I am reviewing an Arc Flash study which was done for our plant. Each of the pieces of equipment (Switchgar, MCC's, etc..) are labeled with their corrosponding Arc Flash rating category 1-4.
Some equipment has the category level listed as "Dangerous" I was not sure what this dangerous level exactly meant. Does this mean that this equipment was above all Arc Flash categories and could not be worked on hot? Is there a standard understanding of this term "dangerous" or is this user defined by the individual performing the study?
