Hello, I’m planning on purchasing an Iotawatt in the near future and I’m a little confused about what CTs are required. We have multiple double pole/240v breakers of varying amps 30/50/60. I see the recommended way of connecting 240v is a single CT with both conductors passing through in opposite directions which I understand is due to the opposite phases. My confusion is regarding the sizing of the CTs. If we have a 240v double breaker (not sure if that’s the correct term, it takes up two slots and lever to throw it on/off is connected) that is 60A would a 100A CT be sufficient for passing both wires through in opposite directions or would I be required to get a 200A CT?
What about combining CTs with a 3.5 splitter. I understand they have to be the same model CT and if they are on opposite phases one needs to be turned the opposite direction but again am confused about the total amperage. If I have three 120v 20a breakers, can I use a 50a CT on each one and combine them with spitters into a single input or no because all three at full draw would be 60a?
I suppose the same question then for a 240v 60a, if I use two 100a CTs (one on each leg) and combine them with a splitter would that be ok or no because the total load could actually be 120a?
