I cut out a wall chase yesterday for the ceiling light.

Is in necessary to place the new 1.5mm cable in conduit. As I understand it, the conduit is just there to protect the cable from things like plasterers trowel, sharp fragments from the wall chase etc. I will be plastering it myself and have got the chase pretty smooth.

still any need for conduit?

You are thinking of capping



This is conduit.


This is trunking


Personally I would use capping, but you don't have to.

Best to use it incase the spread nicks any cabling with his trowel. A lot easier to plaster as well

I mean conduit someone--else, the white oval shaped one.

Will fill the chase myself Steve so might just not bother

The advantage of capping is that it goes in after the cable has been installed. Where as conduit you push the cable through it before it is connected. Conduit is also used so that at a later date you can pull the cable out with no damage, you can't do that with capping. Just saying.

My plasterer is careful anyway and renders the chases first, so for power cable I use nothing or capping, usually nothing. I aways put in more sockets than necessary.

For light switches where possible I use oval conduit, fixed into the chase with blobs of adhesive, (oval conduit clips are thumping expensive) - you might want to change the switch to more gangs or 2 Way switching, in future.

For TV Aerial I use round conduit, as technolgy moves on you might want to change the cable spec., or run Cat5/6 network cable, or whatever they come up with next. But it seems HomePlug enabled double sockets or wireless smart tv's will be the way forward so probably wasting my time & expense.

I rewired my property about 8 years ago and went mental with cables, 3 coaxial cable (sky HD TV + freeview), Cat 6E (2 sockets) and a phone line. To this day I haven't used one in any room
I do wonder if all the wifi enable zones has a health effect!

Thanks Mate

Although as there is a sharp angle at the wall-ceiling corner, could you pull the cable out?
And realistically why would you want to?

Conduit does have the advantage that it may be possible to pull new cable through without damaging the wall, if some idiot plumber drills a hole for a pipe clip through it. Don't ask me how I know this, I just know, okay?

In my defense, everyone knows the cable from a light switch goes up from the switch to the light fitting, right? Well, it doesn't when it's a 2G2W switch on a landing that also operates the light at the bottom of the stairs. I'm sure the idiot plumber in question has probably filed that safely away under "mistakes I will hopefully only ever make once".

And on another unrelated note. i just realised that was my 3000 post further up. Should I have another Whisky?

Having a Laphroaig and watching a TV documentary about the universe and cosmology. Mind blowing. My cable chase query seems a bit insignificant now
