I am trying to understand if installing 100 Amps CT on 200 A service panel in my house would be me appropriate. I assume it is more accurate on lower loads than 200 Amps CT (I am not sure if this is true though yet).
Here are my rough estimates based on some more assumptions.
Fact: The highest monthly average power is 4 kW.
Assumptions (I do not have any real data - need a PM for that
load unbalance = 50%
load factor = 50%
This yields the maximum expected current as:
4000 W / 240 V / 50 % / 50 % = 70 A
Diameter of wires on the main is 15 mm, which fits the SPLIT-100 CT spec (15.7 mm).
I guess there will be some spikes in the load. Thus here is the question: what happens to a SPLIT-100 CT if current exceed the nominal value?
Are my assumptions valid?
