Older smaller houses may have a 100A drop, but almost anything newer than the 90s would have 200A service. Also, everyone has 240v service. Real easy to tell, go check your main breaker.

Most of the US households are not 240V and 200 Amps though.

Really?  I thought that was pretty standard.

Depends on the size of the house and how recently it was built--unless custom of course. My recent house had 240 (or 250, cant remember) amp service. 2,800sq/ft with a bajillion gallon pool.

Most houses I've run across are 150-200, built within the last 20ish years.

Regarding heat, I can't imagine Jupiters warming up a room too much unless there was no airflow and it was small, they're fairly efficient. If you want warm, I've got a 40 amps  of scrypt miners heating my house right now lol. With more on the way.

[jjiimm_64]

speaking of scrypt miners... and 24k.  I have had over 20k in my shed 24/7 for 2.5 years..  22k most of the time... lots of bug crunching and cigar smoke... they just keep going..

buy good PSU's and keep the clocks down...  41Mh ltc right now.

house is 200amp, as most are .. even many of the old 100 ampers are being upgraded.

W.r.t. Heat I had to share a hotel room with one of the nov boxes on to check it survived the flight. Fell asleep and woke up covered in sweat. I can't imagine what Cyphers house is like right now.

I also spent a night fixing dead boxes in the DC for the hosting on an occasion. October kit only, was a month or two back. In any case aside the monotonous hum. I had to take a break and grab water every hour. Even with aircon in the building it was hot hot hot.

24Kw in summer will just compound the heat...

EDIT: just saw what Bogary wrote as I posted. Most of the US households are not 240V and 200 Amps though.

200A is definitely not typical, that's a lot of power for a home!

I have to disagree.  100 amp service was typical of post-WWII homes of a smaller nature.  I'm pretty sure that split levels built in the late 1950's onward were 200 amp service with two phases between which one would see 230VAC for the oven and clothes dryer.  100 amp service is still put in things like mobile homes but mobile homes aren't houses.  What goes into a small ranch now-a-days is probably 200 amp since electric stoves and clothes dryers are the norm.

[RickJamesBTC]

They are not two phases. I wish people would stop saying that. It is 240 V single phase. The voltage is measured across the peaks. I have three phase power at my shop, which makes for really cool diagrams and difficult explanations.

The rest is what I said earlier though.

not quite 3/4  .. wired most of the psu's to 220, so that lowers the amps.

Yeah, I'll be doing much better on power costs with a switch to large 240v server power supplies.

I dont think you have to switch.. MOST psu's on the market will take 220 ...  I actually just wired regular 20amp plugs with 220 and plug my psus right in...just dont plug a light or a fan in that plug!!

Thank you, I know that. I've been running PC power supplies for a while now. I meant switch to server supplies, I've got 12 of them now at 2000 w each, vs who knows how many expensive pc psus.

You really shouldn't wire a house like that, liability issues and all that. Use an industrial plug, wire it to standard splitters.

[jjiimm_64]

back to KNC... is KNC going to offer in stock sales?  do they have any current models coming for sale soon?

EDIT: just saw what Bogart wrote as I posted. Most of the US households are not 240V and 200 Amps though.

Depends. That is actually the standard for single family dwellings and duplexes, since 1973. However, a lot of apartments now run 150 amp. 240v in is standard, to make it possible to run a dryer and a stove. A lot of mobile homes have a 100 amp service, and a few older aparments. The one I'm in is ten years old and an "economy" unit. (read low income housing). It's main is 125 amps/240v. That's kind of weird, actually, but I've seen it before. 150 is much more common in apartments built in the last thirty years, 100 before that. Most houses, unless really old or in the People's Republic of Pennsylvania, are 200amp/240v.

I should also note that upgrading a single family dwelling to a 300 amp service is easy and relatively cheap. By comparison to the price of your mining machines, it's damn near free. All told, if you do the work yourself, probably less than 500 dollars including inspection fees and the upgraded meter fee. Adding circuits can be difficult if you want to keep them concealed in walls, but if you were powering a shed or something like that, just run a line in a 24" to 36" trench to the shed and leave the inside wiring exposed. There's no added danger from this, and if you have neat hands it looks cool. It's also easy to just run a second line of service to an outbuilding.

