So is triple brown & earth actually available in the 26 counties?Under ETCI Rules?
No - it is prohibited.

I have never seen it, but then there wouldn't be any reason for it.So is triple brown & earth actually available in the 26 counties?Under ETCI Rules?

Sure, but sometimes just running a 3-core to one of the 2-ways would be more convenient than two separate cables. It sounds as though the Irish wiring rules pretty much forbid the reidentification of any conductor with sleeving and require it to be the "correct" color throughout its entire length, which seems unnecessarily strict.Twin brown is all that is needed for strappers and the permanent and switched phase conductors can be taken with a PVC/PVC single brown, or a brown & earth.
Interesting, I hadn't realized that. I know Ireland (the Republic part, that is) has long followed certain European wiring traits more closely than the U.K. ever did, but is this specifically a more recent trend?Even twin and earth in any colours is not available in most of them. Singles in conduit is more common.
Yes. In the south the old phase colours were Brown (L1); Red (L2) and Yellow (L3), with Blue for Neutral.Speaking of which, am I imagining it or did I read once that between abandoning black as neutral and the full adoption of the current European coding, Ireland had its own unique system of brown/red/yellow phases with blue neutral?
I have to wonder what is the point in having insulated CPCs. After all, it's perfectly acceptable for ('single-insulated') singles to come into contact with earthed metal (e.g. conduit), so I wonder what is the concern about uninsulated CPCs?... Although there is a new standard which will come into force before too long which will mean that T&E as we know it will be replaced with a full-sized, insulated cpc.
I'm not sure that the cost would be 'minimal', but my main question remains "what is the point/purpose?".I suppose that if you're going to apply sleeving at every termination anyway it's probably just as easy to have the earth insulated throughout the cable to begin with, and adds minimal cost to a reel of cable.
As I've said, I can understand that ... I would not be all that comfortable pushing an accessory into a back box knowing that there were 2 or 3 inches of bare CPC which could theoretically end up touching anything (including live terminals) after that pushing had been completed!But as we've discussed before, it's really not clear why it was decided to specify sleeving at terminations in the first place, other than somebody just thinking "it might be a good idea."
Romex also has a bare cpc, I believe?I suppose that if you're going to apply sleeving at every termination anyway it's probably just as easy to have the earth insulated throughout the cable to begin with, and adds minimal cost to a reel of cable.

It's the norm here to leave earths bare (as it used to be in Britain). There's no problem identifying them, since all the other conductors are insulated.Maybe it's not to do with insulation but identification?
The absence of insulation surely serves as very clear identification. Indeed, anyone who knows anything at all about electricity would surely realise that a bare conductor could not possibly be anything other than a CPC (or other protective conductor).Maybe it's not to do with insulation but identification?
Unless it's a busbar...anyone who knows anything at all about electricity would surely realise that a bare conductor could not possibly be anything other than a CPC (or other protective conductor).
