can you use 3 phase SWA cable for 230vAC single phase?

[JohnW2]

I regularly use the swa as a cpc, does that make me bad lol

Probably in some people's eyes (like Bazza's) - but, as I said, many other people would regard you as 'good'

 

[JohnW2]

If i were wiring it up with SWA then and that was me I would use the Brown for live, Grey for Neutral (sleeve blue) and black for earth (and sleeve) then another earth for the gland for the steel armour of the cable - 2 earths then , black core and the steel brading of the swa. - but if oversleeving illegal over here then thats another issue.

That's what I would do - but, as you say, you seem to live in a country in which that is not actually allowed

I don't see why some methods are said to be undesirable because someone in the past has done a crap job.

So why the swipe at me?

I said the way I prefer, each to their own, no need for a swipe unless you are looking for retaliation. Completely uncalled for comment.

@Risteard sorry to tax your brain but if someone (residential person/unqualified electrician) in Ireland buys a electric cooker from currys , gets it home and disconnects their old cooker and installs the new cooker are they breaking any laws how does the law stand in Ireland for that? - I see if they get an electrician to put the cooker in and they do not sign off the work and give a certificate to the owner thats illegal now, but even that is the owner being illegal still or is it just the unqualified electrician thats being illegal because they are unqualified and didnt supply a certificate?

Connecting a cooker to an existing cooker outlet would be minor works. Installing a cooker circuit would be Restricted Electrical Works.

I reckon that , potentially, there are pros and cons with both the differing regs and indeed there could be said to be pros and cons with having both armour and a core as "earth" any doing so, personally I am a both by nature whilst I do agree that armour alone is (usually) acceptable at least over here.
Interesting how being use to differing regs gives us some differing outlooks too - sailor vee as del boy might say I suppose.

ah right I see thanks

I like the "2 Earths are better than 1" of it - i mean if armour goes rusty/corroded you still have your earth on the core wire, and if the core wire gets broken then you still have the earth on the steel armour.

Maybe the UK/Ireland 3pin BS 13a plugs should have been made into 4pin plugs a long time with 2 earths in them so if one failed then the appliance was still attached to the other earth?

You've actually got 4 differing lots of regs for domestic work. Scotland, Ireland and Wales are all different from each other as well as different to England.

messy - it should all be unified regs (well definitely in the case of England, Scotland, Wales, NI)

 

[JohnW2]

I think you're being unnecessarily over-sensitive - there was no 'swipe' ....

I had pointed out that electricians seem to be split into two camps, one 'favouring' reliance on SWA armour and those 'opposing' it. Since you had previously written ...

I never rely on the armour as a cpc. I have seen too many terminations where the armour is corroded or the gland has come loose.

... I took it that you were in the latter camp, and therefore, since you had make that statement in this thread, mentioned you as an example of a member of that camp. No criticism or judgement, lest alone 'swiping' but merely a statement of apparent facts.

 

[JohnW2]

It's not really as bad as it sounds. The underlying regulations ('The Wiring Regulations', aka BS 7671) are the same throughout the UK - it's just a few legislated things that differ between the countries.

 

[JohnW2]

I agree.

That would probably only have made much sense if the two 'earths' got to the sockets by different routes, and that would have required major changes to wiring practices (and a fair bit more copper).

No we do not.

Regarding the comment flat 3 core and earth cable is not used in Ireland.
What type of cable do you use for timed bathroom extractor fans?
