Yes, space in your panel (and therefore moving breakers around) can be an issue, but if you have space for sp30s available and decent power rates, getting some 220-240V circuits installed should be pretty straight-forward.
Hosting at home does help the most with decentralizing the network, but it might prove a little difficult to run more than one sp30 at home (although noise levels are much better than the sp10).
With the colder months approaching (atleast on the northern hemisphere), heat shouldn´t be as much an issue and some fans and an open window can work wonders.

CISCO PDU RP208-30-1P-U-2 74-8669-01 POWER...
I think the cisco would provide more power since it rates 200-240 output while the APC is 208V
PDUs are optional. Why not just use plain outlets? Maybe a NEMA 6-20P outlet and cable like this:I think the cisco would provide more power since it rates 200-240 output while the APC is 208V

In any case, the power you would get would depend on the voltage you actually supply to the PDU, not the voltage it's rated for. Of course, if you're supplying 240V and it's only rated for 208V, it might blow up or fail to work or something. It would probably be fine. Are you residential? Then you've got 230V or 240V single phase/split phase. 208V is what you get from 120V/208Y 3-phase power, which is generally found in commercial and some industrial properties.
*edit its a pain in the ass linking images in this forum so ill just use links *
Yeah im finding that out ..
so i paid an electrician off Craigslist to install two 30Amp outlets for me , and of course they were some early issues.
1. we found there was no space on my panel for two full size 30A 240v breakers so he had to shift many 4 of my 20A breakers into dual breakers and you can see below:
https://www.dropbox.com/s/31pb4jh8bux9p4a/WP_20140903_19_28_15_Pro.jpg?dl=0
2.he was worried that my 30A outlets i got were too low grade , I guess he had never seen these before ?
https://www.dropbox.com/s/hk70ueyyks5sfe4/WP_20140903_19_27_32_Pro.jpg?dl=0
Anyeays we got past that and we had it hooked up to a board 30 feet from the panel or so here :
https://www.dropbox.com/s/c8js4kztifqo46f/WP_20140904_01_40_25_Pro__highres.jpg?dl=0
finally i got it all hooked up to the Cisco PDU and plugged it in and started the SP30
https://www.dropbox.com/s/gawjkdj10jk6v2n/WP_20140904_01_41_02_Pro.jpg?dl=0
with nice results:
almost 4600 TH hash rate at around 240v on each PSU, total power used seems around 2800W

I'm thinking i can get more performance closer to 4700TH with more fine tuning but I don't know what settings to change since it all seems pretty much hard coded

You are in a negative position after spending .00135 because of the high hosting fees where spending .00150 brings you lower hosting fees. But this is an offtopic subject so I will not reply to it in the future.
People (mostly not RoadStress): Please do not respond to s1gs3gv at all. He is a well-known troll in this thread, and is likely paid by a competing manufacturer. Any reasonable person would also factor in efficiency (0.55 J/GH for the SP31 vs 1.0 for the S2) and hosting costs (about $100/kW/mo for the S2 system), which s1gs3gv does not, because his purpose is simply to spread FUD and derail the conversation.

My SP-30 is only hashing at 3003,08 Ghs 240V circuit any recommendation or help about this ?
Right after the miner is started, it will hash at about 3 TH/s. Generally, it will increase to around 4.4 TH/s to 4.6 TH/s within 20 minutes. This variance is due to conservative starting voltages, which minergate tweaks over time to optimize performance.
If your miner is sustaining about 3 TH/s, then you have a problem, and should contact [email protected].

For those with experience measure KW/hour costs. Could you please tell me if the following calculation is correct:
1 Month with 30 Days has 720 Hours
24h x 30 days = 720 hours
1 SP30 = 3Kw
To calculate engery : Energy = Power x Time
So the SP consumption Kw/h will be : 3 x 720 = 2160 Kw/Hour
If the price would be 0.1$/KWh then one would pay 216 USD per month?
Thank you
That will be your ENERGY charge.1 Month with 30 Days has 720 Hours
24h x 30 days = 720 hours
1 SP30 = 3Kw
To calculate engery : Energy = Power x Time
So the SP consumption Kw/h will be : 3 x 720 = 2160 Kw/Hour
If the price would be 0.1$/KWh then one would pay 216 USD per month?
Thank you
Most utilities will also charge you a capacity charge (many names for this) based on your peak demand for the month.
plus a transportation charge (for the lines etc.).
Then a whole bunch of other BS.
It does not seem significant but sometimes the demand/capacity charges can work out to several cents per kWh when you divide them over your bill.
Plus, on residential rates, most utilities have different energy charges for peak, shoulder and off peak hours.

Well, if I am in a negative position having spent .00135, I am in an even more negative position if I spend .00150.
And seriously, NOTHING beats a doorstop any day of the week, especially a door stop that cost you a couple of hundred bucks a month to host.

Why would I buy at .00150 (plus hosting) when I could buy at .00135 ? So that I could have a doorstop at the end of the day ?
Maybe because if you will not produce more btc that you bought "cloud hosting" for, then once cost=expenses, you will have negative equity and NOTHING else.

Err ... I thought this was the Spondoolies thread ... posts are going a bit AWOL ... 
Back to business, really happy with my SP30s, hashing on average (at toom.im) above 4.5Ths and had a very good day today with my pool.
Also had confirmation of coupon/voucher codes for the GB compensation, thanks Sponds, all looks in order.

So with the Oct. SP31 @ .00150 gh/s (BTC ~ 471, $3920, 5.5TH, excluding hosting) and the Bitmain cloud @ .00135 gh/s today,
are those of you pre-ordering SP31 machines getting a better deal than the website listed price ?
are those of you pre-ordering SP31 machines getting a better deal than the website listed price ?
1. price is lower with coupon, naturally
2. cloud hashing will end as soon as cost=earnings, and you have no residual rights (to machine)
i don't want to belittle bitmain, as I use them and like their equipment, but i see this cloud as a way for them to get rid of S2 just before the indroduction of something else.
Cloud hashing is for someone who wants to play with bitcoins a little without wanting to mine or buy through coinbase or other exchange.
And I very much doubt that the Bitmain cloud is based on the S2.
yes, it is (plus old A1), just check the relevant thread.

You are talking about the 'compensation' coupons, right ? They represent BTC or fiat already spent. Nothing free there.

Is the Cisco one with circuit breakers ? The spec says they're 20A .. so the whole PDU will power only one SP30 .. (2x8A max at the wall)
The APC one is METERED .. more value for the buck (i.e. you connect to it via SSH and can monitor the power usage). Tripplite sells those for $1500 ..
http://www.apcmedia.com/salestools/RZAN-7NWRWD/RZAN-7NWRWD_R1_EN.pdf << here's a picture for the APC one. If you buy it, ask for the passwords.
Argh thanks I thought even the APC unit could only do : 208x30A which would barely be enough to run two sp30s
So these Ciscos have 20A circuit breakers what is the point of that when it inputs 30A and outputs up to 240V.
I guess I need the metered one after all.
Thanks

Very good. I am using p2pool too, there are so many advantages - Low DOA, easy redundancy setup, low orphan block count.... And it helps to keep the network decentralized. Anyway the only difficulty, is the merged mining setup….
p2pool merged mining? I didn't know that was even an option. Any more info on that?
This is fully supported. Anyway, the local p2pool node has to find a block to get the merged coins.
Check out the following threads:
Complete Guide to Merged Mining and P2Pool
Setting Up P2Pool and Merged Mining in Ubuntu 14.04
Hope this helps.
