Earthing or bonding ?

MrJack96

I see it a lot where the SWA isn’t serving as a protective conductor which I know it must still be earthed at one end due to being an exposed conductive part. My question is if multiple SWAs are all earthed at the supply end and meet again at a bit of equipment if we then connect all the SWAs together locally is this still classed as earthing even though they are already earthed at the supply?

    The other point to consider is the conditions prevailing during service, not just at installation time. We use SWA underground because we expect that the cable could be damaged by digging tools - at which point the armour becomes exposed (perhaps as well as the digging tool itself) - whereas for plastic conduit we'd only select it if the risk of damage in the intended environment was negligible.
