Hey Phil,

with all respect to this thread, and hope this isn't a highjack but i thought i'd post here because i'm having a similar issue. Trying to power 4 pandaminers B3 Gen 1's

would you recommend using a 6-20P to L6-30R Plug Adapter Power Cord Adapter if you have something like this?

or would you just change the receptacle to an L3-30R Receptacle entirely?

Would greatly appreciate the help and send some coin over as well! thanks

Why not just split the power between several smaller circuit breakers, like 16A?

That's way cheaper than a big PDU especially if you're not interested in PDU features.

a 20 amp 240 which derates to 16 amp does 3840 watts or 3 units at 1100 watts he needs

four of them to do 12 units. he needs 12 receptacles 3 for each circuit breaker a lot of hard wiring your way.

these items work at a low cost 3 hard wired receptacles can do 15 units.

Hope I am posting the in the correct forum.

I need help to wire my 10 L3+ Antminers.

I would like a diagram that I can present to an electrician.

The farm will be setup up in my home in USA so 120v with standard 15 amp breakers.

The diagram should be scalable for when I inevitably add more miners.

I'm not opposed to adding bigger breakers, safety first efficiency second.

I will compensate you with BTC for the diagram if it is legit.

Thanks in advance.

here you go you want 2x 30 amp 240 volt put in

use 10 gauge wire use 2 pole breakers.

have two l6 30r one for each circuit

use 2 pdu's each has 4 plugs and can do 24 x 240 volts =

http://www.ebay.com/itm/HP-Hewlett-Packard-228481-002-Module-PDU-Control-Unit-200-240VAC/261469140311?

use a few of these on each pdu
http://www.ebay.com/itm/HP-modular-PDU-extension-bar-p-n-228480-002-BEST-PRICE/272270265827?

lastly get some of these

http://www.ebay.com/itm/LOT-of-20-IEC-C13-to-C14-jumper-cord-cable-5-ft-length-/232389461182?

1 30 amp circuit breaker to 1 30 amp receptacle to 1 24 amp pdu to 2 breakout extensions to your 6 power cords

do this one time for 6x 800 watt l3's
do this two time for 12x 800 watt l3's

if you want to send me coin here is an ltc address

We are working on a commercial 'datacenter'. We have 2MW of power. Just trying to figure out if I am going to be forced to buy the expensive PDU's at $400 per 10 servers or not.

I feel like there should be a cheaper PDU available. All its doing is taking 240v and dividing it to 11 outlets.

You're not taking 240V and dividing it - you're taking 12KW and dividing it. That's going to require 60A minimum at 240V, which is a lot of amperage. There are 60A PDUs available, but they tend to be a lot more expensive than 30A units. eBay has TONS of 240V/30A PDUs. Like most datacenter-grade enterprise gear, it lasts way beyond its warranty, so refurbished PDUs are a great option. If the wiring has already been run and outlets installed for 240V/60A, your options are narrowed quite a bit by what outlet/plug you need.

Also, please don't make your own as another poster suggested unless you are really willing to risk electrocution, fire, and death, along with being totally out of code and likely to have any insurance claims rejected due to that.

I linked him good 24/30 amp pdus for under 40 each on eBay.

Looking for a setup that can take 240v from a outlet and distribute it to 11 outlets which would each draw 1100watts each.

I know there are plenty of PDUs I can buy (or just use 2 smaller ones) but I dont need any of the remote switching gear. Is there a cheaper way to get this accomplished than buying a name brand tripplite/apc PDU?

A example might be something like this (which obviously will not work)

What I am not looking for is something like this:

yeah buy used on eBay I just wrote a perfect solution for you in my last post on another thread

i will link
the pdus I linked will do 24 amps at 240 volts 24/7/365 = that is 5760 watts they have 4 plugs that will do 1440 watts 24/7/365

if you want 1100 watts per outlet those hp will be fine you need 3 of them they are cheap basic sturdy gear.

you need 3 l6 30 r wall outlets
you need 3 30 amp 2 pole circuit breakers using 10 gauge wire

Building your own is an option. I made a couple of ~4.5kW ones recently, mostly because 20A circuit breakers are the biggest cheap ones around here, cost me like €15 total.

Subpanel with its own breakers and individual outlets. Make sure it's built to code.

You're looking for Industrial level equipment, so it's not going to be cheap. You need a 60 amp PDU to be able to deliver that many watts, those are not common and are expensive, even for non metered units. An even bigger issue is --- do you have a 60 Amp 240v circuit installed in your building? If you're in a normal home (USA at least) the largest circuit is often a 30 amp 240v line for a stove or dryer. 50 Amps is scarce enough and you may need to have an electrician install an additional service to cover that much.

How does this work? Wouldnt the circuit breaker and the copper wiring pretty much melt at that much kwh?

It pulls 240 volt from a 240 volt source which may be 30 AMPS @ 240 volts which would be 7200 watts.

I purchased and use this one - search ebay - 72A-130BMLEN-02 240V L6-30 12xC13 outlet PDU Zero U NetApp 150-00027+A0 - Tested

Just don't setup a two power supply setup on one rig like I did and plugged in one power supply to one circuit protected side and the other power supply to the other circuit protected side. fried 4 cards and think its because the ground difference caused higher voltage on 12v rail powering cards. Not sure, but the other rigs that have two power supplies are fine, but they are plugged into the same side of the PDU above.
