Rich asks this question, which concerns whether the braided link for steel wire armoured (SWA) cable glands should be terminated onto the CPC? It has been answered by the NICEIC (Theme - Cables):
Question: To settle a debate, should the braided link for SWA glands be terminated onto the CPC? I say ‘yes’, but the person carrying out the work claims that the armouring is only for mechanical protection and does not need connecting to the CPC. Who is correct?
Answer: The armour of a SWA cable should always be earthed where fault protection is provided by the measure Automatic Disconnection of Supply.
Where the SWA is not employed as a circuit protective conductor, it should be considered as an exposed-conductive-part.
In either situation, the SWA should be effectively earthed - and where a gland is used, it should be installed to manufacturer's instructions.
