Discuss In your country, do you use pipe to run wire through very much? in the UK Electrical Forum area at ElectriciansForums.net
I had a play with that once, didn't like it at all, the pipe entry holes were a bit big and the locking screws are tiny!there is a system available which uses standard steel conduit and the boxes have plain entries with a set screw to secure the conduit, i think it is called conlok.
Regarding you point about rewiring it's always an advantage but in reality there is no way the bigger size T&E we now use can be pulled through. Oval conduit is already user unfriendly for rewires. I also don't think it is necessary to allow for future rewires (unless damaged).
If you pull 2 ends straight off the cable roller (no kinks), you will push them through a horizontal piece of 20mm pipe OK.I doubt the original intention was to provide for future rewiring, but it would be one added benefit in some cases. Obviously not every section of old conduit will serve that purpose, but think of 20mm round conduit dropping to a 1G switch plate - that's going to be easy to pull a cable through if the need arises.
I take it there's no chance of getting two legs of that new Irish T&E through 20mm?
Your a lot younger than I thought, steel conduit drops where all about rewiring, using fabric covered cable needed this facility as the cable insulation deteriorated.I doubt the original intention was to provide for future rewiring, but it would be one added benefit in some cases.

I've come across quite a lot of both rubber and PVC insulated fabric covered conduit cable here, and it is often in excellent condition! Of course old rubber cables should be replaced as a matter or course...using fabric covered cable needed this facility as the cable insulation deteriorated.
I’d disagree with you steel conduit is used to enable the use of single core cabling to provide a suitable means of protection and also enhance the space of wiring in single core cable you wudn be wiring a new build council office in twin and earth through galv it is single core so I don’t think age is a factor in your postYour a lot younger than I thought, steel conduit drops where all about rewiring, using fabric covered cable needed this facility as the cable insulation deteriorated.
All the drops I have done have gone into steel trunking and required a 90 degree bend sometimes included a set or double or even bubble at worst case lol I suppose different jobs have different specs but my experience with galv is that it’s galv all the wayIt is when you take into account when conduit drops where the normal thing to do, all switch's and sockets where cabled by a steel conduit vertical drop form the roof or floor void above or below, there where never any horizontal or zones, it was just straight drops to the sunken box, but as you say T&E did not exist it was always single core cable.
A man of your experience should know better ?never got the hang of that steel conduit stuff. put it on the bender. hit it with a sledgehammer to bend it... it squashed flat.
Who thought that times would change heyTo be said in a broad Yorkshire accent: Eye when I where a lad, who'd of thought I'd be on ere talking about conduit drops in galvanised steel.

You don’t tend to have steel conduit in domestic properties mate, oval pvc conduit or capping is more common, steel conduit is more commercial, industrial although I wudn be surprised if domestic rewires in 10 years time will have to be done in steel conduit with less money that is currently paid for a Rewire is disgraceful the lack of appreciation shown for sparks in most casesI can only comment on that which I've encountered in domestic properties in NI and have very limited experience of this subject.
In my lifetime it was originally oval conduit and latterly round. These have all been one form of plastic or other.
Haha great ??Whipersnappers.

What? Capping unheard of? PVC conduit run “IN” solid walls not “ON” is that what you do in Ireland?The thread seems to be covering quite a range of situations, but I'd originally commented on posts that related to the slightly different practices employed in NI. Here capping is unheard of in domestic properies and PVC conduit is used anywhere that cables run in solid walls.

steel conduit in domestic is not normal just capping is, goodnight ?Yes do it the easiest way you can, nailing a PVC capping over a T&E and calling it protected is the way the industry goes now days, it took a lot of skill and dedication to put in a steel conduit, even if it was just a straight drop or rise out of the floor, but as with everything, time is the biggest factor now days, speaking of which it's time I went to bed, goodnight all.
Depends what your talking about? There is a whole variety of specs some have surface conduit some have buried but yes all the containment is generally run in prior to installing cable that’s usually on the schedule of works and timescales but not in domestic works? Not talking about domestic rewires surely?Conduit chased into walls, which the rest of the UK seems to think is crazy.
I can not state with absolute certainty that every spark works to the same standards, but accepted practice is to chase for conduit and boxes before any cables are run.

Wow! Conduit all the way over there then! Steel or pvc?I've never known any electrician in NI to not use conduit when running buried cable down solid walls in a domestic property, whether it be a new installation or a rewire. It's standard practice over here.

Different coloured conduit... but all their currency is the same colour ???@pc1966 you just taught me something new. I didn’t know that they even made different colors of conduit.

Thrown off site? No you mean if the spark didn’t follow the spec for the job in question then he would be thrown off site. If it was a requirement to provide cabling in pvc conduit prior to commencement of works then of course that would be what the spark would do. So why would capping be laughed at? We are clearly on different wave lengths here. What about your occupied social rewires which I was doing in 1 day with a 3 man team? Do your sparks do that also?PVC.
To be clear; I'm commenting only on domestic properties as I have no experience of commercial installations.
This house is three years old and round PVC conduit will be bushed into every box. There would be no issue with undercutting on price as every electrician will be expected to do this. As one previous poster had commented; an electrician would be laughed or thrown off site if they placed capping over cables, in place of conduit.

Well you sound very experienced in my eyes and good that you voice your opinion, there are many regulations I can’t be arsed to go into all of them but to simplify it is to have rcd protection and all is well then. I’m sure most on here will agree that whilst carrying out a Rewire On domestic property will use capping Or oval conduit, unless it’s surface mounted and in that case it is trunking and with new regs fitted with fire clips.I do not know whether or not any regulation mandates the use of conduit in such circumstances here, but it is standard practice.
Others will be better placed to comment as my experience is extremely limited, but I've never seen capping used over here or cables buried directly in plaster. This practice extends back at least over many decades.
