so I got my hands on a few cheap metered APC pdus :
Input: 208V , Connection: NEMA L6-30P , Cord Length: 12 feet
Output: 208V , Connections: IEC 320 C13,IEC 320 C19


I have an electrician coming in to wire to new cicuits for  and he said this :

Now, are these dryers and or ranges you are installing?  Do you have the model numbers?  The old 3 pronged outlets are grandfathered in for repairs only, but for new installs you need (and probably want, for increased safety reasons) 4 prong outlets. This requires 10/3 wire (which has 4 conductors) as opposed to 10/2 (3 conductors).

my questions to experts here :
-the NEMA L6-30P is three prong, but really only good for pdu's and computer stuff, should i let him do the 4 prong outlet and look for an adapter ?

-I don't want to pay another $100 for an adapter for each outlet.  he said something about buying pigtails from APC to convert the outlet but that looks expensive.

-Anoying thing is do wire up the  NEMA L6-30P, seems to require a permit pull which i don't want to pay for.

There should be no problem installing a NEMA L6-30 outlet in a home or business without a specific permit. The outlet is about $50 and the wires to your fuse panel maybe $3/foot. Circuit breaker is about $40. If it's a simple run without cutting holes in walls or running wiring through tricky spots it shouldn't be any more than $350 installed for a 30ft wire run. If he quotes higher get someone else to give you a quote or do it yourself if you have basic handyman skills. (remember electrical safety rules and shut off the main panel before touching wires)

Yeah your right he  quoted me $325 using his breakers , the outlets were around $19 a piece the wires were expensive though I had to buy 100ft since they run in 20 50 100ft increments.  We will see how the install goes today
and thanks.

Does anyone know if there has been some national holiday in Israel since yesterday?

No more holidays in Israel for the rest of the year.

http://www.timeanddate.com/holidays/israel/

(New Year's, Rosh Hashana, starts on September 25th.)

I asked because no one has been responding to my e-mails for last few days :-)

nobody responded to my emails, but they send me email today, so I guess that they have a lot of emails.

We are contacting each and every customer about their compensation, responses will be a bit slower than usual this week.

Your patience is much appreciated.

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.

Hey, we've got a p2pool node up for testing. Anyone want to try it out?

74.82.237.66:9332

0% fees, 0% author contribution, hosted in central WA on one of our 100 Mbps symmetrical fiber links. IP address will change eventually, and we might be rebooting it, so don't expect it to be reliable just yet.

Glad to see another doing this. We offer it as a option as well, and its a great contribution.

4 prong outlet is where the NULL and the GROUND are different.Mine are shunted. If in your case, they're the same like mine, you can use the three prong.

https://bitcointalksearch.org/topic/m.8182756

See there in the panel drawing the difference between a 3 wire and a 4 wire circuit. The three prong connector can be used in one of the two cases there where you bring the null or the ground to the device. What you bought there is a 208V rated PDU, intended to be used with a 3-phase service. Have a read on it if it's good up to 260V.

Just tell the electrician you need to power a computer. Not a dryer. The computers have 3 pins for power and there's no reason to install 4 pin sockets.

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

you're right but not the way you understand it...

kW/h*h = kW

Quote
1 SP30 = 3kW/h

To calculate consumption : consumption = energy used over time x Time
So the SP consumption Kw/h will be : 3kW/h x 720h = 2160  kW

This calculation is correct; With may just notice that K upper case is for Kelvin (temperature), 'k' lower case is the right one for kilo; And 'W' upper case is the right symbol for 'Watt'...

This sounds about right. ~220$/month.

Run a Bitcoin node.
I bought them from a UK company, who shipped them to me on the other side of the world (New Zealand). You can see prices on their web site: http://www.acoustiproducts.com/en/ucoustic_active.asp The one in my video is the Wood panelled product (in Maple).

So you go the big one? But the site tells "providing a thermal load capacity of up to 7.2 kW", so that's no more than 2 x SP30/31 with 1200W left for a S2/S4 at best. So why did you go for the big one if you can't put more in due to thermal load restriction?

I'm anxious about the video.
I started work on my cellar (basement) project near the start of this year. This was before Spondoolies-Tech came onto the scene. The cabinet is designed for normal IT gear, 7.2kW is plenty for 24U worth of modern energy-efficient servers... not so good for modern bitcoin miners.
