Welcome to the forum.
Is what correct? What's your question?

We would not be allowed to use that EG bond on a 4" square raised cover. Not sure about your situation.
I certainly would not want to be holding that barehanded under the 'wrong conditions'.

'20 NEC 250.146
250.148(B) is closer.
250.148(B) is closer.
Not sure what I'm looking at exactly (panel mounted single phase outlets?) but my first thought is that it seems to be missing a bonding jumper to the frame of the equipment to which to EGC would be connected, which to ptonsparky's point would mean a nasty shock if one of those hot conductors shorts to the metal plane you're holding.

Those appear to be factory installed, so NEC is probably not applicable. But as others have said, it does not appear to have a bond jumper from the equipment to the panel. But that being said, if the panel is not hinged, a cover screw should be marked as ground, along with a star washer insuring a bonding path.

I agree, looks like it's integral to a piece of listed equipment so the NEC does not apply.

So we're talking about the EGCs. Aren't the receptacles' EGCs tied to the yokes?
I agree that the panel should have a jumper to the enclosure.

I see nothing wrong with your hard hat on the floor mines there all the time. Or do you mean the device make up.
The one wire looks a little discolored. Maybe a loose connection there.

If you are concerned about sharing a neutral it is often done but we are all guessing here.

Yeah, looks like they are using it as a multi wire circuit, bet it’s single pole breakers, and since it is a manufacturer, they don’t have to use handle ties.

My bigger concern with the MWBC aspect is they using the devices to splice the neutral. As said this probably not subject to NEC, but if it were it would need a pigtail to each device instead of a jumper between devices. 4th device has separate neutral to it, but that would be outside the "MWBC" supplying the other three devices so makes sense there.
I was wondering about the ground and neutral jumping. This is a container being used for servers. The customer was wondering if it was up to code. All I know is that has a UIL sticker on the structure. Will try and find out more. Thank

Again this likely part of something not covered by NEC, but if so continuity of EGC can not be interrupted by removal of a device.
