Panels do not have ratings of this nature. Panels are rated for the maximum voltage that can be applied, for the maximum continuous current they can handle, and the maximum fault current they can take, but not for the amount of arc flash energy they can release or they can survive. But if you are asking what information should be placed on the arc flash label, or what PPE must be worn in order to perform live work on the panel, then I refer you back to Zog's answer.. . . cal per cm squared rating. . .
I am doing a Arc flash hazard assesment and i need to know if any one knows how to
get the cal/cm2 flash hazard at 18 " on a 480v 2000 amp mdp

Yes, I know how to do it. I would start by opening up the company?s licensed copy of the SKM Power Tools software. I would create a model of the electrical distribution system, including the utility transformer, the service conductors, the panels and transformers throughout the facility, and the feeders connecting all components. I would input the conductor lengths and wire sizes for all feeders. I would input the model numbers and trip settings of all overcurrent devices. And I would input the horsepower and other ratings for all large motors installed in the facility. Then I would review the data, to see if I have missed anything. Next, I would hit the ?Arc Flash Analysis ? Go? button, and print the results. Then I would review the results to verify that they appear to be consistent with the input data. Finally, I would write a report that documents the entire process, and apply my PE seal and signature to the document. Oh, actually, that would not be the final step. I would still have to send the invoice for my work.. . . I need to know if any one knows how to get the cal/cm2 flash hazard at 18 " on a 480v 2000 amp mdp
But that's because you understand the arc flash hazard problem and the analysis. I would not suggest that the OP buy SKM and attempt this on his own without enough study to understand what he's doing.Yes, I know how to do it.
