Q1:
I’ve read my meters twice today.
The left meter is for general usage, the readings are 22422/22424;
The right meter is for controlled load 2, the readings are 13000/13003.
I don’t understand today is Sunday why my general meter is still counting. Why not is the controlled load meter counting only?

Q2:
I am going to buy a large appliance but only use it about 10 hours/day, at night. I think using the controlled load 2 meter is the right choice. How can I connect the appliance to this circuit?
