cable routing behind plasterboard

Really?

3mm capping really would be something! Even though like most things its far flimsier (is that a word?) these days, its never been anywhere near that

(For comparison a metal k/o box is probably in the region of 0.8mm...well the appleby one I have to hand seems to be, theres probably 0.6 out there is you buy cheap)

Really?

My guess. Maybe I should I have put " 3mm or whatever it is..."

I just wanted to warn Godwinap that Doggit's advice was erroneous, without having to consult the British Library first.

How thick is it actually then?

 

[Adam_151]

Nearer to 0.3 than 3, I should imagine for the current stuff. Older stuff a bit thicker, possibly upto double?

Its a strange effect, people have a tendancy to over estimate material thicknesses inititality, its somewhat universal :S

Well built switchgear sometimes has a gland plate in the region of 3mm, it takes a bit of drilling to get through!

Apart from not being earthed, it would provide compliant mechanical protection were it 3mm - that's thicker than the walls of steel conduit....

Yes, I did.

 

[Taylortwocities]

Sorry, my reply missed something...

Capping of course doesnt protect the rear of the cable, at all. Conduit of course is all encompassing.

If the wall is more than 50mm thick then the rear of the cable is deemed to not need protecting.
