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.

    I am confused! So this “filler” that surrounds the wire armour is of insufficient construction to regard the wire armour as not being an exposed conductive part. OK, let’s accept that argument, so it is an exposed conductive part. Does that mean that we have an issue with all those early EVSE points wired in SWA with the wire armour connected to the PME terminal but separated from the TT earth at the EVSE as we are breaching 411.3.1.1?
