I just received a 3 pack of the aeon home energy meters to start monitoring some individual circuits (e.g. furnace blower, central AC, … dishwasher maybe?), and am a little confused where to put the clamps.
I saw there was a thread about using each clamp to measure separate circuits, so 2 clamps could measure 2 different circuits. I put one clamp over the hot going to the 20a breaker for the furnace, and was going to put the other one on the AC, but it looks like that one is a double 40a breaker.
Do I squeeze one clamp around both wires going to the double 40a breaker? Or do I need to use 2 clamps for that?
