Powering one of these in US residences will be tricky at best. The optimal solution is if you've got a 240V / 30A circuit, which would supply 5760 watts continuously (80% of 7200), so you could drive 2 on that circuit. Otherwise, you're going to have to get creative. The typical household breaker is a 120V / 15A, which will give you 1440 watts continuous power (80% of 1800).
With the SP10, the firmware limits the PSU (but you can override it). I'm wondering if the same will be available on the SP30. Again, basing this on the SP10, the typical limit of the AC2DC is 1260 with DC2DC set to 62. This might be different on the SP30 because of the different PSUs in the unit. Anyway, what I'm getting to is that if you want to run this in a US home and do not have the 240V / 30A circuit, you're going to basically fully utilize 2 standard 120V / 15A breakers to power a single unit.
So, if you've got the space in your breaker box, your best bet would be to get in touch with an electrician and have a dedicated 240V / 30A breaker installed along with a NEMA l6-30 outlet, and then getting a decent PDU to plug your SP30 into.
but each power supply is separate 220v plug ...so I would need 2 220v breakers 1 for each plug that wold be 1250w so I should be good that way if I put one on each breaker ie 1 for each power supply 220v circuit that is
I could run I guess from what I've read both on 2 120v circuits but I have to run the lines anyway
to expand below (my convoluted logic)
here is an online calculator the below using BOTH of the power supply plugs to 1 220v circuit 20amp ..even that should work fine I get this
http://www.supercircuits.com/resources/tools/volts-watts-amps-converter220v 2500 watts is 11.3636 amps
So a separate 220v 20amp circuit for EACH of the power supplies on the sp30 for one of the two according to the above calculator link I'd get this
220v 1250 watts 5.68181 amps
http://www.supercircuits.com/resources/tools/volts-watts-amps-converterif I ran both on above calculator at 120v/20 amps I'd get the following
220v 1250 watts 10.4166 amps
so anyway looks to me I should just run both of the power supplies on an individual 220v breaker 20 amps probably using this on each of the lines to be safe
triplite isobar surge protector 220v from amazon
http://www.amazon.com/Tripp-Lite-ISOBAR4-220-Protector/dp/B00006HZ4Nand all should be well?
unless you really should run this beastie with both power supplies on the same circuit? I guess it looks pretty obvious above in that
I have the space on the breaker box and it is right next to this breaker box...not too much work
or am I missing something here as mr. obvious? ie is it still better to run the above on 1 220v circuit (both power supplies) even considering the other choices?
ie I'm over thinking this and all will work ok on a 20amp 220v breaker regular 220v plug/line again both power supplies same circuit
seems like 2 wire runs is better but again wtf to I know

Kinda of an odd question...but the sp30 is 220v and has two power supplies....as long as I'm setting up outlets and use two surge protector strips?
or would I be better off running each power supply off a diff circuit (ie 2 sep 220v circuits) (ie probs with one 1/2 the sp30 will hash? does it even work that way?)
or just have one 220v plug...stick the ISOBAR 220v tripp lite surge bar on that and plug the 2 plugs off the sp30 into that all one 220v circuit
or hell either way works?
just wondering wtf got the wire and the distance an't so far as to do 2 individual 220v plugs to the miner
I'm in the USA by the by

If you are going to use on 110V, 20AMP will not be enough. These beasts are proven to provide as much as 1400W per PSU. 1200W is nominal for 6TH/s, as 1000W is for SP10's 1350 GH/s.
I assume you would be willing to overclock it, at least in the beginning, so consider having your wiring capable of handling some 2800-3000 watts. If it is 110V, you will need 30A, on 220V you are looking for 15A.
Both PSUs (Murata and Emerson) tested successfully at 1400W under 220V.
We will draw ~1350W from them to leave us some margins.
The final results will depend on system behavior of course. The above are estimations.
ok just saw your post see my above posting ...again if you are correct then 2 220v 20amp circuits (one for each psu) should be adequate
again I could really be missing the boat here)
1400 watts each psu (each on its own line) at 20amps would be using this calculator
http://www.supercircuits.com/resources/tools/volts-watts-amps-converter220v 20amp would be 6.36 amps per circuit (ie 2 of them)
anyway comments welcome thanks for the help ....corrections? I'm clueless?
