Hey all, I have a question.. I am about to get started on bitcoin mining, and have a question...
I am looking into getting 4 antminer s9, I understand that it takes a lot of electricity to run one, let alone 4. I had a electrician come out to my house to see how much it would cost to install either a 120v or 240v outlet in my garage. I have 5 spots open on my breaker box, and this is the problem I am having..
If I have him install a 240 v (50 amp breaker), I could run a maximum of 9600 watts (continously, but maximize is 12000, they say for continously only do 80 percent to be safe), I could run 4 psu(APW3++, which is 1600 watt each)  to that one breaker and it would be fine. Right?
For him to do that he would have to put 4 outlets to one breaker. Can that be done for a 240v? The guy said that it would be better to install 4 120v 20amp, that if I went with the 240 I would be able to only plug one of my miners in, and that I would need more spots on my breaker box. (240 watt takes up two spots on my breaker box, and I only have 5 left). So I guess what I'm asking is, is it possible to install multiple outlets for a 240 volt on one breaker, run 4 miners,  or would that not work?
I'm obviously not a electrician and some of the stuff I said above could be wrong. Correct me if it is.
I also know 240 watt cuts half of the amp. So with 6800 watts on a 240v is 28amps, which a 50 is plenty enough.


If it is possible, what kind of receptacle would be best to install for the apw3++

This is a very technical question, and I appreciate the help.
