Brown/Brown twin and earth.

Looks very professional when used for switch drops but...

And I am braced for impact..

How do you know which is feed and return?

Installed a 12 gang grid switch and used Brown/Brown and when wiring up the switches was wondering if there is a trick to knowing which is which.

Was a bit of a faff but sorted it during dead testing today but thought, why isn't one core distinctively marked, or maybe a different colour, say blue?

I do largely agree with you, and you make some good, important points about the triviality of the colour code relative to other intractable differences between national standards, and the difference between political compliance and engineering compromise.

I remember in the consulation document the idea of a pink line being put forward, a similar flavour to red but not actually red, which was the most unsuitable colour to incorporate in a new standard owing to its diverse meanings. AFAIK it's the only colour that has served all five functions (GB: L1, US: L2, RU: L3, NL: N, DE: PE)

Anyway, switch cables. Brown & black anyone? Would we still have to sleeve the black core? Two kinds of brown? Colur tracers are more expensive but the rib shouldn't have much impact.

Light brown, dark brown? Seems obvious
Same materials, just a little more masterbatch in one core (colour)

Adheres to the standards and can be identified if required.

Or embossing one core with a symbol every inch and the other plane.

But no cpc, I’ll bet!
I’ll bet there’s none of that where Risteard trades!

Yes, CPC is present and correct.

L2 was white before it went yellow. I preferred white.

And it was green before it went white.

 

[Let me think]

You think we’ve got problems.

What about the Hollywood stars that have to defuse bombs. Used to be simply, cut either the red or the other coloured wire.

Now they need to know when bomb was manufactured by which standard did they use, before they can figure out the correct wire to cut just before the count down timer reaches zero...?

Can you imagine them contacting us about a cable colour (‘color’ for our Hollywood friends) question? and still not have a clear answer before bomb goes off.

Probable best they just guess, correctly, like they normally do. ?
