Neutral is a live conductor...
Yes, that would definitely be sensible in three-phase and probably in single-phase too but if the joint is inaccessible you will still be unsure and have to test.Now obviously there may or even may not be coloured sleeving used, but for fault finding and future alterations, wouldn't it be so much easier if the wires were joined in the accepted
red-brown
yellow-black
blue-grey
?
And when you were presented with a red/yellow/blue cable, how could you be sure that blue was neutral unless sleeved black?Also, in single-phase, because of the silly colours used (BBG) and when one of them is neutral you will never be sure unless sleeved blue, will you?
That is a possibility but, as above, it was never seen that a yellow would have been used for neutral.And when you were presented with a red/yellow/blue cable, how could you be sure that blue was neutral unless sleeved black?
As you say - quirks - but I would always use the red for the permanent live strapper.One thing springs to mind is what colour to use as 'common'. It was usually red, if not, yellow. Rarely blue, for some reason. Not that I feel this is particularly important.

Maybe not, but does it call into question how sure you should be?That is a possibility but, as above, it was never seen that a yellow would have been used for neutral.
I don't think that alters anything I have written.
Red in com was certainly the way I was taught.
In one of the switches the red wire is permanently live (feed) and on the other switch the red wire is only live when the lamp is on
No.Even if you have never seen a 3C+E cable where the blue was not used for the neutral, would you trust your life to the assumption that it was?
