Can someone clear up a confusion of mine please:
- if this SWA was a regular T&E in copex, I assume that the earth core along with the RCD will provide protection from someone drilling into the cable or forking into it?
- The SWA also has an Earth core and will be continued through the SWA legs as I will be wago’ing them across. At this point I’m thinking, how is it different to the above scenario…
Is the additional concern the metal protective strands of the SWA? Do these also need earthing and continuity? Is this what is done through a metal gland and the earth nuts?
Thanks again
Have you not read the replies?
Yes the armour must be earthed continuously for reasons outlined above. The brass parts of the glands are used to maintain this and banjos would be bolted together (or connected through a fly lead) for this reason.
