Arc Flash

  • Major changes between 2002 and 2018
     
  • How the equations were developed and how they are applied
     
  • How to determine input values and their effects on final energies
    • Electrode geometry
    • Box sizes 
    • Gap spacing
    • Working distance
       
  • Should the IEEE-1584 or the NESC be used for these situations?
    • Enclosures
    • 1ph, 2ph, 3ph arcs
    • Open-air arcs with small gaps
    • Open-air arcs with large gaps
       
  • Model Example Systems to calculate
    • Incident energy variances based on Enclosure type
    • Worst case energy for different enclosure types
    • Arc flash boundary working distance
    • Determine new system protection schemes to minimize incident energy levels
       
  • Use the arc flash calculator for determining situation-specific energies while applying input modifications
