What are the blue and red lines used for?

[Marco]

Just received my Vue2 and getting familiar with it.

Can anybody tell me what the function is of the blue and the red line?

Thanks,
Marco

May want to refer to the install guide – this is covered on the 2nd page…

But red is the 2nd hot line (for US 120/240V installs), and blue is used for 3 phase monitoring.

Yeah, I went through the manual, just wasn’t clear.

So should they be on different phases? Because in the manual they seem to be on the same phase.

If they are supposed to be on the same phase, why 2 on their own different breakers on the same phase? Just trying to understand the logic 🙂

The manual is very detailed and covers multiple install scenarios based on how full your electrical panel is.  If this is a US installation (split phase 120/240V), the best accuracy is achieved by using a 240V dual breaker and connecting the red and black wires to each respective phase.  Blue and White then go to neutral.
