I find that underground strip-armoiured,4core,LT PVC cables in an earthed power distribution sytem are occasionly found in charred condition-with no trace of it except ash. Is this because of no proper earth connection/continuity (giving rising to high armour resistance)in the joint enroute or because of insufficient capability (again due to high armour resistance)of cable-armour to carry fault current or due to neglected /unprotected overloading of the cable or due to high armour currents caused by power thefts where only phase(s) are unauthorisely tapped & at the point of poer consumption earth terminal is established by burring underground a not so good earthing rod (or using an underground water pipe for the purpose)
