Residual Current Detection webinar - How adapting Vigi on 3-poles Compact NSX when distributed neutral?

Hello, 

 

I couldn't understand from webinar what do with molded case breakers, in case of distributed neutral (4 wires) installation.

Should we add a 4 poles Vigi with adaptor on the triple pole Compact NSX?

 

Thanks for giving clarity on this specific case.
