- 13 -

8.12.6. The short-circuit calculations and the corresponding incident energycalculations for all operating scenarios must be compared and the greatestincident energy must be uniquely reported for each equipment location.Calculations must be performed to represent the maximum and minimumcontributions of fault current magnitude for all operating conditions. Theminimum calculation will assume that the utility contribution is at aminimum and will assume a minimum motor contribution (all motors off).Conversely, the maximum calculation will assume a maximum contributionfrom the utility and will assume the maximum amount of motors to beoperating.

8.12.7. The incident energy calculations must consider the accumulation ofenergy overtime when performing arc flash calculations on buses withmultiple sources. Interactive calculations must take into account thechanging current contributions, as the sources are interrupted ordecremented with time. Fault contribution from motors and generatorsshould be decremented as follows:

8.12.7.1. Fault contribution from induction motors should not beconsidered beyond 5 cycles.

8.12.7.2. Fault contribution from synchronous motors and generatorsshould be decayed to match the actual decrement of each as closely aspossible.

8.12.8. For each equipment location with a separately enclosed main device(where there is adequate separation between the line side terminals of themain protective device and the work location), calculations for incidentenergy and flash protection boundary shall include both the line side of themain breaker and the downstream bus.

8.12.9. When performing incident energy calculations the line sideand load side contributions must be included in the calculation.

8.12.9.1. Mis-coordination cai be checked amongst devices within thebranch containing the immediate protective device upstream of thecalculation location and the calculation can utilize the fastest deviceto compute the incident energy for the corresponding location, andthe number of levels shall be subject to the judgement of theengineer.

8.12.9.2. Arc Flash calculations shall be based on actualovercurent protective device clearing time. Maximum clearing timewill be capped at 2 seconds based on IEEE 1584-2002 section 8.1.2.Where it is not physically possible to move outside of the flashprotection boundary in less than 2 seconds during an arc flash event, aclearing time based on the specific location shalt be utilized.
