Unearthed buried armour. C2 or C3

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 am concerned that if the armour has been stripped back in places, the outer sheath has also been removed. AFAIK, the inner sheath is not intended to be exposed to the elements. So it is not like, for example, a pond pump which is supplied with a long flex, which is intended to be submerged or buried, or a combination of the two.

    I think "improvement required' rather than "improvement recommended" so a C2 from me.

    In the pic below (which   may not have seen when he made the statement), it can clearly be seen as an exposed-conductive-part that's not only visible, but open to the touch - in fact, it would be in most installations where the armour is properly terminated in a BW or CW gland.

    I agree - and think that, worse, the inner 'sheath' is, actually, not a 'sheath' but bedding material, and therefore could be said there is no mechanical protection for the insulated conductors it surrounds ... which implies the same coding as 'I can see and touch coloured insulation of insulated and sheathed cable outside the enclosure or accessory'?
