I was told there were not problems with this panel.

Can I have some industry support to confirm my concerns with this unsafe panel converted to pull box with two different voltages and shared neutrals?

What problems concern you?

 

[K8MHZ]

It looks like most of the panel has been removed from the enclosure and the bare bus bars taped with black tape. I also see what looks like brown wire going to the neutral bar, it's hard to tell from the pic.

I don't think the tape qualifies as a 'legal' form of insulation. So I would be looking into that. The ground lug at the bottom may not be rated for multiple conductors, but that's not as scary to me as the black tape on the bus bars.

The best I could see of the labels read 'Automatic Tripped Indication'

So, breakers were once in that enclosure.

120/208 in same raceways as 277/480. Shared neutrals between the systems, solid wire butt splices. My secondary 120/208 transformer has a shared neutral with 277/480 so when a lighting circuit trips, it shuts down my whole 120/208 branch circuit. The taped buss ways are definitely dangerous. This exists at a hospital so it's very dangerous for the applications.

As stated in your duplicate thread, this is not a code violation and neither are the butt splices

Butt splice and heat shrink the feeder conductors, remove the buss bars, have a new panel cover made, its now a junction box

What about the brown wires?

 

[K8MHZ]

It's not clear, but it also looks like the neutral bus is electrically connected to the enclosure. If so, an isolated neutral bar needs to be installed.

I don't think they are brown...i think that is just old white RHW.

Not a code issue.

Shared neutrals between the systems

That would be an isssue,

solid wire butt splices.

Most crimps are listed for use with both solid and stranded conductors.

I don't understand how that can happen. There is something else going on.

The taped buss ways are definitely dangerous.

They are in an enclosure...I don't see an issue.

This exists at a hospital so it's very dangerous for the applications.

The only real issue is if the neutral is really a common neutral for two different voltage systems.

OP said they were brown in the other thread. But they could be aged brown as opposed to manufactured brown.

This could be true. The system is old.

 

[GoldDigger]

A shared neutral should not cause one system trip to kill the others, unless your breaker interrupts the neutral. That would be a very bad idea.
If you mean that the loss of the primary supply kills the secondary, that is unavoidable.

I agree, most other items mentioned are NEC compliant or very easy and not much expense to fix.
