Looking for the perfect sleeving size for the CPC in 10mm T&E

[sparky1983]

I have 3mm and 4mm G/Y sleeving and can't see me using the 4mm sleeving. Gonna return it I think. Made the mistake in mixing up cable size (mm²) and diameter(mm) when purchasing.

Anyway, this 3mm sleeving provides a lose fit on 2.5mm² copper core. Anyone know if provides a 'just right' fit on the CPC(4mm²) in 10mm² T&E or a 'tight' fit?

Thanks in advance

If you've got some why dont you try it???

3mm is normally nice and snug.

Well, there might be some 10mm in my firm's office. Just a bit impatient I guess. Going back to my local wholesaler Wednesday. Wanna get my money back on the 4mm sleeving see.

Heatshrink is always the perfect size

Cheers barx, thought it might be.

3mm is quite tight on 6mm² copper core, and that's only in 16mm² T&E. Not going to be using that anytime too soon. 4mm's good for that size, but going to return the 4mm sleeving now.

Yeah, lol. Heatshrink would be

Where's the heatgun now......

Also, while on the subject barx what size sleeving do use to indicate 1.5mm² switch lines in lighting? I bought some 3mm brown and it just seems too tight

3mm will be a little tight, however 4mm will fit fine BUT, you must make sure that when you strip the 10mm that you give the strands a couple of turns to tighten them a little and keep it DEAD STRAIGHT.

Trim the end and slide on your sleeving.

I will also point out that some sleeving is quite 'stiff' and doesnt bend or stretch very well.

One i find that does have a bit of give is the Niglon sleeving available here:

4mm Earth Cable Sleeving ( 100M Coil )

Sorry but at £5 for 100m what are you on about.
5mm Earth Cable Sleeving ( 100M Coil )

I know it's no BIG deal, sleeving etc. But I know what I need now. Btw, I think some sleeving having more give than others might be something to do with the wall thickness of the sleeving. After all it's all PVC.

Anyway, thanks for the advice.
