capping

[Buzz-light-bulb]

Does anyone know anywhere in the regulations that it states I have to use capping to protect cables when embedded in plaster as I am currently on a rewire, it says in on site guide that if there's no rcd protection it does require metal earthed capping

Hows the crimp fastened to the capping though?

screw or nut and bolt if I'm felling particularly fancy.

Inaccessible joint?

But that introduces a earth potential where its not needed

id say its better to create that earth potential than installing a full length of capping that could potentially become live ?

How can it come live?

No electrical connections contained within it? Is there!!!!!

Inaccessible joint of what...capping to brick ? joint of cable to capping is crimped.

We aren't under the 15 or early 16th editions anymore lol

Large piece of unearthed capping in the wall....lady puts picture up.....nail through capping and through live core only...full length of capping is live and no trip.......thats bad.

Earth terminal fastened to capping via nut and bolt which is then buried in plaster. At least I think that's what you mean.

clipping every cable with T&E clips?

How are your cables supported then if they're not clipped?

I just think its good practice.

You not heard of safe zones?

Don't forget to run a fly lead from your capping to the metal window frame.

I think its ok to drive my vehicle after 5 pints, doesn't make it right does it?

 

[DPG]

At the risk of being facetious, I'd say don't earth your capping, then get your rewires done even quicker. You do take a while. Daz

we have, but silly moo nailing up a picture usually has no idea. she thinks the electricity gets to the socket by magic.

 

[Plonker 3]

How far do we go to make things safe from silly moo though?

Surface everything in the next update anyone? lol

I was taught to always earth capping..old company still does it. Safe zones yeah but what if you install and a sharp edge of caping has sliced into a cable by accident ? you have just installed a large piece of metal in the wall that is now live...I earth it then I know I don't have that problem as any contact to live will also be to earth and trip.

I think it was councils who insisted on this even when not required..but Ive always just thought it was good practise too ! Id rather do that than potentially make a wall live, not know till someone soaks it with paint and gets plated.

The roll of tape every foot, gentle pressure of the capping , bonding coat and finish coat usually support them well enough ...

i use plastic oval tube. hate capping. either the nails won't go in or they fall out as soon as you let go.

who's next ?
