Add excel to deliverables Arc Flash Hazard Analysis: The arc flash hazard analysis shall be performed according to the IEEE Std. 1584-2002. These equations can also be found in NFPA 70E (2018), Annex D. The flash protection boundary and the Incident Energy shall be calculated at all equipment locations referenced in IV. The Arc-Flash Hazard Analysis shall include all significant locations in 240 volt and 208-volt systems fed from transformers equal to or greater than 125 kVA where work could be performed on energized parts. Safe working distances shall be based upon the calculated arc flash boundary considering Incident Energy of 1.2 cal/cm2. When appropriate, the Short Circuit calculations and the clearing times of the phase overcurrent devices will be retrieved from the Short-Circuit and Coordination Study model. Ground overcurrent relays should not be taken into consideration when determining the clearing time when performing Incident Energy calculations The short-circuit calculations and the corresponding Incident Energy calculations for multiple system scenarios shall be compared and the greatest Incident Energy must be uniquely reported for each equipment location. Calculations must be performed to represent the maximum and minimum contributions of fault current magnitude for all normal and emergency operating conditions. The minimum calculation will assume that the utility contribution is at a minimum and will assume a minimum motor contribution (all motors off). Conversely, the maximum calculation will assume a maximum contribution from the utility and will assume the maximum quantity of motors to be operating. Calculations shall take into consideration the parallel operation of synchronous generators with the electric utility, where applicable. The Incident Energy calculations must consider the accumulation of energy over time when performing arc flash calculations on buses with multiple sources. Iterative calculations must take into account the changing current contributions, as the sources are interrupted or decremented with time. Fault contribution from motors and generators should be decremented as follows: Fault contribution from induction motors should not be considered beyond 3-5 cycles. Fault contribution from synchronous motors and generators should be decayed to match the actual decrement of each as closely as possible (e.g., contributions from permanent magnet generators will typically decay from 10 per unit to 3 per unit after 10 cycles). Each equipment location with a separately enclosed main device (where there is adequate separation between the line side terminals of the main protective device and the work location), calculations for Incident Energy and flash protection boundary shall include both the line and load side of the main breaker. When performing Incident Energy calculations on the line side of a main breaker (as required per above), the line side and load side contributions must be included in the fault calculation. Mis-coordination should be checked amongst all devices within the branch containing the immediate protective device upstream of the calculation location and the calculation should utilize the fastest device to compute the Incident Energy for the corresponding location. Arc Flash calculations shall be based on actual overcurrent protective device clearing time. Maximum clearing time will be capped at 2 seconds based on IEEE Std. 1584-2002 section B.1.2. Where it is not physically possible to move outside of the flash protection boundary in less than 2 seconds during an arc flash event, a maximum clearing time based on the specific location shall be utilized.
