floating glands'or was it something you fabricated? (Or do you literally mean a gland that is just floating behind)

 

[telectrix]

push comes to shove, could gland into a wiska box or galv. conduit box, then link up to CU with appropriate cable, ensuring that the armour is earthed, of course.

Literally just a gland that floats.

Although SuffolkSpark has a valid point about inaccessible joint. Could not do it today unless you had an access panel.

 

[westward10]

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

 

[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 ?

 

[westward10]

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.

 

[Michaelwgroves]

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

 

[westward10]

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

 

[Michaelwgroves]

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?
