I see this a lot on sites where they’ve got an armoured cable with an earthing ring/banjo connecting the armour to an extraneous conductive part. Should there also be main bonding run as well? Common thing I see is cable tray being supplementary bonded of a local isolator usually 6mm or 10mm?
If the daisy chaining is done at the isolator (connecting the swa together with 4mm)should we then connect that to the earthing terminal at the isolator?
