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 ...

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?

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 Smiley

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





  To tell you the truth im not doing it exactly to code lol !! Im actually just using industrial grade 120 volt outlets that the power supplies can directly plug into with out having to chop the cords and put a huge 240 volt plug on it !! Each power supply dont pull that much current, not nothing like a dryer would so you can get away with it. So basically the 120 volt outlets will just be supplied with 240 volts instead of 120. Just make sure you make it clear that its 240 volt plugs dont plug in a 120 volt fan or anything on accident lol ...  I also highly recommend the fuse box or atleast some inline fuses that will give you added protection. Remember that 50 or 60 amp breaker you install won't trip untill it goes over the Amp rating.. That could be enough current draw to hurt your power supplies or miners in the case of a short,overload or failure of anyway...
