New T&E cable...

[Initforthemoney]

Seen a couple of videos with Doncaster cables now producuing a T&E with the CPC already sleeved so no need to fit our own.

I also read somewhere that this will soon become the norm and will have to be installed to comply with the regs instead of the regular cable.

Any truth in that?

Flat twin cable with sheathed CPC.

I see they're introducing a new type of flat twin cable with a sheathed CPC. In my location there's no requirement to sleeve CPC/bonding conductors and you never see it done. We just install and arrange wiring in enclosures or DB's in such a way that there's no realistic chance of the...

Thanks, but i was wondering if there was a reg that was being introduced stipulating that it should be sleeved throughout its length?

 

[nicebutdim]

It would seem odd to think that a new reg would be introduced, mandating a cable only recently introduced by a single manufacturer, shortly after a recent amendment to the current edition of wiring regulations.

They can bring it in as a new reg only if they change the core colours back to the old ones.

They can bring it in as a new reg only if they change the core colours back to the old ones.

....and reintroduce lead external protection?
Then they can do away with the cpc core all together!

Funny thing is…. I was using this in Europe twenty years ago….

The only reason we sleeve the CPC is for identification so as far as I’m concerned this is a pointless exercise except if you happen to be a price job house basher and see it as yet another 5secs off the time of your already shoddy wiring.

(And before anybody cries that it’s about insulation, consider the simple fact of conduit used as cpc).

Where did you read it?

Furthermore a representative of Doncaster Cables themselves has also stated that it is not rated as insulation, but is merely there as identification as you state.

An Aprils fool joke created by Efixx

BS12721:2024 residential cable standard. This standard will ensure safer and more efficient wiring for your home. However, it also means that the trusty BS6004 cable will be phased out and cannot be used for new home construction or rewiring starting in April 2024

Since 2017 this has been a requirement in the Republic of Ireland. In addition to an insulated earth conductor it must be sized the same as the phase conductors.

New Twin & Earth Wiring Rules

Since Sep 5th 2017 all electrical installers and contractors in Ireland have been required to use the new IS201-4 twin and earth insulated electrical cable.

No we aren't!
It's people posting things like that online that are going to cause these rumours to spread.

Indeed. And in more recent years it must also be certified Dca, -s2, d2, a2 or higher. (Essentially LS0H.)

Sorry. I meant that C3 remark as a joke.
I’ll use more smilies next time to make it obvious
