My Ongoing Domestic Questions...

Me again

Ok, oval conduit... 13mm 16mm 20mm or 25mm?

I'm going to get my hands on a wall chaser so depth shouldn't be a problem, so therefore I'm torn between 16mm and 20mm as I presume 25mm isn't really that necessary.

I know some may say don't bother with capping but I want to use it as its my own house.

 

[Spudnik]

Depends how many cables have to go in.

RFC get the 25mm as thats the width of my sds chisel.

 

[dim_bulb]

Get a load of each its cheap and you can use sizes for different circuits
Just keep it in a rhino tube on your van

 

[ezzzekiel]

25mm for extra room

Hi Stuuk1,
I use 13mm for 1mm T&E 16mm for single 2.5mm T&E drops and 20mm for double 2.5mm T&E cable drops 25mm for all others or if its a bit tight.

 

[Stuuk1]

Fantastic, thanks guys.

I take it you all leave the conduit a few cm above the box sunk in to the wall?

Also how do you attach this in the chase? With a crampet of some sort?

 

[dim_bulb]

6 mm or 10 mm cable clips or use a bit of earth wire and two screws
if youre chase is good it will be snug or just bash it with the hammer

 

[Marvo]

Don't you get male adapters that connect the conduit to the wall box?

I use floor/skirting board flat nails like these http://www.twwholesale.co.uk/product.php/site/froogle/sn/B/H31720
Bang then in next to the conduit, then tap them over to keep it nice and tight in the chase. Plasterer will love you for it !

I recently got some 20mm tower oval conduit, and after using oval 5 years ago my word it had gone down in quality, it's so thin! I use 40mm clout nails hammered in, nice big round heads hold if in well!

 

[telectrix]

drill and plug the proper clips for ech size of oval tube. then clip the tube in.

I only really buy 25mm oval and just bang it in with clout nails either side every 400mm or so. I also use capping a lot of the time just depends which is gonna be quicker and easier

 

[FAA Greenie]

I use either the clout nail method or, just lately i have worked out that my chaser is able to cut an exact size for a 25mm, if i put a deliberate ever so slight zig zag in every 250mm it fits in like a jigsaw, ideal!!!

I agree, but my zig-zag is usually un-intentional.....Must get eyes re-calibrated !!!

Slightly off question and perhaps I should start a different thread... But smoke detectors... Spurred off the lighting circuit at any point?
