Hi. My panel has 4 mains going into 4 breakers connected as one. Would I install 4 main CTs for this setup? Would each CT go into an input on the iotawatt or would I join them (with a 3.5mm merge) before feeding as an input into the iotawatt?
Similar question for the bottom breaker (with the red wires) which has two breakers joined together (60A total).
