Thanks for the input guys. Pretty much scratching that idea.
This place is going for $3,000 a month and has 800 amps at 208/120v, could possibly negotiate down. Electricity on average would be about $.025-$.029 a killowat. Anyone think there's a small business/mining opportunity here? Anyone think the community would be interested in pitching in for some kind of a "group host"/"group buy" option? Been thinking. Or 800 amps too little since that gives ~290kW. Another option would be to spend $30-80k alone upgrading to 3000 amps (1 MW), but that would be a much bigger project of course, and more capital.
Where are you located? Are you sure you power isn't coming in at 480V? |

I'm in the US. Circle I've found has sell limits so unless I can get those raised that's not an option.
I was looking at LakeBTC. It seems to consistently have a higher price than coinbase (and most other exchanges) and you can transfer money in and out via ripple with no fees.
Any other exchanges allow fee free transfer via ripple?

Does anyone know where the Excalibar is manufactured? I need to know for a customs form.

I receive payment from most of my customers in BTC and was wondering what wallet/exchange on average gets you the most bang for your buck when selling BTC.
It looks like circle is usually a better choice than coinbase, (by about 1%, and bank withdraws are faster) but was wondering if there was a particular exchange that I should be looking at where the BTC price is usually high and withdraw fees are low.
Even if I can get 1% it could mean $10k or more a year for my business.

Are you going to allow visitors to your site? I live about 70 miles from your site. In fact I'll be in wenatchee tomorrow....and every weekend the Wild have home games (season ticket holder).
I'm not really concerned about security. We just installed CCTVs today. Our building is made of concrete, no windows, with doors with heavy bolts. We also have door alarms and motion sensors. Are you willing to sign an NDA? Robert |

Each of the 3 distribution panels (208/120 breaker panels) would have a 225 amp main breaker, not one single 225A breaker on the 208V output of the transformer.
Transformers are sized to permit 100% of their rating therefore 278 Amps (100080 watts) of 208V is avaliable for the 3 distruibution panels to share depending on connected load at each panel. In theroy it would be possible to load up the distribution panels (even following the 80% rule) to exceed the 278A output of the transformer but doing so would cause the main transformer breaker to trip on overload.
Best to have a qualified electrician or electrical eng review your plans.
Trends
Always a good idea to get a review by an expert. Some transformers can be overloaded depending on their insulation class and ambient temperature. |

You could include hosting as a subsection, that needs its own topic as well.
Who's with me?

i'd love to come up and see it , come down to OR see mine , compare notes , see some synergies  Haha, how big's your mine? and how much you paying for power? |
|
|
|
This looks amazing.
Haha, wait until the 20th of Jan when we put in LEDs and Blacklights =). |

this whole thread looks sketch
Care to elaborate? |

okay its out is this 225amp max at a 208volt's max this is because of 225 Amp Main Breaker this puts it at 46.8 kw's here is a calc for it http://www.rapidtables.com/calc/electric/power-calculator.htmput in the volts output of 208 and amps max is the main breaker of 225amps hope this helps edit its not 3 phase as no power factor is listed in spec First of all you can tell there's a 480/277 to 208/120 transformer in here because those are the voltages listed in the listing, which clearly indicates three phase power because 208 is the line to line voltage between two of the phases and 120 is the line to neutral voltage between a phase and the neutral. Also you multiplied the output line to line voltage by the input current, incorrectly. After the current passes through the transformer it will will increase (as indicated in the listing) because a transformer will change the voltage, and the current, but the power remains the same. P = (V1 x I1) = (V2 x I2). Still don't understand how this will "supply" any "watts to [12V] mining equipment [OP]" though... That's the job of the power supplies. |

Can you clarify the power costs a bi? I'm assuming you're not charging for KWh. So let's say you have a miner that uses 1Kw and you run it 24 hours a day, is that $95?
Thx
Yes, that's how it works. That miner would cost $95 a month in fees, which covers electricity, cooling, networking, maintenance, etc. |

 Here are the transformers outside our building. 4 MWs of transformers. They transform the power from 13.2 kV to 480V. |

The last thing we have scheduled is inspection on the 29th of December.
So how did it go today? The inspection date got bumped up a few days. |

KVA is equivelent to KW?
I thought there was a conversion involved.....
Nope, generally when you use KVA you're talking about the rating of equipment, while when you use KW you're talking about actual power usage. Make sure to load each phase evenly otherwise you'll cause harmonics. BTC address: 1KDDR9VrkjXugxrsnT4BjDWbNbyYDwSCC1 OK, you win. Coming your way. Got it, thanks! Feel free to PM me if you have any more questions. If you're trying to mine, I may be able to give you some pointers that can save you lots of money. Check out the mine we're building, link in my signature. |

120 volts at 278 amps is 33360 watts
That's another way to look at it, but you forgot it's 3 phase so 120*278*3 = 100080 watts = 100 kw |
