thank god you are still alive. not just for your own sake either. if you had died than the government would have ceased the opportunity to ban bitcoin saying "sorry we had to ban it but its only for your own safety, you have to understand, bitcoin burns people alive".

I think I have read that already somewhere...

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 ...

They do make North-American 240V power connectors that are not much larger than the 120Volt connectors. Not sure what premium the power supply cables with a 240V plug would carry though (If you are an electrician, you would be able to just replace the plug).

Somebody up-thread was talking about 2 30 Amp PDUs on a 50Amp breaker. I suspect it would not be too hard to find a 20Amp breaker for one of the PDUs.

Sounds like you had bad wiring in your house, and once you put a constant 80%+ amp load on the circuit the wiring heated up and eventually caught.

Just because it ran for a week doesn't mean your OK, you need to make sure you don't exceed 70-80% of the circuit amperage.

I've seen many houses in my area catch on fire from electric heaters. Those big ones pull 8A - 15A alone from the socket and easily overloads it.

I very good lesson for all of us. I guess it's only a matter of time before something like this hits the mainstream news as another blight on bitcoin.

I had a 20ft 16 gauge extension cord that melted, but didnt catch on fire or anything.... uh, the socket of the power supply or whatever melted out.

I use 12 gauge 50' extension cords now. these:

except when I bought them they were only $50/ea.

oh, this was just from your typical household socket here in the US (rated for 15 amps)

What temps do you run your antminers (s1) at??
Always wonder, my ones showed ~64C on average however, when touching the heat sink it was like touching the asicminer 333mh usbs :/
Have you had the same experience??
Thanks,
JT

64C

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

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

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...

wow this is certainly something I will be looking into more with my own setup.
I now have alot of reading to do Sad

i 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!

ouch that is scary ... I always turned my rig off when levaing the house for moer than a day just b/c of my paranoia with a fire. I guess there is a danger.

Do you have a pic of your setup before the fire?

I read some reports of the OP trying to scam people before with made up stories, maybe that's why.

wow, i have newer scammed people!!! you can see that in my feedback!!
what posts are you talking about??

I never said you scammed somebody, just reporting back what I read:

This person has been scamming this board for a long time coming up with different stories every time you know what give you away asking for help that is a dead ringer for a scammer. The thing is this when someone wants a dollar they tell them why they need a dollar when a person could use a dollar they hope someone would give them a dollar without asking.

You're probably not the first to have run temps that high but it seems that the general consensus among miners is keeping the device 50C or below. Maybe you should think of adding a duct system behind the miners to pull the heat away from the device and out of the house. Not scientifically researched, just my observation. Also, don't buy cheap miners.
