Unearthed buried armour. C2 or C3

aligarjon

Hi Guys

On a domestic EICR i have come across a 3 core swa cable that loops to various points down the garden where the armour has just been cut back so obviously the armour itself is not earthed. The cable is buried.  I have initially coded it as a C2 but am doubting myself.  Is it immediately dangerous or is a C3 more appropriate.  The installation is TT with 30m/a rcd protection.

Thoughts please

    I am not sure that it is an exposed conductive part because it is buried, which is a contradiction in terms.

    I agree the wording of the definitions aren't always helpful - yet we regard a flush steel back box as being an exposed-conductive-part as well as SWA. I guess the point about SWA on a buried cable is that it's there for when a digging tool damages the cable - at that point the armour would be exposed.

    No, but as my reply to   above, a picture paints a thousand words, and in this case 's picture shows the armour is clearly visible and exposed to touch, but Chris Pearson hit the nail on the head regards armour being stripped back, revealing the bedding, or 'filler', material surrounding insulated conductors.
