Hi,
We have always assumed that on an offline SMPS mains input PCB connector, it is best to have the conductors in the order “Live, Neutral, Earth”…..and not “Live, Earth , Neutral”.
The reason being that the “Live, Neutral, Earth” connection theoretically gives a narrower Live_Neutral current loop and so reduces radiated emissions, even if only by a small amount.
Would you agree?
