Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
can you use 3 phase SWA cable for 230vAC single phase?
I see nothing in the any pre-2022 editions of the regs which says that that was "the only time it has been allowed"

I really don't care what you "see".
My training was with the Electricity Board, and it was always emphasised, Your training was where?
Well, you should, since you appear to be 'seeing' something which isn't there.
My training in reading (which is all that is required here) was at school.
I don't understand why you persist in victimising/bullying me - does it give you some sort of thrill, or what?

I am neither victimising or bullying you. I am telling you that your information is incorrect.
Thank you, I only hold 16th (2nd ammendment), in which the second para of 514-04-02 only mentions single-core cables giving rise to the ambiguous interpretation of the first para.
514-04-03 has slightly different wording, I wondered if there was more to it.
Over sleeving the green or green/yellow in multicores has always been a very common thing, especially in the controls environment, Like John I was under the impression in earlier versions it was perfectly acceptable.
Of course in 8th, 9th & 10th editions Green was phase 3 and 7th green was neutral. there may still be some legitimate installations from that era, plus prior to my birth; earth wires were bare or black, never green.
More recently the national grid still used green as a phase colour, some pylons even still sport some older markers.
I used to purchase 7 & 8 core cable (for entertainment lighting especially mobile disco) which had both green and green/yellow.
To really put the cat among the pidgeons a short while ago I identified a T&E being used as a 3 core. However I was pointed to 514-04-06 'Bare conductors'... I let the boss deal with that!
EDIT. Someone on here has phase markers at their cutout: Red, blue and green, it may be John.

... and, as I've said, it remained like that up to, and including, the initial version of 18th (2018)
... as I've said many times before, in the many discussions we've had about this over the years, I personally see no particularly ambiguity. It would have made no sense for them to single out single-core cables for the statement prohibiting over--sleeving if their intention had been that it also applied to multi-core cables, would it? If they had intended the statement to relate to all cables (single- and multi-core) they surely would just have prohibited oversleeving of G/Y (without mentioing 'single core'), wouldn't they?
For the above reason, I would say that such is not just 'my impression', but seemingly the only sensible interpretation of what is actually written in the regs - which is why I don't understand how/why Bazza continues stubbornly to insist that this isn't true.
Yes, it is John
. Note the exposed inner insulation of the wrong colour in the neutral block (the evidence subsequently covered up with grey silicone by a meter changer
). Nte also that when the tails get to the meter,they are labelled "A", "B" and "C" !! .... .... 
No, it is not.
I am afraid that it is you who is incorrect in the matter of oversleeving the green & yellow conductor in multi-core cable up until the latest regulations.
Thanks for agreeing/confirming.
Given that it is seemingly being suggested that the number of years (if any) 'in the trade' are an indicator of the correctness of one's knowledge about the regs, would you be prepared to share with us the number of years you were 'in the trade'?
Kind Regards, John

Can we please have all traces of this abomination removed:
No part of Derry lies within the Republic of Ireland, it is entirely part of the sovereign territory of the United Kingdom of Great Britain and Northern Ireland.
This is the flag for the nation where Derry is:
Do you understand that?

And presumably a person who can understand that "an earthing conductor has to be green&yellow" does not also mean "a green&yellow conductor has to be earthing". Why do some people find that so hard?
You have to be over 16 to buy tobacco products. Doesn't mean that if you are over 16 you have to buy them. Would they argue with that?

How many people have been jailed in Ireland for doing their own electrical work?
Indeed - but that is, by implication, what was being suggested.
That's what I suspected, so ....
Good question. In the eyes of some, it may or may not have been long enough for you to have correct knowledge of the regs!
Presumably because they have some problem, either with reading or with understanding.
Maybe per above, but perhaps because they are obsessed with 'the need to be right', even when they are wrong?
