Hello, could you explain what I should do with this error?
"The tripping time of the protective device exceeds the required disconnecting time for earth fault currents. However, the distribution board is specified to be equipped with equipotential bonding, thereby fulfilling the requirement for fault protection.
The tripping time of the protective device for fault currents exceeds 5s."
And I need to use 1250A breaker, cable max load is 1300A, when I'm using it, I'm getting this error "The protective device is not disconnecting the fault current(s) fast enough due to the heating of the cable/busbar."
