Joe,
I did submit a comment on this issue when it was proposed for the '02 code. The original proposal called for the field applied label to contain that actual arc fault information. My comment was opposed based on two things. First, such calcualted values may not be valid in the future and if too low could lead someone to not use enough PPE. Second, the only people that would know what this label means, are people who already know what types of PPE are required. At this point, where no calculations are required to be posted, I fail to understand why the rule requires a field applied label. Why not just have the manufacturer apply the label when the product is made?
