I was reading a recent post re the purpose of glands when connecting SWA to a CU.
This got me thinking. My brother has got a 2.5mm T&E spurring off the back of a socket into an external JB connected to armoured cable via a 30a chock block. All cables are connected like for like (L -L,N-N,E-E). The armour of the cable isnt earthed to anything and instead of the metal (copper) type of gland he has a plastic one (which the armour tightens into).
This sounds as if its not acceptable presumably because if the armour became live it has no path to earth (despite that fact that its buried in the earth). Am I right? Does he need to add a gland and earth it to the armour?
