Multiple phase L1,L2,L3

[tombueng]

Hi,

do the L1,L2 Input need to correlate to the current measured?

I.e., when attaching L1 to Block 1 and L2 to Block 2,
must i only measure L1 currents on CT #1-10 and L2 on CT #2-20?
Or is the L1,L2 only used for voltage measurement to be able to calculate P=U*I from that?

Or can I mix this? e.g. measaure L1,L2,L3 (e.g. for the oven) with Inputs #1,#2 and #3?

L1, L2 ,L3 only use for detect AC VOLTAGE, not use for "current".
if you use single phase, only use any L with N for monitor VOLTAGE. if you use 3 phase. you can connect L1,L2,L3 and N.
monitor "current" use by CT sensor , connect to CT sensor INPUT ports.

Hello,

I got the N20, which only has L1 and L2, but my home is 3 phase. Do I need to switch this board for one that has L3 as well?

sorry, N20 not support 3 phase power line. N30, N60 support 3 phase. N10, N20 only use for 1-phase.
