If Apply To Generators and Recalculate Trip Time are checked, Arc Flash has two parts: one is up to generator decay time, another is what’s after, together the IE and total trip time are reported as one row, the arcing fault reported in the AF is the one before the decay so all rows belong to the same bus can be added up to the bus total. In the TCC, we are using the arcing fault before the generator decay to read the trip time.
