Hi Everyone.

Thanks for answering a noob question!  I've been mining with little R-Boxes for a while (6 of them) and had made enough BTC to buy an S9 straight from Bitmain.  When I got it in the mail, I opened it up, plugged in its PSU - but it wasn't enough to power the unit.  Only then did I read the instructions, which wrote:

"The AntMiner S9 total current is 20A, but most home outlet power sockets supply only 10A."

Breaker and Wiring?
I have lots of spare room on my panel, so I was going to get an electrician to come down and install the adequate line -- what do I ask for?  30A breaker on 220 with 8 gauge wire?  That ought to be good enough for one miner right?

Power Cable?
Lastly, the Bitmain PSU has a C13 looking plug, but should I be looking for a C15/16?  Anyone have a good line on a NEMA to C15/16 cable?  What have you used?  I found this link, which seems to be "right"?  http://www.lockingpowercords.com/products/987-l6-30-c15.aspx

I've read a few horror stories; are these things a fire hazard?

Thanks for your advice!

I believe that the most common outlet in North America is 15 amps at 120 volts, depending on the power supply that you received, it may not start below 205 volts.  The newer ones operate on 120 as well however only deliver up to 1100 watts on 120.  S9 total current should be around 12 amps at 120 volts or 6 amps at 240 volts.

Wire gauge size depends on amperage and resistance, an electrician should be able to determine an adequate sized wire for you application. 30 amps at 220 volts can safely power 3 S9 miners, at 240 volts you could run 4 S9s.

Your cables will depend on your pdu, either a c14 to c13 or a c20 to c13.

They can be a fire hazard if you don't understand electricity or if you overload your circuits.

The easiest and best way to do it, IMO, is to get a 30 amp 240v circuit installed, to a 30amp plug.  Then you buy a 30 amp 240v PDU, and then plug your miner into the PDU with the appropriate cable !  like APC AP7841

Are you planning to run just one or are you planning to get more?

If it's just one and there's no 240V outlet available, a Quick 220 would probably be cheaper than getting a new outlet installed.

This has all been already answered here How do you power an Antminer S9 in USA / Canada with 110v?
Post #42 covers the cords.

Thanks for the replies everyone!

I've got an electrician coming down - I'm going to do a 240V circuit w/30amp breaker and a Nema L6-30P twist-lock with the matching 6-30 to C15 cable.  Here goes!

Thanks for the help! 

It's time-of-use billing for electricity here; is there an API or control system to make the unit sleep during peak hours?

Stupid question; The Bitmain PSU I have (https://shop.bitmain.com/productDetail.htm?pid=00020170524082422857fCitO7c806A2).  Would both a C13 or C15 fit?  These two female plug types are interchangeable?

Sorry, next question - would this unit work? It says it's rated 208V

A) refer to the Stayonline link I gave http://www.stayonline.com/208v-straight-blade-cords.aspx The site explains everything you ever want to know about cords & plugs...
B) Maybe try reading specs and not just the product sales description? The PDU link you gave explicitly states it works with 208-240V  Roll Eyes
btw: A free tip -- check that link to see what kind of outlets the PDU has and make sure you get the right cords to plug into it and the PSU's.
