Does Gen 2 PSU phase need to match sensors?

I ordered a Gen 2 and haven’t received it yet so this may be a dumb question but do the power supply wires to the Vue need to match the main sensor phases?   In other words is one of the 200A sensors considered “Red” and so must be on the same phase that supplies power to the red power cable from the vue?

I asked support this question yesterday during a 3-phase install and they said the order for the red black blue wires doesn’t matter relative to the A B C CT’s. Black is power and red/blue are voltage measurements.

Thank you @mjmott.   That’s good to know.  I guess you wrote one answer for each phase?  🙂

Now that I’ve installed it I see that the Main channel only reports total energy consumption so it makes sense that the assignment to A/B/C doesn’t matter.  This also answers a related question, does it matter if the main sensors get unplugged then plugged back in backwards or to different main sockets?  I know now it doesn’t matter.

That also explains why blue needs to be tied to neutral when not used.     It prevents measuring noise or anything else.  I was wondering that… thank you.
