Hi guys. All of the equipment under 600V specifies what fault current and clearing time were used to determine the hazard categories in the table by referencing a note shown at the end of the table.

However, all of the medium voltage tables for equipment over 600V has no mention of a note. Does anyone know what values where used to determine the hazard categories shown in the table for MV equipment? I don't see how you can use the table for MV equipment if you can't confirm that your specific fault current and clearing time is less than the value they used. I have searched through the code and have been unsuccesful in finging anything.

If anyone can enlighten me I would appreciate it.
