Swa armouring let it be Earth

[cliffed]

How come some qualified electricians will argue & argue about earthing the armouring of the cable.
Seen many jobs where they use plastic junction boxes & no earth continuity on the armouring.
Regardless of how many cores are used it still needs earthing.
Their biggest argument is it’s only for mechanical protection are they actually taught this @ College

Or the load end is converted to TT earthing system.

That is inclusive of my comment but yes I didn't specify it directly, the comment was circumstantial to not needing an earth at the load end which is inclusive of your relevent addition.
