Bathroom extract fan, no earth

I also think that every cable should have a connected CPC, regardless if it is functional for a piece of equipment or not.

Gents, checked with NIC, the g/y is not g/y if identified otherwise, however they reccomend full sleeve as I said rather than a ring of brown tape.
No regulation to contrevene other than identification of conductors if you don't do it. We are talking about a condutor in a flex, not a bare in T/E or a single. Its no different to marking a blue brown, that's why we do it.

What I said was that it was prohibited in the 16th Edition but is no longer prohibited (although I believe it should be). I also believe that it should be prohibited to simply oversleeve another conductor green/yellow (e.g. in 3-core SWA being used for single phase application).

I don't think the NIC should be encouraging it.

Incidentally, we work to the IEE Wiring Regulations and not NIC ones.

Whys that mate?

What about the 2 core flex on the end of my drill/tv/radio etc?

my understanding was that the cpc could not be sleeved as in some cases (ie t+e )the cross sectional area of the earth was less than that of the line and neutral but dont know if that applies to a multi core cable if the accessory requires a line,neutral and sw and no earh then what is to be done

install a 3core + earth

I think Jason means permanant wiring and points should have a cpc for connection to whatever equipment is installed in the future...not a flex to a class II appliance in which a cpc would be pointless.

Regarding the re-identification of other coloured conductors being no different to identifying a G/Y as a live I think it is...the hazards of misconnecting cores of colours expected to be energised are infinately less than connecting an energised g/y core to the earth terminal of an item of equipment exposed to touch.

Fair enough, I just had visions of people being pulled up for running a 2 core flex between downlighters and such like.
