If a feeder circuit-breaker trips what action is required, Electrical Engineering

Q. If a feeder circuit-breaker trips, what action is needed?

Ans: First isolate the faulty feeder check the faulty area on which fault the breaker was tripped (open circuit, short circuit and earth fault) after attending the faults test for its continuity and take insulation resistance of the feeder by using megger. And take the feeder into circuit.
