Calculate the size of the CPC based on the fault current using the Adiabatic Equation!

Please note: The voltage is based on UK Voltage (230 / 400V)

Please note: Time - 0.4s and 5s has only been considered based on BS7671 for maximum disconnect times for final circuits (0.4s) and distribution circuits (5s)

Please note: Only Thermosetting cables using copper or aluminium has been used as thermosetting cables are the most common in the construction industry!
