Neutral does not carry curret only in the cae of a balanced
load. However in the case of an unbalanced load ( 3
Phase ), neutarl definitely carries the unbalance current.
That is why we have 4 pole ELCBs - to ISOLATE THE CIRCUIT
IN CASE of fault in neutral

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
