Neutral Distributed / Non Distributed

Explain me the difference between a neutral not distributed and with neutral distributed.


(3 Phase + 1 Neutral) loads -- > Is this termed as distributed neutral?

(1 Phase + 1 Neutral) loads  -- > Is this termed as distributed neutral?

3 Phase, for example motor  --> Non distributed neutral?

2 Phase, for example lighting fixtures -- > Non distributed neutral?,


I would like to apply the relevant equations to find the short circuit at the end of line. That is why this question came up.

  • 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.
