I called an electrician and told him.. He's the one who advised me to add these new sockets. I'm guessing he's not a qualified electrician. Is there anything in specific I should tell the electrician?
I'm not good at electrical wiring. Maybe someone else can help you, but I would tell him: "Yo dawg I need to plug 6 cables that will suck 1500W each. Do your stuff and I'm paying!". haha.. Cant I just put an extension with 6 extra sockets type thingy and connect the machines to that? You use a PDU (big ass power bar rated for the proper amperage) and plug your power supplies into that. I have 30 amp PDU's connected to a 240v outlet. This allows me to run about 5800 watts of the single plug. Much more cost effective than pulling more copper and having multiple outlets at the wall.

Im in the UK You want to go with what wpg recomends, your going to want dedicated 20/30A circuits @ 220/240 for each SP30 you have, cheap NEMA l6-20r or l6-30R pdus can be had for less than $100 each

Ok, I'll look into getting a 30AMP PDU in London. So i can connect that directly into my socket. Will this be enough to plug 2 or more SP-30s?

The PDU will not magically improve the maximum power you can draw from one line. If you are pulling too much power, it will trip that circuit´s brakers and it will turn off. You still need a total of around 45 Amps power (including safety limits), and I don´t think one circuit (without any modifications) will be able to provide that. I guess standard circuits should allow ~16A of power draw.

@boscocoin
That AC is barely enough for ONE sp30.
When you say "in your room" I hope you do not mean that you will be staying in that room when the units are in there?
Evacuating 3kW of heat from a 2U case produces a significant amount of noise....
These sp30s are optimised for datacenter performance and not meant to be a home solution. They can be a home solution with proper AC / airflow engineering, but hardly in a closed room.
Apart from the fact that AC equipment is expensive, running it also adds to your electricity bill, and unless you get WA state power rates, that will mean a big increase in your hosting cost.
Wow. Noise can be mitigated by buying an expensive ($5K) cabinet, but heat? people just look at the production numbers and don't think about heat, which is a MAJOR issue (for home). Ok I guess I will need to find a cheap hosting place in London. Anyone know any cheap ones in London I could go with? And the average costs per month including electricity? Hi, I'm from London too. There is no good data centre in London. I e-mailed 2 of them some time ago and non of them replied to my e-mails. I recommend Advania or some other sustainable DC in Iceland. Especially if you care about the future of planet's environment. They don't use ecocidal energy because their electricity comes from sustainable geothermal power plant. You could easily plug 2 x SP30s in your house but you just have to watch the wattage for specific circuit. It depends if you have 16A or 32A circuits. Maybe even 3 x SP3-s if you use PDU and manage to arrange the power properly between different circuits. For example I have got: Main lights: 6A Rooms' sockets: 32A (Provides 8000 Watt) Oven/Cooker socket: 32A (Provides 8000 Watt) Kitchen sockets: 32A (Provides 8000 Watt) Basically, I plugged 2 x SP30 into my room sockets which sucks up 6000W. Then I plugged surge protected extension cord to my kitchen socket and dragged it to the room so I could plug another miner next to the others. You just need to be aware how much power your other appliances consume. Lamps plugged to sockets consume very little power so you don't have to count these unless you have 20 of them switched on around the house at the same time. When you are planning to use vacuum cleaner then switch off the computer and TV. Or, for example, when you use microwave or electric kettle then don't use hairdryer etc. It all depends to which circuits appliances are plugged into and how much spare wattage you have got left. My fuses never went off.

We have 240V/50Hz single phase (13A circuit breakers) and 400V three-phase (= 3 x 240V/50Hz with 16A circuit breakers) current here in Europe.
Any specific recommendations for PDUs running on a single phase 240V and three-phase 3 x 240V?
So a single 240V 13A circuit gives me max 3120W, and I'm wondering if there are PDUs allowing 400V three-phase or more than one 240V single phase input.
I may have to let an electrician come anyway, I think it's best to upgrade a few 13 circuit breakers to get more juice throughput, but I better have some info in advance, and I'm wondering if using a PDU is beneficial.

Ok.. Hosting seems to be bit expensive.
I'd check the sums again, all mine have gone to the USA for hosting and it's cheaper than the UK in all respects For a start you save the 20% import duty, 2x SP30's at say $4500 each works out around £1,100 total. If they go to the USA you pay 0 Typical UK Electric is around 15p, using 5400 watts is around £20 or $32 A DAY, $944 a month Where I host my machines you would pay $700 a month, so your saving $250 a month in hosting and the $1760 import fees, you don't have to worry about power/internet or cooling and you have full access to the machines and can make any changes.

1) 13a at 240v with 20% headroom for 24/7 use and surges gives about 2600w usable. I would not load anything over 2800w or you'll trip breakers or risk fires inside your walls. 2) PDU doesn't give much real benefit unless using with 30a or specialty outlets. Just use the typical 13a style of outlets and wiring, or 20a version if possible. Use normal surge bars that are far cheaper than a $100-300 PDU and take way less space.

I just vent my miners out a window. The screen protects the miners from a squirrel making a nest in them. No need to pay for cooling. I've done it for over a year now with no issues other than noise, but these days I'm running S3's which are very quiet. Probably wouldn't work with the jet engine noise level of the SP units. Unless you live away from other people who would complain.
Funny how no one seems to worry about intruders pushing through the screen and sending the miners tumbling to the floor. And then stabbing you in the eye while you sleep. ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) Someone broke into my garage a couple of months ago. They then tried to enter the house through the inner garage door which was locked. Luckily they ignored the 2 Super Jupiter modules that I have running in the garage and were unable to get into the house. Instead, they took a couple of cheap power tools, lol. They could have taken the S1s, BFL Singles and the dozens of USB sticks and I wouldn't have cared since they were just collecting dust.

Keep the hosting contract as long as they're profitable. If they're not longer profitable, try to sell them outside UK and you'll never pay the VAT. The guy who's receiving them will pay duty fees if outside US.

My pleasure, there is no fixed contract with the company I mentioned you just pay monthly and can cancel anytime. I intend to sell mine to someone in the USA when I no longer require them as again you'd have to pay the 20% if they come back to the UK

Just took a look, according to the numbers for a SP30 that's $0.1960/kWh, which means impossible to reach a positive ROI if you put that price for energy into any mining calculator. I'm struggling with 0.1093 €/kWh ~ 0.1416 $/kWh (that's excl. VAT) because still no positive ROI with any of the current machines, so I have absolutely no clue how you guys are doing it. I thought Iceland has such low energy costs that it may be worth it, but even offerings from data centers there are pretty much out of question according to my calculations.
