Enter Generator Data and any Motor Current Contribution from a fault condition. Calculator will generate total available fault current based on inputs.

Enter Incoming Supply values and any motor contribution to total Available Fault Current

Enter Transformer Basic Data. Select Transformer Primary source data from utility. Motor contribution can also be inserted for total Available fault current calculation.

Use radial selection buttons to insert the Voltage and Fault Current associated with the source tab you want to use.

Enter the length and cable configuration from Source to the First Breaker. Select the wireway type . Enter same information for Downstream breakers.

Select Equipment Type. Available Fault Current will automatically calculate the FC at the breaker connection based on cable resistance. Enter breaker Clearing Time based on TCC and Incident Energy will compute. Make same entries for downstream breakers, if needed.
