Ah right, you mean 2 core\3 core, not single phase\3 phase.

[Dave Plowman (News)]

Indeed. But since it uses the three phase colours and is rated at 440 volts I'd say it's a fair description.

Not knocking you in any way but it's a fair DIY description, as SWA isn't DIY to me then it does make me scratch my head a little when non-standard descriptions are used.

Each to their own I suppose, but I also find that some things are called entirely different things at each end of the country.

Didn't realise it was a non standard term. Three core to me would mean the three normal colours for single phase or other non related colours. But the fact that it uses the colours for the three phases - as does the present stuff with the new colours - suggests that this is its primary application.

Triple and earth ordinary cable is a bit more tricky since it uses the three phase colours but is probably most used for two way switch circuits in a domestic single phase application.

Absolutely. Ask for a pattress in a London wholesaler and you'll get a blank look. And ask people who have heard the term and you'll get a different description of what it is. I've settled on the old wood surface blocks that surface mounting switches etc were fixed to, so really doesn't exist today.

You can get 3 core SWA with 'single phase colours' I think, but no-one uses it so it costs a fortune. 3 core SWA in '3 phase colours' is a more common stock item so is cheaper and used instead.

I think (long time ago since I looked in some of the cable catalogues I have) you can, or could, get most cables in whatever colour you want. Everyone has settled on the sets of colours that are used currently for their correct and incorrect primary purposes as that's what is bought in bulk and therefore cheaper.

I used to have a problem with the term 'dual *something*', aspecially when I was ordering over the phone for stuff to be delivered to a job. In one area if I asked for a dual metal box I'd get a dual accessory box and in others a 2 gang box. Other places weren't really sure what dual meant.
