OK I have since talked to the person who sent me these pictures.

This is / was a 600 amp GE panel.

The person who sent me the pictures had nothing to do with the damage and the contractor responsible for this was very tight lipped.

We have a long standing maintenance contract with this customer, they put some work out to bid and the EC that got that work did this.

Once that happened we where called in to fix it.

Our guy is fairly certain a metal snake was sent into the live panel, the outer cover was off but the dead front was in place.

As far as he could find out the person in front of the panel was OK but a little dazed.

Bjarney, you are right, this is a good reminder of the invisible but potent force we deal with.

Yeah, sure.

You are right but that is standard installation practice in this area.

If someone is in this panel and thinks the white conductor on that breaker is grounded they probably have no business in a 480 volt 600 amp panel.

In this state the NEC was also amened so that we do not have to re-identify whites in cables used as hots for switch legs.

Be Careful out there.

I wonder if faults like this are "louder" than single ø-g(n) faults. From the cinders, there may have been flashes almost simultaneously on Cø-G(N), Bø-G(N) and Bø-Cø. The fish paper does indeed look a little worse for wear.

That'll get your panties in a bunch. ;-)

Panties in a bunch? More like skidmarks in the shorts.