The theory behind electrical load calculations and such is complicated and scary if you aren't an electrician or a mathematician. The actual mechanics of it are simple as hell.

Where can I sign up for new newsletters?

I got the original upgrade modules email, never got Neptune even for existing customers,  never got this supposed new one.

Still furious about their disregard for pre existing customers. And now I can't even get damn updates.

Could the question of Jupiter sales if and when have anything to do with some customer trying to buy up as many as possible?  We see photos of major hashing facilities where were they, in Hong Kong and Iceland?  Those big facilities can operate on a thin margin and make a good profit while that same rate of return for small miners would be a big disappointment. But how would that lack of information limit sales to a buyer with the money, it wouldn't.

For the last time the piece on a facility in Iceland was Cloud Hashing. They had a big order in the beginning and have not been sold anything more than what was in that initial order.

So Cloud Hashing hasn't ordered any Neptune's?  Any other similar operations ordering a giant amount of Neptune's going forward?

I can't say they have 0 orders for Neptunes but they jumped in heavy with Cointerra this time, building a new Data Center right by Cointerr'a TX facilities. If anyone has the luxury of making the decision today Cointerra would probably be the best bet at the moment, 2TH/s in January is a solid play.

yeah my assumption if cointerra does start shipping jan 15th in a reasonable mass amount ..then I think knc will release more jupiters in the wild aggressively priced (by that I mean less then bfl's monarch supposedly feb at 2.5k...kill bfl please 1.5k Jupiter would do that)

anyway....

if cointerra just trickles stuff out in dribs etc etc ..and not much is seen before Feb of any competitor ..I myself doubt knc will release any jupiters in the wild if they have an aggressive get the neptunes out by april 1st plan

but then again if they do ship them last gasp of jupiters ..;price them dirt cheap ....break even only....bury some of these scam asic sompanies like bfl and such......that's would I'd do....to protect the knc market share...bury em.....imho.....

(of course they ..knc that is...seem nicer then most of us here..imho unlikely..they will do that ....but hey a guy can dream)

So we small miners might be mining bitcoins looking like toy sales in the small neighborhood candy store while a Toy-R-Us and a Walmart are under construction on the same block.

This is what myself and a handful of others have been saying for quite awhile now. Are you just now seeing the writing on the wall?

There is a limit to the amount of hardware households can sustain. Neptune in theory is currently the ceiling until another full step down in process node to sub 14nm, as it's power consumption may limit one device per household mains. Then of course you have the amount of hashing power to remain competitive to contend with. It inevitably will have to be housed in a datacentre.

that's my question in usa you have 30amp circuits 220v for stoves and clothes dryers etc

you also have 220 volt circuits which are essentially 2 20 amp circuits (wire) on a 20 amp breaker

so which kind of 220v we talking about here ...30amp wire or 20amp wire?

I have a 100amp service...(no central air or furnace or heat ...just boiler heat only ie small pump)

so I could easy put in 3 220v 20amp breaker circuits in for 2 Neptunes and 1 220v for a kick as window air unit to cool them....

if you are talking 220v 30 amp the kind of stuff you use for stove or clothes dryer that could be a streach (although who needs as stove or clean clothes?)

anyway others who have looked into this from the USA end...which of these is the more likely scenario?

If it was me, I'd upgrade the service. Your meter is almost certainly a 200 amp, as most of them are, and a 200 amp main service is cheap. Wire in the new breakers exactly the same as the old ones, and you're set.

And yes, 220/240v nominal for dryers and stoves and such is the same. Different plugs, sometimes, but that's a simple receptacle. Just get the one you need for your device. All of this is available at Lowes, Home depot and such. At a minimum, I'd go up to 150 just for the larger panel space. The wiring is simple, and there are a number of good books on the subject that take a complete newbie through the basics of house wiring. Depending on your jurisdiction, you'll need to get it inspected once the panel change is finished. For any 20 amp circuits, I'd say a minimum of 12ga wire, bigger is better for safety, but not cost. Overkill on capacity is not a bad thing when you're running a high draw device.

Does anyone notice that their miners generally runs better until the first flushwork?

I get around 1% HW errors, and after a flushwork occurs, it shoots up to 3-4%. The HW ticker goes from 1-7 a jump to upwards of 50 a jump.
