I'm wiring my house with 6 x 30-amp 240v circuits to handle my mining equipment. I'm more worried about cooling to be honest  Yes, I think the low end, efficient, window AC by Haier got bumped by $30-$50 after the summer. Went looking the other day. 30 amps at 240v is 7kW. Six of them would be 43kW. That's 40 btu per second - or 146,722 btu per hour. A 'low end' window AC isn't going to do much. You just need a lot of ventilation - replace hot air with air from outside, as long as it's less then 70C outside you'll be fine. well, I hope the Neptunes are 220 for your sake.... lol bold...doing that without knowing... Yeah, I've got 14 x 220GH/s miners that eat 1kw each arriving soon. They come with 220v power supplies that would probably work on 120v outlets, but I don't want to risk it. I'm expecting them to heat my house (I'm in Michigan) until spring, but I'll probably have to get some ventilation as soon as it starts getting above freezing. Unless you have a 6,000sq ft house I would expect that you're going to need some HVAC/open windows immediately upon receiving those. The most I can handle is about 8,000 watts in my house in the winter without it getting crazy hot (my house is 3200sq ft). I have a seperate building where my datacenter is to house excess machines that has plenty of cooling, but during the winter I don't keep more than 8kw of machinery in the house. Come end of Feb/March, I move everything into the climate controlled center. |

You obviously don't have a firm grip on household electricity yet. |

It'll need to exchange at a specific rate as well, at least as fast as it heats up. Agreed. Also, Antminers ship immediately, are the same price as the 220GH/s Avalon units, and use ~3 times less power per GH.
Where are you getting your power specs to see that they're 3x more efficient than a Neptune? or did I mis-read you. |

I frequently worked under a licenced Electrical contractor, and he will sign anything i do Just sayin 110 combined to 220, then to the psu... then back down to dc... more conversion = more waste. He will be able to run more neptunes, because he installed more circuits... weather you have 100 amp or 200 amp service will determine the amount you can run, period. Europeans are lucky in that area |

Europeans are lucky in that area No offense, but you have no clue what you are talking about. Yes, two 120 pulls are combined for 240v in America. I am in America. I said if you have a proper PSU, anything will work on 220-240V, and my statement stands. You obviously have no clue what you are talking about. I feel bad for whomever let you work on their house. I constantly take switching ballasts and PSUs from a 110v socket to a 240v scoket with zero issues. I do it with Jupiters. 4 GPU rigs. 1000w ballasts. You name it. A little warning to others: don't take electrical advice from that guy, apparently the internet has made us all professional electricians! |

Europeans are lucky in that area Um. No? 220 is more efficient.. period. "As for efficiency, 220V takes the cake. P=V*I and Ploss=I^2*R. For a particular appliance (say a computer) that uses a fixed amount of power the 120V country will use approx. 2X the current from the 220V country - for the same total power. What changes is the power lost - the power lost through the wire is proportional to current only, not voltage. Therefore the higher the voltage the more efficient the transmission is. Instead of taking the extra efficiency, 220V circuits tend to use smaller wire (thus saving copper/raw material instead)." |

IIRC in the US it goes from 3 phase to a transformer which breaks it out to 3 or 5 poles, heck I forget. Anyhow from there you get your 240 which is split to 220/110 or whatnot.
edit, looks like someone beat me to it.

if you think you have actual 220 running into your home... guess what... lol you actually have two 110 lines which are combined to make the 220. The psu's mostly can handle either, yes, and 220 is more efficient in general... but what most don't realize is that your amp rating install is the limit. You get 100 or 200 amp service usually...just because you install 220v circuits, means nothing towards running more neptunes. But ok...I don't know what I'm talking about.... lol.. believe what you want. I have too many installs under my belt to buy that load of crap.
200 amp service with 220 means you have two lines of 110 @ 100amp each. that's it. Running a psu at 220v doesn't change the amount of power ran to your home. lol

We have actual, 3 phase 240v service from our main panel here. ~1400A total capacity @ that voltage |

You obviously don't have a firm grip on household electricity yet. If the Neptunes are 220-240vac, he's okay. If they run at 115vac they'll draw twice the current each. If he has power into a room that via 12-3, it can be broken down into 115vac outlets some with L1 as hot and some as L2 as hot but the return on the 12-3 has a single neutral. If Neptunes are to be run at 115vac (unlikely but possible) he could put 2 in series in a McGiver sort of arrangement. That would keep the current down. Oh and one would not plan to run 12-3 or 10-3 to be split into 115vac outlets. And sorry Phoenix, I think two 115vac do not add up to 230vac. Although only 2 phases come into a home they are generated in 3 phases I think. They do not add up as 1 + 1 = 2. |

Just sayin
on another note... Good thing no miners here ATM... My new 200 amp service line took a direct lightning strike last night  It blew every breaker in the house, both live phases It exploded a 20 amp power strip, blew my desktop, microwave, and left a 3 inch long exploded hole in the new conduit. It struck on the portion of the line we had not been able to bury yet. The mains are literally in pieces. After calling the power company, they come and find that my transformer is also blown. They patched me into a local transformer down the street a bit, but only one phase is still working with a huge exposed/blackened hole in the conduit for now until I can fix this mess. oh boy. So far I was able to get a set of dual 100amp switches for the mains and a microwave oven (Gotta warm that coffee) to get going Installing all new 2-2-2 in conduit is gonna be fun I have no way of splicing the hit portion of the service line do I? |

Talk to your power company and they can probably pull 3 phase to your house (if you have commercial area for it on your property, there is no reason to have 3 phase at a house unless your draw is at least 20,000 KWH per month in my opinion--at which point you aren't really "living in the house"). I live off a state route in the middle of nowhere and my power company was able to get me 3 phase (at this point, you can pretty much get as many amps as you want at the location). |

Just sayin
on another note... Good thing no miners here ATM... My new 200 amp service line took a direct lightning strike last night It blew every breaker in the house, both live phases It exploded a 20 amp power strip, blew my desktop, microwave, and left a 3 inch long exploded hole in the new conduit. It struck on the portion of the line we had not been able to bury yet. The mains are literally in pieces. After calling the power company, they come and find that my transformer is also blown. They patched me into a local transformer down the street a bit, but only one phase is still working with a huge exposed/blackened hole in the conduit for now until I can fix this mess. oh boy. So far I was able to get a set of dual 100amp switches for the mains and a microwave oven (Gotta warm that coffee) to get going Installing all new 2-2-2 in conduit is gonna be fun I have no way of splicing the hit portion of the service line do I? Pretty sure I don't need to say anymore...don't trust just anybody for electrical advice, especially on the internet. In fact, if you THINK you aren't SURE about something electrical, hire a contractor. Your wife will thank you when the insurance actually covers the fire rather than them blaming your own shoddy handiwork. Guess you brow beat your customers into paying lots and lots of money. Shoddy? What give any indication the work was shoddy? Lightening will fry anything. Yeah... guess the electric company was wrong saying my install was okay huh... lol shoddy hahaha okay...I'm done rip me apart. lol fact is I don't care really, you can find your own way...call a contractor....his wire is better because it costs more, right? lol That lightning got dozens of homes around here |
