Nice.
Thus kWh.kWh
Note that Amps is not "power consumption"... for power consumption you NEED amps, but you also need voltage and a way to determine power factor. Then "power" is drawn, but is not the same and "energy" that is consumed. For energy consumption you need to be able to integrate power drawn across time, or what's called a kWh meter. That's what the devices mentioned above actually are, I'm just pointing out that the original request for CTs and an ammeter would NOT provide power draw or energy consumption.
