Im running 8/3 gauge wire to a 8 outlet 240 volt plug in box that my power supplies will connect into. Im also thinking about picking up a 40 amp fused disconnect box like what you would use for a hot tub power setup, that will be installed befor the outlet box. I work as a industrial electrician so my set up might be a little over kill but it will allow me to run at least 5000 watts of mining power... After all the miners are running on the 240 volt supply all you have to do is put a amp meter on the line and find out what you current draw is to figure out the size of fuses to install in the disconnect . The calculation is pretty simple ..Total line Amps x 1.50 = size of fuses to install to protect wire feed incase of overload or power supply failure.You can also do the calculation at 1.25 if you want to be even more on the safe side

I'm interested in your power config here. Are you running multiple lines off the same 50 amp breaker or several lines off several 50 amp breakers? How are you setting that up?

This is exactly why I installed a 50 amp breaker in my panel and im running the wires tonight after work. This is pretty much the only way to continue to mine bitcoin at today's levels. 15 amp breakers on your normal outlets is a huge fire risk on anything over 2000 watts. It's not only the miners that is the problem its overloading the wires in your wall wich can catch the whole house on fire... Also you can run your power supplies at 240 volts wich is more efficient and will produce less heat ...

wow this is certainly something I will be looking into more with my own setup.I now have alot of reading to doi wanted to go to bed.. its 3am..i've got 6 290's burning, well I should not say burning anymore. Mining perhaps is a better word for them.no fires yet!

Oh ok, cool. So you're running a single line of 8/3 gauge wire to an 8-outlet 240v plug. From there, are you plugging your power supplies directly into the 8-outlet plug or do you use power strips or a UPS in between? Can you even use power strips or UPS's on a 240v line? Shows what I know about wiring..lol
