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
 
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.

never seen u earthing ur capping on that youtube vid
 
Lets all take a deep breath and....... relax :)

Now.. Biff, say you're sorry and shake hands, you'll only regret it in the morning when you're sober!
 
Perhaps if you used the correct size capping for the number of cables installed and took your time instead if being a rough a*/'e then there should not be any concern about nicking a cable.

Also two lengths of capping is not a substitute for metallic earthed conduit. If it was deemed acceptable it would state in the regs earthed metallic conduit or similar but it doesn't.
 
yes, but then cables > 50mm deep would be at risk and they don't require any protection. you get builders and wood butchers around, anything can happen, but how far do you go?
 
Yeah sorry I was thinking about zones.
'A zone formed on one side of a partition wall of 100mm or less thickness extends to the reverse side only if the location of the accessory can be determined from the reverse side'

Think about it for a minute now would ya. What purpose does an earthed metallic sheath serve in a cable? Why would an earthed metallic length of capping be any different to this? We all know it isn't mentioned in the regs, but we're talking theoretically here right.
 
So would it be fair to say that if it isn't listed as a method of providing penetration protection the same as an earthed metallic sheath, but, it is as safe as, then it could be listed as a departure from BS7671?

Because capping does not fully enclose the cable nor is it in direct contact with the cpc

You are relying on an the capping being suitably earthed and without this connection being accessible for verification I would not deem it as acceptable. I could probably ask someone to give me a number of reasonably qualified reasons why earthing a piece of capping does not constitute as suitable protection but i have others things to do.

Unless the wall is so thin that the distance between the cable and the other side of the wall is less than 50mm then the cable doesn't need to be enclosed. Also, if the capping is earthed then of course it is in direct contact with the cpc.
