One thing of note. The current 13.5th s9 bitmain estimates 1323w + 10% which is actually around 1450w. This is about the actual usage as I have tested them on a 94% efficient PSU.


Total power available in watts:

32A * 220 = 7040w

You run breakers at 80% of max for safety:

7040 * .80 = 5632w

Available power divided by per unit draw:

5632 / 1450 = 3.884 units

So 4 would be the max I would put on that circuit.
