I only want a neutral as we are installing RCBOs on the load side. The neutral would really only be for the Test button and completeness and to match the other sets which arent the same but have a neutral.
I have the PDF at work which has a schematic of it. Could one of the mods put the file on the ecn server so we can have a link? The only loads are 3 phase.

I took my time, I hurried up, The choice was mine, I didn't think enough
