Connecting the neutral wire when installing the difavtomatov
Good afternoon! In the house there is an introductory three-pole machine 25A, in addition to conventional machines, I want to put diffs on wet outlet groups, in phases. Is it necessary to separate zeros with separate buses or can all zeros be on one bus? Thank.

Hello! After the difavtomat, all zero wires must go separately to the loads along with the phases. But before the differential automaton, zeros are connected to the common zero bus.
Good day! You do not write what is your single-phase network?
two or three wired. And is it important!
Of course, after a single-phase (bipolar) DIF, zero and phase go from it from the bottom, and if there is no protective zero, then its effectiveness (DIF) decreases. But in practice it is verified that it also works on leakage.
