capping

[telectrix]

and much of this is now in metal studding, so 522.6.103 applies.

 

[Guest569]

SO whats the verdict ? Better to earth the capping or not ?

Since we like to get involved in IFs and BUTs around here, its perfectly reasonable to expect a cable to be sliced or damaged by capping during installation occasionally....When I have guys working with me how am I to know exactly how they have installed things ?

Id rather have it earthed than walk away from a job leaving someones wall live , with no way of knowing till you touch it !

And to confirm, Im well aware capping is NOT mechanical protection.

Bonkers.

The simple solution if you are determined to use capping to aide in the installation of cables/protect them from the plasterers trowel is to use plastic capping! Metal capping is a silly idea IMHO.

I do use plastic where possible but for longer chases with more cables Ill use metal purely as its easier and quicker in this situation as its more ridged.

So is the consensus that I should stop earth metal capping ? Is this acceptable and do the majority of folk do this ?

 

[D Skelton]

Why bother with capping at all would be my question?

 

[DPG]

Agree with Mr. Skelton. Seems mad to earth all capping when you could just use plastic. Daz

Thought you were in favour of the silly metal capping and earthing regime.

Plastic is ok until the cold weather sets in and it cracks when trying to cut it and fix it.

I agree. It's not needed on rewires and most domestic jobs now entail dot and dab so the plater never goes anywhere near the cable with their trowel.

Where did I say that?

I was using the principals of automatic disconnection of supply to discuss the use of metal capping from a purely regulatory point of view.

Most domestic jobs entail dot and dab ? .....not where Im from.

 

[Guest569]

personally I think twin and earth clipped in a bare raggle looks pretty rough....yes it complies with regs but I just think it looks a bit DIY. Capping is much neater job.

Tel had this topic nailed 2 days ago, post 59!
Easier, rewireable, ...
+1 here.

I think you will find on new builds it is. Obviously not possible on rewires, which seems to be the brunt of your business

Once it's plastered over, can't see what difference it makes how it's installed as long as it complies with BS7671

on domestics i use pvc oval tube for 2 reasons.

1. clips are plugged and screwed. no chance of bashing your left mitt with the hammer.

2. if some numpty does drill/nail a cable, it's easy to rewire the drop. also, on switch drops, as long as the tube is big enough, it.s easty to draw in another cable when customer decides they want another set of lights fitting.

Unless they leave the nail in

 

[SparkyJoe]

You could realistically say the same for SWA cable that's been imbedded in a wall or whatever. The SWA isn't going to stop a nail either, but it doesn't require RCD protection!!

Apart form the fact that if you smash a nail into a live conductor on a swa, your breakers going to trip, where as if you smash a nail into the live side of some T&E covered by metal capping, **** all is going to happen. (RCD's aside)

Neat bit of capping would look miles better and take half the time

We'll just have to agree to disagree there then!

He said most "most domestic jobs" not "new build domestic" ...read the post ..if i posted that you would be jumping on it.

Your second comments pretty contradicting to your usual posts ...I could install plenty of stuff that complies but looks like ****.....but whens its plastered over who cares ? you have changed your tune.

Sorry to clarify, I meant weather it is clipped or capped. Never going to be seen again is it?

I know what he wrote, I was just trying to explain it. As I put it's pretty obvious you won't dot and dab a rewire unless the house is gutted.

Yeah well for me clips look crap...capping is much better to look at. Same reason my consumer units are tidy, you don't see a thing when the covers on. Its called pride in work.

 

[Plonker 3]

Can't say I get off looking at either capping or clips, but each to their own I suppose

I was on about new build jobs mainly use dot and dab. Like I said I would not generally use capping on re wires as its often not required.

Looks good. Should have used a stanley knife to score the edge of the channel though so it wouldn't cause the paint to chip and leave rough edges.

what?? have you seen the price of stanley blades?

 

[Plonker 3]

That's why you borrow someone else's to do it.

If I remember right, loop in, loop out, circuit one, circuit two, circuit three, two way for circuit three

Doesn't bother him in the slightest!

Skim coat is far easier to blend into a rough edge as opposed to a neat one

 

[nickblake]

I will always use capping regardless of whether its needed or notfor me its a better job and i use an impact driver and screw into the joints between the bricks works a treat

In some houses screwing straight into the cement between brick works great too.

edit just read your post through again "joints" between brick. Yeah does work well !

****ed is the new straight

 

[D Skelton]

Must be your eyes mate, it's perfectly straight.

 

[SPARTYKUS]

Capping cables regardless of need takes longer & costs more.

so thats for a rich man with loads of time.

Dot & Dabs, never bother. Spreads trowel will never see the cable.

The chase I meant

 

[D Skelton]

Oh right, doesn't seem too bad considering we use channelling chisels and not wall chasers

 

[telectrix]

nothing wrong with that chase. it's the wide-angle lens makes everything look pi$$ed. ask tony. he's a photography expert.

clue. perspective and distorted verticals.

 

[nickblake]

one of the reasons i use capping is it is possible to replace the cables after how many rewires have you done when you can pull the old wire out and replace them ,did one a few weeks ago guy had drilled through the cable and bodged the repair was able to pull out the damaged cables and replace them , you cant do that if they are plastered in , it was either chase the full wall out or a 3 inch round patch , when you look at costs , half hour to replace the cables completely down the wall or 2 hours to chase and patch redecorate

 

[telectrix]

not always possible with capping if the wall is uneven. bound to be a tight bit or two. that's another + for tube.

 

[nickblake]

love the tube its all been done in the houses in valley houses so easy to pull new cables in

 

[jeremy]

You also have the issue from penetration from the other side of the wall. Capping doesn't protect from that does it?

Something Berlin prostitutes worried about for years
