In my jurisdiction 2.5k is probably what you'd need to slip under the table to the inspector to get him to show up on the same day. It was much easier for me to lease a small warehouse that happened to be pre-wired with 600 Amp service.

Longpool/work restart signal (that's what causing flushwork to be done) rate is varying from 30s on p2pool to couple of minutes on other pools. Miners are designed to work 24/7 without restarting. You looked at stats from minute or two, which means absolutely nothing and can't tell overall device performance.

well my jurisdiction....the util company will cut off power but will not turn on power again unless all panel work is done by licensed electrican and inspected also before power is resumed..so you have to have the electrician do it..and the inspector there later in the day..or you get no power back..also to go from 100amp to 200amp it is 2.5k for both the util to do this the inspector and the electrican to swap the panel etc ..this is in Minnesota...so no easy out for me (also in town may have had better luck if just dealing out in the county)

so sucks

oh and this does not count if the util has to run a bigger feed 100' from the util pole to the house (ie replace that wire) that is extra and my cost as well

so screwed

but again 100amp new panel etc....no house wide a/c or house wide forced air furnace..so I likely COULD  run 2 Neptunes and a 220w a/c unit upstairs in the window ...if they are all standard 220v 20 amp circuits...BUT if they are 220amp 30 amp needed like for stove  and dryer I'm screwed....the lack of forced air furnace and  with house wide a/c  (gas boiler with small pump for heat) I should probably be ok with what I have ..but a 100amp house with a standard forced air furnace and a/c ...........well that would be a stretch

anyway these prices are from 2yrs ago when I just had a panel replaced from 12 circuit to 28circuit (that cost me 500 bucks just to swap the panel same deal as above)

anyway just for those in usa with minimal use 100amp like myself.....that is how I figure it so far .if I did have to get a new service beyond 100amp would probably go whole hog and get like 300amp or some such rather then simply 200amp (of course that could be also way out even more in price don't know) but just saying

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.

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.

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?

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)

I signed up for the F5 updates on their website

What disregard now?? Geez.

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.

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.

its out in the barn... where all the air is.

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

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.

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!!

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

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

3/4 of your entire primary breaker goes to scrypt mining? Stout! haha

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.

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.
