Step 5: Arc Flash Calculations
These calculations are primarily based on available short circuit present, protective device clearing time and distance from the arc. Calculations of incident energy ranges and flash safety boundaries will probably be completed for all relevant equipment busses. The magnitude of arc hazards are determined using methods from NFPA 70E, IEEE 1584 or NESC Tables 410-1 and 410-2, as applicable.
