I would say that unless strictly prohibited ALWAYS earth it after all its in very close proximity to live conductors and if someone slices thru the cable by accident it lessens the chances of the person getting a fatal shock. Case in point my dad sliced thru an swa cable whilst making holes for fence posts he didn't feel a thing but it took out all 3 of the main fuses for the building
Quite right Kelly, I always earth the armour of any underground mains S.W.A. cable for safety reasons. I recently came upon a customer that had had a new fence installed. A Metpost had pierced the S.W.A. cable underground but the circuit protective device tripped off thus preventing danger in the garden. Just think of a dog peeing up a live Metpost, or a child retrieving a lost ball by the Metpost. Not nice.
