Didn`t want to continue hijacking topic, so thought I`d move this here.
with regard to the discussion (argument if your name is Steptoe) r.e. correct usage of colours in 3+E.
I was reading the "Practical Electrician" mag, that the wholesalers tend to give away. In the May issue, there is a couple of pages on smoke alarms and BS5839.
At one point, the "professional" who is answering the questions is asked which colours should be used for wiring interconnected smokies.
The answer:
Brown: Perm. Live
Black (sleeved blue): Neutral.
Grey: Interconnect.
So is Mr. Steptoe suggesting that this BS5839 "expert" is wrong; and therefore the whole readership of a nationwide electrical magazine, OR
Are we saying that "If they`re smoke alarms, we do it this way; otherwise we do the exact opposite" OR
Are we saying that different standards apply to the cable when used for fire detection, OR
Are we saying that there doesn`t appear to be a standardised format for this; and, until there is, we`d all better be very careful that we`ve correctly identified the conductors.
