My residence (2000sqft, 200amp) houses my wife's business. The load include 6 computers and electric heat.
The 8 hour load is less than 34amp @120 volt (about 4KW).
If that load were on only 3 20amp circuits, the circuits would be loaded to only 50%.
I think that loading used in the tests might be a bit high for residences.
