Indeed agreed.....But I still wish to promote the idea of miners being self sufficient and independent and should know ALL aspects of their mining op..

There is a FAR cheaper and easier way....NO plugs..NO PDU's..perfectly safe and legal...EASY DIY.
First..220v PSU's are FAR more efficient and effective and more durable..
Asic draw so much amperage 220v is a FAR wiser choice..
30Amp 220v Breakers are VERY COMMON and cheap and easy to DIY lines to junction boxes to connect PSU's

Easy for you to do or for me to do.
Not so easy for the op.
Pdus are far better for the op.
I prefer pdus for labor and time saved.
If I wire a 30 amp breaker to separate plugs. I need to spend the time and effort. The op does not have this skill set . If you read his posts do not tell him to wire circuits it is unsafe for him to do it.
At op 500 for a long run of 6 gauge is not terrible. Depends on labor and how he grounds it.
10 gauge for a single 30 amp I have seen quotes of 200 to 400. Depends on length and labor.
A 250 ft roll of 10/3 wire is about 200 at Home Depot. Two receptacles are about 15
The breakers are 20
That is about 235 a few junction boxes and parts are about 245.
It is not a days labor so if it is him with an assistant maybe 600-700

phillipma1957 - you are the bomb! I did not explain myself completely. Luckily I have just been in "talks" with the electrician and he has not done anything yet. Also, I havn't purchased the PDU yet. My only real fuck up was purchasing the two 120v power supplies from minerwarez. Ugh, oh well, I can probably just throw them on Ebay.
Ok, you have set me straight and I appreciate it! I will talk with the electrician about running two 30 amps. btw - he did recommend using 6 gauge wire for a 50 amp. Anyway, I will find the PDUs I want and show them to the electrician.

look above those you purchased from minerware will work
now get some of these from parallelminer
use slush for a discount 1 will run 2 avalons

each pdu can do 5200-5500 watts
4 avalon each pdu 8 avalon total balls to the wall +1
Just to wrap this up. I want to thank everyone who chimed in. I will send pics during setup and after. I will follow philipma1957's instructions. Thanks again for all your help. To answer that last question about the PDUs I already purchased, I made yet another mistake. I thought they were 120v only, but it looks like it also supports 240v as well: https://minerwarez.com/collections/psus/products/1200-watt-psu-with-breakout-boards-and-pci-e-cables So, long story short, I will go back to the electrician and get another quote to run two 30 amp lines which terminate into the two L6-30R outlets which philipma1957 recommended above. Also, as an FYI my electrician was going to charge me $550 to run the 50 amp line. That included 75ft of #6 cable and about 4 cuts (within my house), and "tie in breaker, and computer rack". I thought that was pretty cheap, but I don't have a ton of experience w/ electricians. I will go back now and see how much he will charge for the two 30 amp lines.
Thanks again!

I am a noob starting an in-home mine utilizing 5 Avalon 741s. I've posted previously and gotten some great feedback. But now, I'm realizing that I don't fully understand something which is probably fundamental. Here it goes...
So, I've talked to an electrician. Because I will need to consume about 5500 watts for the 5 Avalon's, and because I would like plenty of room for expansion, we agreed to run a 50amp 240v line from my subpanel. If my math is correct, this should provide 50x240 = 12,000 watts, right? Now, here is where I get lost. Rather than having the electrician create a bunch of outlets for me, I want him to install a PDU. My questions are:
1) I don't know much about PDUs. Can I throttle each "outlet" on the PDU to be 6 amps X 240v to give 1440 watts per outlet?
2) If I go this 240v route, does this mean I cannot use two 120v Avalon power supplies which I already purchased? My power supplies will have to be rated for 240v, right?
3) Can anyone recommend a PDU to plug into my 50amp 240v line? Should I be looking for 1 or 2 pdus?
I'm kinda lost on PDUs.
Thanks,
Steve

FIRST.. you cannot plug your 120V Avalon power supply to your 240V electricity supply.. you're gonna fry that in an instant. Check first your AVALON POWER SUPPLY if it is auto volt (110V ~ 240V). IF it is not, then you will be needing a step-down transformer (240V-120V) in order to operate your 120V avalon power supply to your 240V electricity. OR you can change the avalon power supply to be a 240V input supply. Check which way is cheaper.
Check also the power rating of the PDU how much power it can handle. Do not overload it, it will blow its fuse, worse burn it. Just follow the post above of philipma
missed the 120 volt psu's
op link them please.
avalon listed these at 176-264 volts
https://canaan.io/product/sorcerer-power-supply-unit/
minerwarez have these at 110-120 to 200-240v I know these work ate 120 and 240 I have them
https://minerwarez.com/collections/psus/products/1200-watt-psu-with-breakout-boards-and-pci-e-cables
i know these work at 220 to 240
https://minerwarez.com/collections/psus/products/2400-watt-psu-with-breakout-boards-and-pci-e-cables
so what psu's do you have?

I'm not getting it. Which country? Why do you want to run it on 240v? to save a power supply?
Lol. Yes, I probably did fuck up. But I thought a PDU had the ability to fan out power? TO basically control the amount of power to each outlet on the strip, no?
I'm wondering based on your post has the electrician already installed the circuit, as it sounds like maybe you've only discussed it with him. Maybe it's not to late. Because there are better options.
Personally I would think about 2 30 amp circuits running into the space.
I remember your last post, have you thought about how big you want to go overall?
Lol. Yes, I probably did fuck up. But I thought a PDU had the ability to fan out power? TO basically control the amount of power to each outlet on the strip, no?
no that is really costly and not needed for mining.
did he put in the circuit?
did he use 6 gauge wire?
what does the receptacle look like?

Let's go slow.
You fucked up. ------- slightly
Give me a minute to go to a real pc.
You need to understand this very simply a pdu is basically a power strip. that safely derates the circuit breaker 20%
so a 30 amp circuit uses a 24 amp pdu which allows for 5200 to 5500 watts safely
there are endless quality 30 amp pdus on ebay for 50 bucks
they will do about 5200-5500 watts safely 30 x 240 = 7200 x 80% = 5760 watts max 4 avalon 4's at full power 5 at -1 or --2 setting.
if he put in a 50 amp circuit you need a 50 amp pdu and did you see if he used 6 gauge wire to do it?
50 amp pdu's cost big money if new over 300.
a 50 amp circuit was a mistake but you did it.
but luckily here is a 40 amp pdu for sale
http://www.ebay.com/itm/HP-417587-D71-PDU-40AMP-High-Voltage-228481-007-376274-001-/152703430194?
it can safely do 40 x 240 = 9600 watts
and since you are 50 amp circuit 50 x 240 = 12000 watts x 80% = 9600 watts
so that works
now look at that pdu and buy it show the plug on it to the electrician and have him hook it up.
then buy 4 of these
these can do 2400 watts each 2 avalon 741's each
http://www.parallelminer.com/product/power-supply-kit-for-2-antminer-d3-dash-miners-94-platinum-high-efficiency-200-240v/
so that is 4 x 2400 = 9600 watts
the fuckup you did is not too bad. but I can not see the plug on the pdu to tell you what plug to use.
I told you get the 24 amp pdu's but you did not listen.
If you really wanted more power he could of run a 60 amp sub panel with two 30 amp fuses
you then could have had 2 pdus each doing 24 amps total of 48 amps or 48 x 240 = 11520 watts max
