PFC prospective fault current calculator, calculate the kA PFC fault current from the other known units of voltage and Zs, Ze or Zdb values.

• Volts (voltage)
• Zs, Ze or Zdb (ohms)
• PFC  = Prospective Fault Current (kA)
• PEFC = Prospective Earth Fault Current (kA)
• PSCC = Prospective Short Circuit Current (kA)

1kA = 1000 Amps, 0.5kA = 500 Amps, 0.07kA = 70 Amps.
