It seems like someone from BA actually contacted Dogie about his ranking of BA on his thread:

I have just peeked into my fuse box and it says that the circuit breaker for the mains sockets is 32A.

You need to know the amperage of the circuit breaker where you connect the SP30 to, or each of the power supplies. Not the main breaker.


Ok so also, I would need to buy separate circuit breakers for each SP30?
Would you have any good recommendation from e-bay maybe?
I appreciate your help. I'm not very electric savvy


myself in USA I simply have 1 220v circuit wired with 12avg wire rated at 20 amps with a 20 amp 220v double pole breaker and of course the 220v plug at the wall...to do so
into an ISOBAR Euro4 version surge protector 4 volt....here off amazon..I have 3 total 220v plugs/circuits and an isobar euro4 on each one...

http://www.amazon.com/Tripp-Lite-EURO-4-International-Protector/dp/B00006HZ4M/ref=sr_1_3?ie=UTF8&qid=1406427314&sr=8-3&keywords=euro+4

it is cheaper then a PDU and works for my needs...

this was easy to do because in my case it is in the bsmt near the panel..so what the heck overkill....1 power supply of the 2 on the sp30 will be plugged
into the above 20amp breaker/20 amp socket/indv 220v euro4 isobar for each 20amp line/breaker (again this model eruo4 at 220v because the sp30 comes
with cords that work for this)

YOU DO need however to purchase the 220v cord from the power outlet to the euro4 isobar..(it has interchangeable cords) the euro4 comes with the
same type of cord as the sp30 miners will come with...not the one that goes from the 220v isobar to the plug in the wall..you need to match (see below)

below is cords that come with the sp30 and the isobar euro4 above (at least the end that does not plug into the sp30 power supply that can be a different type)

http://www.amazon.com/gp/product/B003MG9F78/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

below here is the 3 220v cords from the isobar4 4 surge protector to the plug on the wall...

http://www.amazon.com/gp/product/B0093WFT5C/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

so yeah way over kill but....should work fine 3 circuits using 3 euro4 isobars...1 for each power supply on the sp30 and 1 for the KNC Titan if/when it comes

again overkill but what the heck...as to the tripplite isobars ...well they have saved my butt before so better safe then sorry...
and again cheaper then a PDU

(silly hobby I could have got a bass boat and it probably would have sunk....with my luck anyway..go figure....toys..toys...toys...)

Searing

Thank you for your advice.
It looks like Isobar is a very good solution. I just nee to buy 230v version (United Kingdom) and also relveant UK socket cables.

EDIT: I understand running a new business is difficult and when things dont work out its even tougher. You will always do better by being upfront and communicating promptly. keep up your efforts and communicate more, it would be nice to see you succeed.

We're communicating. We don't want to give inaccurate information. Stabilizing new system and new firmware takes time. Stress testing the systems also takes time.
I repeat my original request, please be patient.

Guy

I sent you e-mail about voltage over a week ago but you have not replied...

Also could you please ellaborate on:

"Please realize these miners are built to be hosted in an industrial environment. Before you plug these in consult an electrician and make sure to get permits/inspection for any work done...
...These are not home miners like bitmain are, they really need to be in a data centre. A cost you must have calculated on your pre-purchase ROI analysis. "

HashFast should have gone with ranking to 0 because they have failed to deliver 95% of equipment and what they delivered was with 6 months delay. Also they are crrently going through bankruptcy court hearings so they literally ceased to exist.

Black Arrow communication ranking shoudl go to zero. They have completely stopped any customer service 2 months ago. They have never answered any phone calls and they have been ignoring any customer's e-mails for last 2 months. They also, every day, on their forum thread they keep cenosring-removing any posts related to seeking any legal action against them.

Talk to a local electrician or talk to a friend of a friend who is one. This is not something you buy on eBay and do yourself. If you have a 16A breaker for all the outlets in your sleeping room you can use 12.8A of it (to stay within the 80% of the rating). If you need more than that, you could plugin the second power supply/cable in another room.

How much current the SP30 will pull will be clear by next week I guess. At 1200W the Murata PSU is rated 8A @ 200V, there are two.

What are the exact dimensions of the unit, please?  D 554 X W 431 X H 88.4 mm?

These seem about right, but you need to add a bit of space for the handles of the PSUs and cabling. About 580mm total length, rest seems right. Add lots of space for air flow, do not obstruct front and back. And expect noise.
 

Look for a 30AMP outlet. You will usually find this in the kitchen around the stove and various enclaves where you plug in toasters and microwaves. This is where you can run an SP30 via heaviest duty extension cord if you don't want it competing with the blender noise or coffee grinder noise:

15-amp Circuit
Total Wattage Capacity: 15 amps x 120 volts = 1,800 watts  
Safe Wattage Capacity: 1,800 watts x 80% = 1,440 watts
Safe Amperage Capacity: 15 amps x 80% = 12 amps

20-amp Circuit

Total Wattage Capacity: 20 amps x 120 volts = 2,400 watts  
Safe Wattage Capacity: 2,400 watts x 80% = 1,920 watts
Safe Amperage Capacity: 20 amps x 80% = 16 amps

30-amp Circuit

Total Wattage Capacity: 30 amps x 120 volts = 3,600 watts
Safe Wattage Capacity: 3,600 watts x 80% = 2,880 watts
Safe Amperage Capacity: 30 amps x 80% = 24 amps

Look for a 30AMP outlet.
That's all good and nice for America with 120V or so, but in the civilized world we use something else Wink
He asked if it would work with "230v 50Hz mains socket".


