SWA glanded in a plastic stuffing gland

Davey

Hi all, 

I’ve been trying to settle a difference of opinion and looking for advice. 
we have several supplies fed in SWA, they have all been glanded off with a CW gland into the DB. At the load end, the armouring has been taped up and a plastic stuffing gland has been used where it enters  metal EV Chargers, its been done deliberately to isolate the earth to the chargers. 
My colleague and I think this is poor practice and think an isolating gland should have been fitted or the armoured terminated into a plastic enclosure prior to entering the charger. the below regulations are what we believe are contravened. 

Regulation 134.1.1Good workmanship by competent persons or persons under their supervision and proper materials shall be used in the erection of the electrical installation.

regulation 526.8 Cores of sheathed cables from which the sheath has been removed and non-sheathed cables at the
termination of conduit, ducting or trunking shall be enclosed as required by Regulation 526.5.

Our colleagues think we are incorrect, yet have conceded that the use of a stuffing gland isn’t to manufacturers instructions and agree that the stuffing gland isn’t supporting the cable like a SWA glad would by clamping the armour.

what is everyone’s view on here?

    Hi Davey. Is  the SWA cable a three-core type? Should the earth be isolated from the chargers, or is it possible that Black core is being used as the circuit protective conductor and the armouring is being earthed at the distribution board end, considering it is classified as an exposed conductive part? Or is it because you are converting to a TT earthing system at the charger?

    Hi AMK, one of the cores is being used from a O-Pen device, the armouring is being isolated at the point of the charger so that O-pen Earth is kept seperate from the earth of the electrical installation.

    My issue is the use of the stuffing gland and that SWA is made off correctly.
