I'm confused, is it a like a flat copper braid strap or is it armour that forms part of the incoming cable? Can you maybe post a picture?
It''s the strap from the cables lead sheath to the MET Marvo. It can either be soldered to the sheath or attached via a Hepworth or constant pressure spring clamp!! If it came with the earth clamp as part of a kit, it will generally have a 16mm CSA...
Think the other posters are getting confused between armouring and the lead sheath of a PILC older cable....
