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

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).

Well on a ring final the 2 earths do come from different routes

Very true. Indeed, as I always say, I think that 'CPC redundancy' is one of the few 'positive' things to be said about ring finals.

However, with such a circuit, I don't think that the OP's hypothetical "4th pin" (second 'earth pin") would, per se, achieve much, since there would be a requirement for "both earths" to be connected together at each socket, in order to maintain the CPC ring.

I was thinking more of a radial, when to make useful use of such a 4th pin, in addition to the CPC joining allsockets (and eventually to MET), each and every socket would have to have its own additional CPC run back, directly or indirectly, to the MET.

Not being over sensitive at all. You took a dig!

I did not take it that way Bazza

And increase the price of every job because the spark has to now allow time to identify each and every conductor.

What a good idea - not!

Are you implying that sparks do not allow time to identify each and every conductor?

 

[JohnW2]

Not being over sensitive at all. You took a dig!

That is a contradiction in terms - since there was no 'dig', and no intended 'dig', the fact that you 'took it to be a dig' is an indication of your over-sensitivity.

I rarely do 'digging', leaving that to others who seem to like doing it - and am often the one on the receiving end of it

I don't particularly care how you took it, it wasn't aimed at you.

Not at all. Identifying the conductors by colour, letter, number or connection takeds a lot less time than identifying a conductor with absolutely no marking and surrounded by other conductors with no marking.

You did not need to include my name in the statement at all, hence it was a dig.

I'm just looking out for you. I like you too much Andy From Sligo to see you doing hard labour.

Thats nice thank you - i dindnt know if you were doing it in my interest or yours

It does, but one is then reliant on the colour, letter or number, as installed by someone else, being correct. Are you totally confident that such will always be the case?

 

[JohnW2]

I don't understand your concern, or why you are going on about this. Don't you have something better to do in the nice weather we're enjoying this weekend?

I merely included your name as an example, since you were the one person who had spoken out in this thread fairly strongly against reliance on SWA armour - are you in some way ashamed of that view, or what?

I suggest you 'cool'

 

[andyr123]

Look at it this way, what test equipment do you have? Do you know how to use it? Do you know how to interpret the results? Can you be certain it's safe and compliant?

@Risteard has all the equipment, knows how to use it and will certify the work in accordance with your rules.

Sit back, have a beer and let a pro do it for you knowing that it's done properly and safely. He may even teach you a little while he's there if you give him a cuppa and a biscuit.

Simples!

i got one of these socket wiriring testers to see if a socket is wired up correctly - so easy a monkey can use it :

then theres always my digital multimeter to test continuity / resistance, and the RCD in the consumer unit with the 'Test' button to test out the trip works on the RCCD

I used to work on electrical trade counter in a builders providers in the 80's in the UK for 3 years so used to pick up bits and pieces of 'info and how to do' from the electricians who picked up their stuff (granted things have moved on since then in terms of electrics and regs) at nearly 60 I am too old to go on any courses and become a fully qualified electrician , so its just as a hobby now.

unfortunately yer good man Risteard is located miles away from me up in donegal , so sorry to @Risteard I would have to be getting an electrician nearer to do the job, soz!

 

[andyr123]

no, trust no-one , thats why i reckon electricians should not be just looking at colour and assuming everythings correct - how many times have you waited to turn out onto a road and someone puts their left indicator on in their car and they still carry on driving straight forward ... you just wait there for safety , you cant assume .

I happen to live in a country where over-sleeving isn‘t allowed either (at least for earth, neutral is a bit of a grey area) and the answer to the fan question is „use five core“ (full-sized, insulated earth, so it counts as a full core).

 

[andyr123]

oh , i just found this on the screwfix forum , shall have to havea read - mind you , still no good if our countrys reg prohibits over- sleeving though.

Exactly. That's why I'm surprised that there is so much fuss about this 'colour identification' business, and some 'rules' in ROI which seem to be essentially 'unnecessary'.

- how many times have you waited to turn out onto a road and someone puts their left indicator on in their car and they still carry on driving straight forward ... you just wait there for safety , you cant assume .

Again, exactly.
