Earthing metal capping?

[festa]

As the headline says really ....how do you earth your metal capping?
Are there any special products out there to do this ?

No need

So if the capping was touching,say a metal backbox and a fault developed causing the capping to become live it would not be a problem?
Cheers for the reply by the way

Well for a start the metal back-box should be earthed so if a fault developed the supply would be cut anyway.

Capping is generally used to protect cables from crazy plasterers. Since plaster isn't conductive (when its dry at least) there isn't a problem with it becoming live as it isn't accessible to touch.

Are you confusing capping with conduit? Are you running the cables in the safe zones or do the cables need mechanical protection?

The metal box would be earthed, so the protective device should operate

Its not a job im doing but just reading about it and couldnt find regs on it having to be earthed so was just wondering.

Thanks very much.

Earthing metal capping?

No, no, no, no, no, no, NO!

Why, oh why, do people get so confused about this?
