armoured cable should it be earthed

mcfcdwa · Oct 30, 2011

hi everyone first message on here, im sure it is simple to mst people,i need to know if the outer metal strands on an armoured cable MUST be earthed. it is from the board to a garage at the bottom of the garden and the earth is run in the black cable, neutral in grey and live in brown or red cant remember

the armour must be earthed at the source,as it is an exposed conductive part.whether it is used as earth for the installation it supplies is another matter

Yes, It should always be connected to an earthing terminal, but does not necessarily need to be connected at both ends.

thankyou for your reply.so it can be earthed from the garage end as it has been stripped back at the source end to fit it into trunking

It can still be earthed at that end.
You would use an SWA gland, and then connect an earth conductor to the gland.
