Colour code for 3-wire room stat?
I'm just replacing an old room stat with a new one. The old one is the
2-wire (plus CPC) version, and the new one is a Honeywell 3-wire (plus CPC). I have no problem with the actual wiring (cable is already run). However, is there any convention for which of the three colours is used for live, switched live, and neutral? My instinct would be brown for live, grey for switched live, and black for neutral.... -- The information contained in this post is copyright the poster, and specifically may not be published in, or used by http://www.diybanter.com |

Brown for line, black with brown sleeve for switched line and grey with blue sleeve for neutral. Use of a black core for neutral is strongly deprecated since it is now a line (phase) colour. -- Andy |

I did wonder about the black, but was pretty sure about the brown...and yes, I do have brown and blue sleeving...

Perversely, I've heard of a lot of people (IET Forums) trying to avoid black for neutral to positively break the old association (eg 3 core SWA taking L/N/E to a shed). I think that's taking things a bit far, but it's what I've heard. Everyone seems agreed that the usual single phase line colour (ie brown) is a good candidate to use for the permanent live. At the end of the day, as long as it's sleeved correctly to remove all ambiguity that's what matters most, but grandma, eggs etc... ;- Cheers Tim |

Nice try, but it wasn't dreamed up by the EU. Neither is it crackers. It was "dreamed up" by the IET. They gave members and interested people some time to cogitate on the matter. To make cogitation easier they provided a table of wiring colours in (IIRC) at least western Europe. I couldn't think of a better solution to the one they implemented, but if you can do so then why not suggest it to show that if only they had asked you they would have been amazed by you spotting something thousands of others didn't. By the way the main issue was not with black, that was a fairly easy one, but whether to retain separate colours for each phase and, if so, after brown and black what third colour to use. Grey was the best option for this third colour in my view. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

Grey was the best option for this third colour in my view. In my view, they should have left it alone. Red, yellow and blue were not only fine, but visually very clear - far better IMHO than brown, grey and black. Whilst I can see the merits of harmonised colours on appliance flex, as those are made and marketed across the world, I see few merits in EU harmonisation down to this level. Just my 2p's worth.

Dingley wrote this:- The whole problem stems from the problematic re-use of blue & black. Blue was only used in three phase wiring. Anyway the harmonised blue is a light blue, not the deep blue of the L3 conductor insulation. Black is a more difficult case. However, my recollection of the discussion is that it is used to indicate an energised conductor in several wiring schemes and thus it made sense to adopt it. So we shouldn't have done this - there's hardly a shortage of other colours. "We" did this in the interests of standardisation. My recollection of the discussion is that the "plenty of other colours" become fewer when one looks into it. It is most unlikely that people would adopt a brand new wiring colour scheme just because the IET devised it. -- David Hansen, Edinburgh I will *always* explain revoked encryption keys, unless RIP prevents me http://www.opsi.gov.uk/acts/acts2000/00023--e.htm#54 |

It's the sort of thing that could only be dreamed up by the EU. Does seem strange to me too - since most used blue for neutral on the old colours when using three phase wiring for this purpose. But I can understand the reasoning behind it. It might make sense to have triple and earth available for this purpose where the colours weren't used for anything else. Or even three browns would make sense. -- *If Barbie is so popular, why do you have to buy her friends? * Dave Plowman London SW To e-mail, change noise into sound. |

Some are neutral but I don;t recall a single person praising it as a radical improvement that is solving a problem that everyone's been grumbling about for years. Coming up with a less crap domestic installation cable than T+E would rate higher on my personal list. To me it appears an wholly unnecessary change from a perfectly well understood and clear system. Then I didn't have some invisible body pressurising me to "harmonise" for the sake of it. Having used some new triple + E, it's a bloody pain in dimly lit areas to discern the colours - no where near as clear as R/Y/B. How can this possibly be classed as "progress"? Cheers Tim |

Exactly Dave - they should have left the whole installation side alone and lead red/black as the single phase scheme. It would probably have been betetr for everyone if the appliance flexes had been left alone, but I've already said that I can see the point of a world standard for those - pity it wasn't our standard.

And having standardised on one set of colours for flex- why have different ones for rigid wiring? Makes no sense at all. If we were starting with a clean slate, I'd agree. And *most* everyday flex is single phase. If we all had 3 phase appliances, I'd whine like buggery about having black and grey in those for the same reasons. But fixed wiring is in a fairly clear and contained domain. Red and black is probably more obvious to the uninitiated than brown and blue, so it's clear. And we're changing from a system that caused no-one any problems. Out of the whole think, I think that re-using black as a phase colour was probably the most insane decision. A *lot* of sites are going to be sporting mixed installations for the next good couple of decades. All I'm saying is why change from something that was clear and established to something that is IMHO less clear just so some comittee can sink back and indulge itself in a well earned post mastabatory cigarette? Most of the output from the IET is sane and good and well considered. I really suspect they were "encouraged" to persue this colour standardisation for installation wiring by someone with a bee.

Snag is brown now denotes one of the phase colours - and triple and earth Hasn't it always? is three phase wiring. Yes - but with RYB, blue wasn't an old colour for neutral - unlike black is now. Do try and keep up. ;-) I do try, my failing was to assume your argument was logical - I thought we were talking about brown, not blue ;-) -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

A *lot* of sites are going to be sporting mixed installations for the next good couple of decades. Anybody who is able to cope properly with three phase wiring is unlikely to be bothered. The new colours seemed strange to me at first, but they soon became natural. I can cope with both sets of colours without thinking now and I don't do wiring every day. If the IET have made a mistake then there should already be an observable effect. AFAIK there has not been one. There has been a rise in fatalities from fixed wiring recently, although I expect most of these have been caused by part P - three phase does not feature often enough in domestic work to figure. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Then she remembered she was using the wrong aide-memoire - brown is line, because that's the crispy colour you turn if you get it wrong. Personally, I prefer brown as the colour your trousers should be in case you get it wrong... -- The information contained in this post is copyright the poster, and specifically may not be published in, or used by http://www.diybanter.com |
