well, if you're depending on the armour of the cable of all that bx as a ground, you'd think there would at least be a clamp..

i see 2 NM cables with the grounding wire simply cut off..

wow, i wonder what the inspector got for this one.. it would have had to been inspected with at least that funky ground wire when the panel was installed wouldn't you think? unless they did it with the line from the meter hot as an upgrade..
