4.0 Tips for calculator useSTEP 1: Perform Short Circuit Analysis1) Short circuit analysis is beyond the scope of this calculator. It is the user’s responsibility to obtain the short circuit current.2) Since the level of the short circuit current configuration is a crucial dependent, the user may want to investigate possible short circuit current with different system configurations.STEP 2: Determine the Configuration1) This calculator offers five (5) different electrodes configurations (VCB, VCBB, VOA, HCB, and HOA) for arcing current, incident energy, and protection boundary estimation.2) It is the user’s responsibility to determine which configuration best resembles the studied system. IEEE Std1584-2018 provides guidelines for the selection process.3) Trajectory of the plasma is one of the most important factors to select in the configuration. The user can refer to the following figure (Righthand rule) to determine the trajectory of the plasma where “B” is the flux, “I” is the arcing current, and “F” is the direction of the force.4) Based upon the system configuration and equipment arrangement, it is the responsibility of the user to determine where the arc flash incident may happen.
