I have 3 separate 220V double pole circuit breakers that I would like to each connect to a kwH meter, so that I can track the energy usage that goes out from each circuit breaker. These double pole circuit breakers have a black and red wire going to the load.
One circuit breaker feeds another circuit breaker panel for all of my baseboard heaters that total a combined maximum load of 72A. The second circuit breaker goes to my dryer which is rated at a maximum load of 25A and the third circuit breaker goes to my hot tub which is rated at a maximum load of 18A.

Thanks for your suggestions. I actually was looking at these items previously. However, I am not sure how I would connect them to my 220V double pole breakers. Do they really work for a 1 phase 3 wire breaker? Again, I have 2 hot wires, black and red, coming out of the double pole breaker going to the load. According to the diagram on the back of your kwH meter, it shows 2 wires that are connecting from 2 of the terminals of the kwh meter to 2 wires between the AC Input and the load. Are these 2 wires the 2 hot wires, black and red, or are they meant for a 2 wire system, such as a black and white (hot/neutral)? Also over which one of the wires does the CT have to go over?
