Low voltage box/MCC with all parameters given, moderate fault levels
Incident Energy
Calculates arc flash incident energy, arcing current, arc flash boundary distance, and required PPE category using the IEEE 1584-2002 empirical method for systems from 208 V to 15 kV. Models both low-voltage and medium-voltage arcing current equations and normalized energy formulas, supporting electrical safety assessments and arc flash labelling per NFPA 70E.
