conduit, what is the reason for it to be used, where do i have to use it, and where do i not?..

what size should i use, and do i only need it on the long parts, on the verticals, and horizontal and is it fitted to a metal backbox?.. or is i just short of a BBox, to allow the wiring to happen.. before being plasterd over
 
Do you mean conduit (that is round tube)
or
do you mean cable capping, thats like a U profile with flat bits either side.
 
Are you referring to plastic oval conduit?
Use whatever size is adequate for the amount of cables going down the run.
You can use it to stop the wire getting caught by the plasterers trowel, it is also useful if you need to pull another wire in.
You can cut it just short of the metal back box.
 
you'll have to be more specific.

conduit is used for a variety of reasons and is available in a variety of sizes and materials depending on the required use..
 
not sure..
i am guessin all kinds of condut.. i only know of the 20mm and 25mm round tube type, and well as the small oval type.. but i am meaning any type that is buried..and plasted over.

ok..

so is any kind of conduit, i.e. buried type- used for the concealment of cable, to save it from being damaged when the plastering is being done!
or is it also used so in future the cable can be pulled out, and new flex replaced without ripping the conduit out the wall?..

just wondering..

maybe if i knew the latest reg's and legislation for the use of, i will be able to answer me own question

any ideas..

i work in pre fabricated modular bulids... in this case...all our fitted conduit, from start to finish every part is glued , and strung with marker tags,..ready for the sparkies to pull the correct spec cable through..
as once it is in situ on site.. any problem with the conduit is not fixable. so we have to get it right, first time.

but this is not the case for our homes.. in DIY.
 
You can get different types of conduit and different shapes, the different shapes mainly in plastic.
You can get 20mm round PVC conduit but will take a bit of chasing in. Oval is easier as the chase doesn't need to be as deep.
Neither of the above offer additional mechanical protection to the cable against penetration by screws, nails etc. This means for this the cables need to be in safe zones and protected by RCD.
Metal conduit can be used to provide mechanical protection and if it is earthed there is no need for the circuit to be RCD protected (unless for another reason i.e. bathrooms, socket circuits, TT systems etc) however metal conduit requires expensive tools to install it with.
 
cheers all..

yeah i hear you spark

nice one. yes it is in a safe zone.. vertical.. i will go for the oval option.. as it means i am within the spec for the chasing out.. in the brickwork.

You ought not to be installing cables if you don't know the applicable regulations.

Surely then you'll be DIYing at home with the type of conduit used at work? :lol:

DUDE..

do you simply respond to everyones posts on here, to stab at the questions asked?.. when will you ever give a gd dam answer..without a quip.. or snide remark, my work is to strict MOD standards, i.e. (Blast/Bomb/Fire Proof) for your own information is nothing like what is required in a residentual home.. so you tell me.. how deep is it meant to be buried then, go on. please..i am waiting. is 600mm min depth correct?

stop making your life feel fulfilled in having something to do, when really i cant see why you are here.. my questions are simply and basicly asked, for the simple reason - as i am on a budget, but i wish too, and plan to do things correctly, but in asking on here, i hoped to get the information that i need, to help plan, purchase, and arrange work to be done. if i can dig a trench to save time, to save the overal cost, then i will, but only if it is correct.

this is the last posting i will ever bother to do on here, re any questions as for mr "Ban all Sheds"...
still waiting for your answer

not that i will read it. as you will only point out my obvious spelling errors on my posts..

oh its good to give someone something interesting to do, dont you think! :D

Cant think of any pre fabs that the MOD would call bomb proof, but moving on..........

Conduit in metal when earthed allows circuits fully contained in the conduit to be outside the requirements of 17th ed RCD or RCBO protection. That is one reason metal conduit would be used in a domestic situation. And there's the obvious sensible use in cement / concrete / scree required runs

Nearly all good domestic work will use tube in oval or round conduit for the facilitate the entry and exit of cables, light switch wiring especially.

Reason is as you remarked- in years to come upper floor boards or loft to switch location will be easy for rewire / service work.

Sometimes I think BAS comments are harmless, and in honesty you need to accept sometimes people may think about your (unknown) abilities.
Frequently the odd daft sod comes on this forum and posts in a manner that suggests they have little understanding, so little that there's a danger of self harm.
Better safe than sorry and if it means someone like yourself has to offer up some evidence of understanding what you may be getting in to- it's not a bad thing.

If I was a newbie poster on a bomb making site and you were a expert, would you freely offer detail to someone that seems to be very unsure ?
 
did an incinerator in a container once.. they clad the thing with thick steel plates on the outside and some fiber looking stuff inside ( kevlar maybe? )

It wasn't a quip or a snide remark - it was a perfectly valid observation.


so you tell me.. how deep is it meant to be buried then, go on. please..i am waiting. is 600mm min depth correct?

I don't see it as my role, or anybody else's, to spoonfeed people with answers to individual questions so that they don't have to put any effort into actually learning something themselves.
