Since our single phase power use max 13 socket/ plug for S9 ASIC.Power consumption for each ASIC is approx 1200W or about 5Amp of current.So each socket/plug can accomodate 2 ASICs.For single phase for home use is max 100 Amp.So max 20 S9 ASIC can be connected ( not recommended ).

You mean with single phase in home can only have 10KW.That means only 10 max S9 ASIC can be connected.I did 2 years ago connected 8 S9 ASIC without any problem.Only heat and noise was the problem
