multi strand 2.5mm T&E - is it OK to use?

[Sintra]

Hi, I've been working in a relatively new house (approx 5 years old) and the kitchen ring is wired with 2.5mm, twin and earth in which both the line and protective conductors are multistranded.

Is this OK to use? I've never come across it on 2.5mm cable and they have nuisance tripping on this circuit, just wondered if it was in common useage as I've never seen it before.

Thanks

He says in which both the line and protective conductors are multistranded.

i read it as both line conductors multi stranded. 2nd read says i misread it.

if you read th OP , he says the phase conductors are stranded, not the cpc.

If you read the OP properly i think he does mention the CPC is stranded.

I've never seen this type of cable either. Isn't it as simple as look for the 'kite mark' or similar (underwriters laboratory etc) approval/conformance stamped on the cable.

You must have posted while I was doing so fella! You had me doubting myself as it's been a long old day, sounds like I'm not the only one either! Lol Hope the winking smile provided the right level of wit to my post without sounding like I was being an internet ****, haven't been here long enough to start trolling and upsetting the regulars!

I've just be checking with Draka and FS cables it seems 2.5 mmsq T&E with stranded conductor is available in harmonized colours, Table 9 of BS 6004 specifies alternative conductor (class 2) options for 1.5 mmsq and 2.5 mmsq stranded conductor twin and earth cable. It's not as common as the solid conductor versions but according to the manufacturers it is available off the shelf.

I wonder how many of your wholesalers will have it in stock?? You'll have to see, next time your down there!! haha!!!

Hi

Just seen your post. Although it is an old one I wouldlike to comment on your question in case someone else is looking.
I have only been in this Country since 1990, having originated from NewZealand. In New Zealand everyone uses stranded twin and earth and the earth isalso sleeved. Solid is not used because it is not flexible enough, takes longerto get straight and is not so easily twisted together.
It would seem that the solid here in the UK is used because people do notnecessarily know stranded is available, which it is, in 1.5 and 2.5 twin andearth. I never use solid as I feel it is inferior and a real sod to use.
If people started asking for stranded twin and earth instead of solid then the supplierswould have to make it easier to get. RS have started selling it, by the way.
I find it hard to understand why every other cable youbuy has a sleeved earth yet twin and earth does not. The cost difference issurely minimal.
If you get the chance to buy stranded then do so. Youwill never go back to solid.

We used to have stranded, pag. Personally, I hate solid core and love working with the old imperial stuff. I bet the accountants who decided to switch us over to solid-core never had to work with it...

I have purchased stranded 1.5mm and 2.5mm twin and earthfrom the wholesalers, but I had to wait for it, as it was not off the shelf.Looking through the RS catalogue recently it looks as though they do it,although I have not yet confirmed this.
