Topic: Where to find 220v PSU cables in the U.S.? - page 2. (Read 1338 times)

At bones972  your post will kill people please delete it I will alter my post as I see what has confused you.



HERE IS THE SETUP


A)  A 240 volt wall outlet with a 30 amp plug

B)  The dell pdu   derates to 24 amp for 24/7/365 run time.

C)  Two power bars each rate at   12 amps for 24/7/365 run time

D)   each power bar can handle 2880 watts of psus.

So  any way you add the power for 1 extension bar to stay under 2880 bars is okay   i.e. 1 rig at 600 watts 2 rigs at 500 watts a rig at 1100 watts adds to 2700 watts okay.

the dell pdu has 2 switches each one will do 2 plugs.

so one 1 side use 1 of the 2 plugs

on the other side use 1 of the 2 plugs.


half the load on the left on one extension bar.

half the load on the right on the other extension bar.

    I just want to make sure I am following you 100% on this...
I was wrong... LOL That's why I asked the question.

Thanks for the additional information. Sounds like a PDU is the way to go.

I am already talking with a licensed electrician. I just want to make sure I'm not going to burn my house down =)

okay a pdu like this is good

plug in 2 of these one on the left side of the pdu above and one on the right side of the pdu above.

you could run three 800 watt pc's on each one   total of 4800 watts.  actually more.

the pdu will do 24 x 240 = 5760 watts safely

each extension can handle 12 x 240 or 2880 watts

so  30 amp 240 wall out let is needed


A)   30 amp 240 outlet
B)    pdu max of 24 amps 24/7
C)  2 extension bars 12 amps each.
D) lots of psu's plugged in



you need an electrician to wire the 240 watt outlet

I am 90% sure this is the outlet you need

Wow, thanks for that information. Will definitely be looking into this.

Any particular reason why those rigs would catch fire in the first place? Do PSUs tend to pull more wattage than they need? Is that just because of a surge?

Speaking of surge, does the PDU do surge protection too? Do I need to do something separate for that?

There are a few different styles as you have seen, but for most home outlets I have been using something like these: http://www.homedepot.com/p/Leviton-20-Amp-250-Volt-Straight-Blade-Grounding-Plug-Black-White-5466-C/301304708

You can also buy the matching receptacle. http://www.homedepot.com/p/Eaton-Commercial-Grade-20-Amp-Straight-Blade-Single-Receptacle-with-Side-Wiring-White-1876W-BOX/203492426

While they look similar to a 110V 20 amp plug and receptacle, the blades are reversed, with the positions switched so a 110V will not fit a 220V and vise versa. Since you will use only half the amperage when running at 220V then you would at 110V, you can probably run 4 or 5 rigs per 20 amp circuit.

An alternative and what I also do, is run a few L6-30R twist lock receptacles to the garage feed off a 30 amp 240V breaker and then plug a PDU into it. This way you can pull up to 24 total amps safely with the entire PDU while further protecting each individual outlet down to a more safe 4-5 amps. The danger with the first method without a PDU is that the circuit would need to pull close to 4800 watts before tripping the breaker, and in the case of only one or two rigs would most likely mean they would be on fire first....

These PDU's and cords are often used in server setups and both the PDU's and server cords can be found on ebay. Here is the first result I could find, simply to illustrate what I am talking about as I do not know or vouch for the seller: http://www.ebay.com/itm/APC-AP7841-Rack-PDU-Metered-Power-Strip-Distribution-Unit-30A-200-208-230-240V-/322503049461?hash=item4b16ae00f5:g:duwAAOSw~AVYqTn2

I do have a couple of APCs like the one listed, and they can be individually turned on/off via a web interface as well as they can individually trip if the outlet would overload at a much lower amperage as stated earlier. If you plan to do many rigs this is probably the better way to go.

The server cords with the correct ends to fit the PDU also can be found on eBay (again first result I found, no affiliation): http://www.ebay.com/itm/6-foot-IEC-320-NEMA-C13-C14-10A-18AWG-PDU-to-CPU-AC-Power-Cords-/262844530164?hash=item3d32c13df4:g:BsQAAOSwtfhYnCQc

220v in the U.S. is weird. There are a few different plug styles depending on how many amps it puts out (15,20,30).

I'd like to switch my miners to 220v because it's more efficient, but I can't find any cables. All of my PSUs do up to 240v.

What plug styles are people using? Where are you getting them?
