I read several times that people had to re-wire their fusebox, because otherwise the PV input vs main consumption cannot be measured in a correct way. Now I want to ask a stupid question maybe (I don't know anything about electricity... ;-)). If you have multiple wires coming out of your ELCB, can you put those in 1 clamp? Since I want to read the consumptoin coming through all of these wires (they go to individual fuse boxes), logically this should be OK. But I'm just wondering if this physically would work...
Tx,

If the wires are on the same phase (i.e. fixed to the same screw of the ELCB), you can.
