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.

I would say listen to your electrician.  Every country has different electrical codes.  And just because you "Can", do something theoretically, doesn't mean you can do it in your country.  I am pretty positive the electrician won't say, well if you heard it on the internet, then I will wire it that way. 

omg almost 10KW continuously  running in the garage - sounds scary.

yes, listen to the guy. Try to not use single and big/strong/powerful breaker. Try to use many breakers - one for each or two devices.

Exactly! Listen to the electrician and at the very least get a second opinion from another electrician.  Don't trust us on the internet with this one buddy

Yup listen to experienced man in his field :).
You got good advices already, i see u also get serious to this mining topic.

All i can do really here is to wish u best of luck, u will need it, i mean its very competetive area of business.
Keep in mind difficulty will rise constantly.

Consult an electrician that does commercial work if you can.  That's not typical residential stuff.

Also, depending where you live you might get attention from certain organisations guessing that you run a cannabis farm judging from your power consumption. Heard about such visits in the US.
