S.W.A. Armour Earthing.

Zoomup
Which regulations(s) require the steel wire armouring of a S.W.A. cable to be earthed if it is NOT used as a circuit protective conductor?


Case 1. Cable buried underground.


Case 2. Cable NOT buried underground.

    Two simultaneously-accessible "earth" potentials. "just not exposed to touch when the box is shut."

    Inside an enclosure is perfectly OK for bare hazardous live conductors - are you really suggesting we need to go further for differing Earthed conductors?
