Several overlapping issues.

The image of the unwrapped
compression connection
looks to be the neutral conductor.

The feed looks to be (3) insulated
wires and one bare stranded
“ shield “ wire that has been
twisted and utilized as an
equipment ground for a
sub panel feed in a sheathed
cable.

This sheathed cable is a
wiring method intended
to be used above ground
in spaces not subject to
physical damage and
ran in the building framework
like romex wire.

It is not intended to be
installed in a raceway
or underground as
a direct burial cable.
