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

    The only proviso is that there is some sort of earth connection by it reaches the load - if the TT earth is not getting to the end of the cable then that is a bit more serious. Then a clear C2 - lack of earth is not immediate danger like a live part exposed and in reach,  just removal of ADS - so a single fault may not clear.

    As a side thought how would we feel if a non-armoured cable had been buried, because in effect it has, or at least a large part of the benefit from armour is lost - there are probably situations where that is OK, but it does not feel good.

    This cable loops to various points down the garden, it finished in a shed where it was connected to a socket where the live and earth were reversed. Probably a good job the armour wasn't connected.  I think Slight smile
