At least they used bushing these guys didnt but it was only on the 208 side of the transformer. The new tenant didnt need the transformer for what they where doing so I just disconnected it and let the owner decide what he wanted to do.

That's an interesting one. I see an EGC, so I assume the fault occurred inside the flex itself, and the connections were high enough impedance that the breaker took forever to clear it?
Fault happened at the other connector inside the panel that I didnt take a picture of. No bushing on that side either, insulation rubbed through and it was over. Happened at night when no one was in the warehouse not sure how long it took the breaker to clear but it did trip. Not till everything melted though.
