Hi,

I'm looking at getting RFXPwr, but being Dutch, I'm trying to cut corners.

From the documentation it sounds like a I need a separate module for each phase (I'm using 2 out of 3 available phases, each powering 4 groups). But I was wondering what happens if I clamp a single RFXPwr around the return feed (neutral), since it is shared between the 3 live phases.

Any thoughts/experiences?

Thanks!

You need 2 RFXPwr for 2 phases.
The reason is that the angle of the phases is shifted and the power adaptor and the CT must therefore be connected to the same phase.
