cable routing / perscribed zones

[lister]

Found this whilst altering a kitchen - couldnt resist a photo

Great photo mate.Should be in the hall of shame.Did you take the capping off the cable before you took the photo.Ha Ha

No capping, you can tell this by the chisel marks on the cables !!

Capping, an interesting point, I have always installed capping, i questioned it when Billy Burns of DIYSOS fame clipped his cables down the walls and they were plastered over and he was NIC approved, after a few questions I was told it wasn't a regulation, any comments

Ah, thats what they meant by a ring circuit !

As to the capping question, there is no reg as such - much like not routing cable in cavities - its more a case of good practice - lost on some folk i`m afraid.

Plus you gotta trust the plasterer has an inkling that digging his trowel into the sheath isn`t a good thing.

Keep fitting the capping lads

Its not a regulation.

The original idea to use capping was to protect the cable from the spreads trowel.

But that was in the days of render and finish. Now all the walls are plasterboard there is no risk of trowel damage.

I still use it as its easier than trying to clip the cables, especially in thermal blocks.

For the cost of it I find it so quick and easy particularly as I use metal capping, you can almost put a nail at the top and one at the bottom and job done

How do you earth it?

 

[sparks1234]

How do you earth it?

Why would you earth it

 

[Spudnik]

Because the regs say it should be?

Have alook at this from the NIC

[The Truth]

thats , there is no regulation saying steel capping should be earthed. its neither an exposed conductive part nor an extraneous conductive part. an old wives tale
MOD EDIT:NO SWEARING IN THE FORUM PLEASE

 

[electricAl]

Ummm. I may agree or otherwise, but you`re hardly in a position to swear at the person that works hardest to make this forum so good.

I suggest you tone it down or maybe this forum aint for you.

Thats THE TRUTH.

 

[Modernelectric]

if the capping is used as mechanical protection then it should be earthed.

 

[supasparxs]

Because the regs say it should be?

I understood the reg about earthed metal containment only applied if you were attempting to avoid the use of RCD/RCBO.

If the RCD/RCBO was being used then it is optional whether you used plastic, metal or no capping over the cables.

Personally I use capping as it holds the cables back out the way while all the making good is being carried out. also it will protect the cables from the plasterers trowel as previously stated.
