Don’t assume compliance has been achieved, get the PFC Calculator and be sure

PFC or Prospective Fault Current is a term used to describe the higher of either the prospective earth fault current (PEFC) and prospective short circuit current (PSCC).
Calculate the PFC fault current (kA & Amps) single phase and three phase PFC from the voltage and Ze or Zs earth loop impedance values.
