I’m in need of splitting each of our 2 buildings electrical bills between 10 units . Each building has a main panel with a 50amp line that runs off to each of 5 units. The other breakers in the main panel feed communal items (ie. water pump) where costs would be shared evenly between the 10 units. Correct me if I’m wrong, but I don’t think I need to measure every breaker. My thought is to install an IoTaWatt in each building, measure the incoming power and each of the 50amp lines that feed the condo units. If I subtract out all the power that went to each unit I’ll be able to split the remainder between all 10 units as the communal power usage. That being said I need to confirm the correct parts to order.
Lower Building: Has 450amp of breakers, so an IoTaWatt Generic Kit, power supply, 9v reference transformer, 1x 600amp CT for mains?, 5x 50amp CTs for measuring condo usage.
Upper Buidling: Has 420amp of breakers so an IoTaWatt Generic Kit, power supply, 9v reference transformer, 1x 600amp CT for mains?, 5x 50amp + 1x 30amp CTs (Unit E has additional 30 amp breaker).
In case it matters, the main panels can be switched over to generator in case of power outage, it’s very rare, will that mess anything up?
I wouldn’t mind any insights or recommendations you may have.
Thank you kindly,
Adam
