Is it okay to consider only phase to phase faults for the end of line fault as it produces the minimum fault. Is there any probability of phase to earth or 3 phase faults getting lower than phase to phase faults.
I tend to think that if the breaker is of current limiting type / fuses, the maximum length of the cable need not be verified. Cable size based on let-through energy is not dependent on the length of the cable. Indeed as the fault location is further away from the breaker, the let-through energy decreases which improves the situation.
