Cables and cavity walls

[Spoon]

Does the OSG reference a Regulation?

It only has 522.8 at the top of the page, mate.
No actual max length stated in 522.8.

Think that was meant to be within?

You made a mistake and got something wrong!

Nope, it was autocorrect.

There are different rules for caravans, because they’re transportable, though the 400mm figure is for accessible cables.
It’s also unlikely that you would have a caravan where you could have a vertical run of 5m.

Yeah mate. I just put the 721.522.8.1.3 reg down as that was the only reg I could find that actually stipulated a length.

Recently got the BBB and OSG. Ripped them to bits and scanned/OCR both of them... Makes them a lot easier to search.

Does the program read all the words correctly?

Use Nitro Pro 10. Haven't had much of a problem with it up to now.

Can you use it on PDFs you already have, or must you scan the document using the program?

You can use it on PDF's you already have.
I think you have to pay for it, as there is a licence...

If you need anything doing then, seeing that it's you, you could email it to me and I will OCR it. Then you can see what you think of it before hand.

I have Adobe Acrobat.
Just seems a bit clunky.

 

[Spoon]

Nitro Pro 10 is just what we have at work so I use it. Seems good.

Pheeww, thank God for that.

If you are having problems with a PDF then I can OCR it with Nitro, if you want. See if its better..

Cables in external cavity walls are not allowed. Another reason why not, is that a 3rd party might hit them when drilling through wall to install TV cables etc

 

[westward10]

And they wouldn't hit them if they were chased instead?

Can you give a reg number for that mate?
Would someone drill through the full width of a brick (102mm) to fix a TV cable?

 

[Midwest]

I doubt if you could find a BS7671 reg or Building Reg against it. But if its at all possible, a cavity is not the place for any cable, unless its straight through or less than a couple of meters, aka meter tails etc.

That's what zones of protection are for

Prescribed routes.
You don’t think there would be a prescribed route if the cable were in the cavity?
You should also consider what happens to loose cables when drilled as opposed to captive cables.

 

[Midwest]

Thats that then. New builds should have all the cables run in the cavity, wouldn't have to worry about sheathing or clipping the cables.
