Twin&earth and SWA installed loose on floor

[StigOfTheDump]

Hi All,
The contractor working for Magnet Kitchens at my brother's house has run the sockets ring in 2.5 T&E, plus an SWA for the cooker supply, by laying these cables on the floor under the units.
I'm fairly sure this isn't acceptable - at least these cables should be clipped up against the wall (shouldn't they?).
We had actually expected the cables to be chased into the wall before the units were fitted, but they've done the electricals and plumbing after the fitout...
Any thoughts or comments? Many thanks.

It doesn't look like SWA to me either. Can anyone identify it?

Looks like NYY-J cable to me. A 3c 2.5 mm is 11.3mm, and 4mm is 13.1mm OD according to some links I've googled, with a 25A & 34A respectively.

PS I'm right though, ain't I

Thank you Midwest. I agree, it looks like NYY-J cable, based on a quick google image search of that term. Must confess I'd never heard of the stuff, but that does explain the white inner jacket, no SWA glands, tight bend radii and small diameter.
So much for using armoured cable for the outdoor cable run then!

To be fair it probably doesn't need SWA, just something UV resistant.

NYY-J cable is designed to be used outdoors, in various circumstances.

OP if your brothers not happy with the install. Put together a letter or an email of your concerns, and send it to the sales team, with whom you've made your purchase.

Ask them to address these matters. If that cable has a securing stuffing gland at one end, why hasn't it got one at the other, for example. The inner core should not be exposed.

It looks rushed in. you can easily wire PVC/PVC T & E through the voids and keep it neat. I think it could be 4.0mm 3 core SWA (I have had the jacket in SWA white) The SWA should be earthed at least one end SWA should be made off in some sort of compression gland.

I'm used to cooker circuits in 6mm+, so let's hope it's not 2.5 ...

 

[Toneyz]

The CU end of the SWA has been glanded - but with a stuffing gland:

Now I've received the pictures, I cannot identify what the 'allegedly SWA' cable really is - can anyone identify it from the image below?

So the SWA is not earthed.

So the SWA is not earthed.

What if it is NYY-J cable.

 

[Toneyz]

What if it is NYY-J cable.

Sorry Midwest never used or seen it as far as I know.

We've now firmly established that the conductors are 2.5 sqmm. The spec is not embossed on the cable jacket where we'd expect to find it, but each of the 7 strands of copper in each of the 3 cores is around 0.7 mm in diameter, so πr² X 7 gives us 2.5 sqmm

Only person that actually clarify what spec this cable is, is the installer.
