I was reading this article, amps per leg on 220V? , and it was very helpful in understanding how to measure a 220v circuit.
My question, based on the answers given there, is how to measure the amperage of the entire panel. The measuring should be similar to measuring a 220v circuit in that measuring only one leg will give you the 220v flow for the entire house, but that would not be showing the 110v flow. So, to properly measure the current usage of my house, would this "formula" work? Using three clamp meters, measure each leg in the panel then:
--Add both hot legs together.
--Subtract the neutral leg.
--Divide by 2.
--- This would be the 220v current usage.
-- The neutral current would be the 110v current usage.
--- Add the two above together to get total current usage.
- Use those two numbers referenced to their voltage to get the wattage.
That would give the 220v and 110v current usage of the house and, referencing each to the proper voltage, determine the wattage?