Thanks for all your replies. Yes that's correct, I have got 230v 50Hz mains socket.
In my circuit breaker box, there are few circuit breakers:
For all house Lights                6A On
Sockets in the kitchen          32A On
Socket for the cooker/oven   32A On
Sockets for bedrooms           32A On
Spare                                32A Off


Does it mean that for my bedroom sockets Total Wattage Capacity is 32 amps x 250 volts = 8,000 watts (50Hz)?

I would need to use bedroom sockets as kitchen sockets are too far away.
There is only my PC (between 500-800 Watt) and 2 table lights plugged in to bedroom sockets. Ocasionally I also use these sockets for kettle, hairdryer or vacuum cleaner.
If above calculation of 8000 Watt is correct I would have spare at least 6000 Watt, if I use all of the above appliances/devices at once.

It says that SP30's nominal power consumption is 2500 Watt So I guess I could have enough amperage to plug in up to 2 SP30s at once?

Assholes deleted my post. It's okay, because most everything is known and archived.

But if you requested a refund from Minersource and did not get it, but they've tried to send you your equipment, drop me a message.


I will keep posting. Keep deleting me. We'll see who gets tired first.
I would like to see someone take legal action against these toddler engineers and management at black arrow. Perhaps that guy who is out 25k? Keep us posted.

Everyone should read blackarrow's trust feedback.

Yeah, they deleted my post too, fools.

I don't know if it would help or hurt, but perhaps opening the lawsuit up to being some type of class action suit. Wouldn't lawyers like this? The more they recoup the more they get? I know a lot of people who have been burned would more likely than not jump on board, if someone is willing to take the case perhaps it could sweeten the pot for them that much more.

Even the merchandise they have shipped seems to be sub par at best and missing things that were supposed to be included when originally ordered i.e lcd screens.

Yeah they deleted my post for the second time. They certainly have time to read the forum.

There is another non moderated thread for BA.

Could you give me the link, please. I'd like to post this important information there so people can share.

@ 220V you will need ONLY 1 (one) 15A circuit ...as SP30 is rated @ 2700W / 220V = 12.3A ONLY... Grin

ZiG

SP30s are a continuous load (they are expected to run for 3 hours or longer at a time at full load), which means that their loads have to be multiplied by 125% before comparing the load to the circuit ampacity.

125% * 2750W / 220V = 15.0 amps. There's a chance you might be able to put that on a 15 amp circuit without tripping any breakers, but you should be planning for the worst, not for the best. Typical circuit breakers will have a moderate to high chance of tripping if they are loaded at a continuous 80% of their rated capacity.

http://advanceelectricaltraining.com/advance-electrical-training/continuous-loads-decoded/

The 125% (or 80%) rule is all over the place in the National Electric Code. It's also how circuit breakers generally work. You can get away with loading circuits higher than that sometimes, but it's basically the electrician equivalent of overclocking. You shouldn't do it unless you have a back-up plan and don't care much about breaking laws and tripping breakers.

Thanks a lot for clearing this out for me :-)

I have just peeked into my fuse box and it says that the circuit breaker for the mains sockets is 32A.

How many SP30s do you think I could plug in before the fuse goes off?? lol

Anyone have a link for what mounting rails/ears? Or specs on what to buy?

Should add meant for Sp30.

The dimension allegedly are: D 554 X W 431 X H 88.4 mm.
I'm personally considering buying this: http://www.ebay.co.uk/itm/291075344625?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649


Does anyone know if there will be any problem with plugging my 2 x SP30 at my apartment, in United Kingdom, to 230v 50Hz mains socket? Someone on the forum once mentioned something about some issue.

I just need the mounting ears for a standard data center 2U rack mount. Not sure what you call them. That seems like a ton of heat for an Apartment. I use air cooling in a Large Garage I pay for and its quite warm with 4000KW. Unless your Apartment is very Large?

I'm basically just curious, seems like a lot of power for an Apartment I guess.

Yes it is a lot. The largest room in my flat is about 4.5-5m to 4,5-5m size. I may put it in the kitchen, although it is smaller in size but much cooler (away from steam sources).

On their website BA offer X3s for immediate shipping. It means that they have them in stock.

Where did you read this?

Quote from:  BA website
>>>> We are still manufacturing this item, it will not be shipped immediately <<<<

If they don't have them then they shouldn't post as "in stock" but as "pre order".
Also in description it is still written that this pre-order is long due "This is a PRE-ORDER (Batch 2), available for dispatch around 15/05/2014".
Also they already shipped miners to Minersource. They have not posted any updates for weeks and completely switched off customer service 2 months ago.

Nice chart. Thanks.

There is misprint about Bitmine Desk. They have never shipped Rigs but they are shipping Desks. 1TH/s for $1,599.00

I have 9 Rigs in my possession, so they have shipped some....

They may had shipped some after mid June.
When I received my refund for the Rigs in the end of May there were still no Rigs and they were shipping only Desks.
Anyway ,they are not selling any Rigs but only Desks. And for $1,599 not $7,000
