In your country, do you use pipe to run wire through very much?

[nicebutdim]

1 of the reasons is DEPTH. capping or oval tube can be buried plaster depth. 20mm round conduit requires chasing into brick.

Yes but why ?

Why do we make it harder for ourselves and ensure every single track etc is conduited. I've been asked and have asked it of other Northern Irish sparks for years and no one knows. Just that if you attempted to not use it here you would be laughed off site

How many times have you been able to pull a new cable through old conduit that's been in a wall for decades?

Surely that small amount of additional work at the outset makes life much easier for all concerned?

Yes, good to have forward plans that make future additions or maintenance easier.

Also the steel conduit provides additional safety in case someone drills the wall - not against a serious effort to penetrate, but at least it safely shorts out without needed RCD protection.

In domestic situations I've only seen PVC conduit used. Others will be better placed to explain why it is used in every installation, but I always thought the basics were to protect the cable from trowels and also make future repairs or additions more straightforward.

My experience is minimal, but I've replaced cables by pulling through 30 or 40 year old oval conduit and was extremely grateful for it being there.

nor are they here. new builds are generally costructed from weetabix and cardboard, with an outside skin of real brick to support the roof, make them look pretty, and to cover up the bodged construction.

You get the point I'm making - for the most part those conduits have to be chased, but think how much easier your life would be if this was the case in every home you were called to.

I don't think people are being arrogant on here. Perhaps if you made it clearer what you were saying/asking/wanting to know, rather than just putting 'can you bend pipe?' and leaving it at that.

are you able to read? what does my question say? please cut and paste it. Did I ask "can you bend pipe?" let me know what you find.

WOW!! I'd never heard of oval conduit before you said it. I just googled that. Interesting!
this is why I asked so as to generate people's common products that might not be used here much at all.

in oval conduit, is it just one romex wire? or can you pull multiple wires for that?

I saw a box made for it, with oval knock outs. very interesting

Round conduit is more commonly used here these days and bushed into boxes, but some local electricians would be better able to comment.

The installation I mentioned, which used oval conduit, is 30-40 years old and the conduit was squeezed at its end to fit through round holes. Not perfect, but good enough for me to pull a new cable through and certainly simpler than opening up a wall. Like all conduit/pipe, it is available in different sizes.

plastic oval conduit is pretty much only used on rewires to protect romex style pvc flat cable when it is recessed into a solid wall.
it is never used for surface wiring and generally can’t be bent or formed.

The title of this thread maybe clear but your opening post clearly states "can you bend pipe". There seems to be a lot of attitude on this forum of late.

This forum is tame compared to a sporting forum that I belong to , there are regular users on that forum who hurl abuse over even the slightest disagreement...

The (approximate) UK equivalent to USA romex is our "twin and earth" (T&E) cable.

In the typical UK case the CPC (earth/ground wire) is uninsulated within the overall cable's sheath, however, it the CPC should be sleeved in green/yellow at the ends where it connects to the sockets, etc. Also here the CPC is a size or two below the line/neutral conductors (e.g. 2.5mm^2 L&N conductors with 1.5mm^2 CPC).

The reduced CPC size, along with its unsheathed construction, makes the cable overall smaller and easier to install, also cheaper. However, we have quite a strong requirement on the design side here in the UK to make sure the over-current protection disconnects fast enough not only to prevent the CPC overheating, but also to avoid prolonged exposure to high touch voltages during fault clearance.

In mainland UK most domestic work is in T&E and conduit is not so common. Many decades ago singles in metal conduit was used routinely for domestic and you will sometimes find T&E pulled through old conduit when rewired (instead of the singles that would be the norm in industrial style conduit installations).

Just for clarity. Nearly every single domestic property in Northern Ireland is wired in twin and earth and piped in 20mm PVC conduit down the chases using adaptors and metal flush boxes. Obviously a stud wall, which is becoming more and more common, it is just pushed down and a grommet is used to enter the box.

I've also always been told its to protect the cable from Trowell etc. Just no idea why we do that here and the mainland UK can use capping ?

the main advantage, apart from mechanical protection, is ease of rewiring , as and when needed, either due to age, or due to a drilled cable. saves chasing the walls out again. the reason the UK uses capping is to cut costs. quote for conduit at an extra £££s on the job over here, and you'll lose the job through price. new builds are thrown up as cheap as possible (e.g. dry lined , studded walls etc.).

When I was House bashing, we used Split METAL oval conduit rubber grommets at both ends, and CRAMPETS to hold conduit in the chases. Happy days.

Its a race to the bottom here aswell price wise though and no one would cap a cable into the wall. Don't get me wrong I feel it's the proper way of doing it just find it strange that we have adopted a different method.

Worked in Australia and they grinded a slot down the wall and poked the cable in with their screwdriver ffs

Well that is where the criminal element ended up wasn't it?

can you bend pipe?

Absolutely, I have a hosepipe that i bend every time i wash the car.

This is a photo off the web of home being built in the Chicago area, Chicago, & a number of it's suburbs only allow EMT when wiring homes, no flexible wiring methods like NM cable, AKA "Romex®", MC, Metal Clad cable, or AC, Armored Cable. The claim is that it is a result of the Chicago fire, but is more likely make work rules forced by unions.

Note: the salmon colored plastic pipe is for fire sprinklers, required in new homes now.
