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

[pete01]

I used to, but in my last 15 or so years ot so I found so many issues I always added an earth wire.

Inside a factory I cant see a problem, outdoors definitely use a separate earth

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.

The rules in Ireland are different to over here. Not even sure you are allowed to do the work over there.

Take notice of what @Risteard tells you. He is based over there and works both sides of the border and is fully licensed.

Those photo's were inside a factory. Lights on a paint line. The armour on 2 of the cables was live, that was how I found it

screwfix IE site has

4core 2.5mm 25mtr with these colours in it: Black, Blue, Brown and grey insulation colour €77.65
3core 2.5mm 25mtr with these colours in it: Black, Brown, Grey insulation colour €67.95
price difference of €9.70

so in that sense the dearer 4 core at least you would have the brown and the blue for the neutral and live and then could sleeve the black with G&Y (but we are not allowed to then apparently use sleeves here in ireland)

These 2 isolators also were not bonded across. The SWA was lay in water on the ground surface feeding 2 inductrial compactors.

true i will have to look up on that over here in Ireland - i am never sure if that it is OK to do your own wiring in your own house/property - but where the real issue is that if you have to get an electrician in the electrician must be qualified and have all the qualifications and 'write off' the work and give you a certificate. of course even to this day even in Ireland, people say buy a new light fitting from homebase or B&Q over here and wire it up in their house or wire in an extra socket with pattres to their home with a socket they have bought from B&Q say - or get a new electric cooker with 6mm cable from currys over here in Ireland and whip out their old cooker and dont necessarily employ an electrician to put the new cooker in and do it themselves .... so are they breaking the law too? - I dunno?

You will get all you need in terms of information and professional installation from @Risteard

Look up Walsh Electrical in Derry

I believe this is him

Minor works are not Restricted Electrical Works. However, even this is not always true as any works within a Special Installation or Location as defined in Part 7 of the Wiring Rules are Restricted Electrical Works (including, for example, replacing a faulty pull cord in the bathroom).

Makes no odds to me, IMO the armour only really suffers if they've been poorly installed or subjected to repeated submersion/corrosive gases. Rarely going to get that in domestic unless you fit it too close to the ground.

I have also seen many instances of indoor glands used outside.

That doesn't mean you have to do it though?

No, but I prefer to use the correct gland and a core for earth rather than rely on the armour, but I do ensure the armour is earthed too.
