Switchboard Rating for Internal Arcing Fault and Peak Current Withstand

Many Electrical Engineers put "20kA @ 0.2s" ratings on the switchboards they are designing but they do not know how to calculate the rating or why they need to include the rating in their switchboard specification.

This is a sad and dangerous reality but even seasoned Electrical Engineers are not doing this calculation. It is either, they just copy whatever has been previously designed or worst, they are just doing guess works.

The purpose of this paper is to enable Electrical Engineers to calculate the Internal Arcing Fault Clearing Time and Peak Current Withstand of any switchboard they are assigned to design.
