metal capping not needed according to 17th

[Ryan O'Toole]

Is metal capping required on a new installation in a house to protect the cables if a rcd is used ? According to two lads who i work with have done there 17th ed last week it is not needed so is it only for protexting cables while been plastered ?

It is not required. Favoured,specified,preferred,but not required. Careful plasterers negate its use...:icon12:

Never has been "required", but good practice to avoid cable damage from flying plasterers!

 

[Ryan O'Toole]

So its not a requirement but more to stop any damage while been plastered so doesnt really offer mexhanical protection when plastered

As already said, never required but often used.
It cannot be used as mechanical protection for the cables if not RCD protected and buried less than 50mm

Yep. Never has been required. Is not classed as mechanical protection.

if someone was to bang a nail the capping wont help. but it will make extracting the cable for repair much harder.
i`m filling my chases with some bonding coat, no cables on show when plasterer comes do his job, no problems later.

That's what I do on the very few domestic jobs I do/ have done.

capping is pointless really, but is something most electricians like myself like to do.
i thought there was once a reg, for reasonable protection from the plasterers trowel.

I always thought it was a rule of thumb or best practice, If the width of the chase is greater than 3/4 of the width of the plasters trowel capping is needed???

It would be wise to use plastic capping on bare inners leafs that are going to be floated. It keeps the cables tidy and together (if there is more than one) and gives enough protection against a trowel, its common sense really.

Are you in Training?

Sorry...

We always install capping when we wire in singles however.

Singles require a proper containment system!!
