Title: Power setup for Antminer S9 Post by: KEBKR on July 07, 2018, 02:49:28 AM Hi. First of all sorry if this has been covered but I couldn’t find an answer specific to my setup. I have a fuse Panel, that’s old fashion glass fuses not breakers. I have a 12-2 wire to a 220v (red wire to one side and black to the other ) with 2x20 amp fuses. This is then connected to a dual 20 amp outlet. Does anyone know how many s9i units I can connect to this setup. Could I do 2 per plug so 4 on this one line? 2 on the top outlet and 2 on the bottom?

So if the circuits are 20A then no more than 16A continuous each. So 2 Antminers per. Are you saying each outlet has a separate wire run? Or are you saying 2 outlets using one run of 12-2 wire? If it's the latter then you're limited to 2 miners period. If it's one run of 12-2 wire to each outlet then 2 per or 4 total if you have 2 circuits.

My whole datacenter is wired based on (2) miners per 20amp 220V circuit.

Yes one 12-2 wire run from the panel to a dual outlet. So I’m limited to 2 miners per lead. Thanks for the response, much appreciated!

Thanks for the response, much appreciated! Hold up, you're using 220v so both wires carry current. If you physically only have one piece of wire that is 2 conductor 12 gauge then you need to change the outlet to a single as you have a SINGLE 220v 20A circuit. Previously you had 2 110v 20A outlets Title: Re: Power setup for Antminer S9 Post by: KEBKR on July 08, 2018, 02:24:41 AM Hold up, you're using 220v so both wires carry current.

This is connected to a dual 20 amp outlet. Title: Re: Power setup for Antminer S9 Post by: tim-bc on July 08, 2018, 02:32:21 AM Agreed. My whole datacenter is wired based on (2) miners per 20amp 220V circuit. I second this, the miners that I work with are also wired with 2 S9s per 20A breaker. Title: Re: Power setup for Antminer S9 Post by: Raymond_B on July 08, 2018, 02:45:57 AM Yes I have one 12-2 wire with the black wire connected to one 110v leg and a 20 amp fuse and then the red wire connected to the other 110v leg and another 20 amp fuse. This is connected to a dual 20 amp outlet. I just want to make sure you understand that you will need to replace that outlet with a single outlet, you do not have 2x 220v outlets. You've got 1 220v or 2 110v Title: Re: Power setup for Antminer S9 Post by: KEBKR on July 08, 2018, 02:53:59 AM I just want to make sure you understand that you will need to replace that outlet with a single outlet, you do not have 2x 220v outlets. You've got 1 220v or 2 110v I’ve got this receptacle but what’s the difference in using this as opposed to a single outlet with a power bar with 2 miners attached? https://www.homedepot.ca/en/home/p.20-amp-duplex-receptacle-ivory.1000135014.html Title: Re: Power setup for Antminer S9 Post by: Raymond_B on July 08, 2018, 03:15:38 AM Nothing :) You're good, I thought you might have been thinking you actually had 4 circuits and were going to try to run 4 miners!
But you got it! Title: Re: Power setup for Antminer S9 Post by: KEBKR on July 08, 2018, 03:47:09 AM Nothing :) You're good, I thought you might have been thinking you actually had 4 circuits and were going to try to run 4 miners! But you got it! Ok thanks. Appreciate the help! |
