Electrical wiring for mining

[PharoahzServant]

Please help,

I wanted to give my antminers 220v power.  I was told that there is a way of wiring up 110 outlets to deliver 220v by just putting the second phase of power on the neutral screw and not using the neutral wire at all.  I had 12/3 wire  and  did so and they did not turn on, I’m not sure why. The wires are brand new, the panel is brand new, the breakers are brand new.  The outlets are brand new as well.  Can someone please help and give me direction? If the outlets need to change please provide a brief recommendation as the type to purchase. Do the miners need to detect a neutral phase from the panel? Any assistance is greatly appreciated.

DO NOT DO THAT!
Yes it *can* be done however it is an extremely bad and unsafe idea.
If you want 220v then hire an electrician or take a small elect course at your local home improvement center and do it right.

Im definitely seeking consultation on here.  I have ten years experience in the contracting files that. Includes basic to intermediate electrical wiring. I’ve run the riser to the panel myself. I’ve installed the breakers myself and I’ve run the home runs myself.  I really just need some recommendations as to which double pole 20 amp outlets to buy or how to wire these 110v outlets. Thanks so much

Which 220v 20a outlets to buy depends on what your country uses:  schuko? NEMA? Other? Ref this list here As for wire gauge, again all depends on what the standards are for your country.

As for 'consultation' here in the Forum: Because of liability concerns NO professional electrician or EE should be giving advice to the general public in a Public forum because if something goes wrong its OUR ass that can be on the line and facing a lawsuit. Aside from that, advice from an unknown non-professional must only be treated as their opinion which means it is not necessarily correct. Their opinion might not be wrong, just be sure to check the information against several sources to see if it jives.

If you have a tester you can check touching both "hots¨ from each phase and that gives you 208v. But in countries like USA they give 120 step down from 240 for whatever reason and not different phases unless its a commercial/industrial setup. There is also another setup with 480v/277v

I can understand the fear of Lawsuits but that stops the second you say " This is not instruction or advice to undertake this project, this is an explanation of what is needed.  Please follow all local regulations and consult a professional. "

I got a lot of advice from people when i first got here between that and google i went for it and then ran ideas by a few electrician friends to be sure. I advise you to do the same with anything you get here... not the guy who told you to do the magic 220 with 110 outlets though, they crazy.

Now my ticket doesn't rely on any of that. I'm assuming North America so yeah a 2 pole 20 amp breaker works for a couple antminers depends on what model and your line voltage. You need to check what brand of breakers are in your panel currently and buy that same brand. For me it's stab-lok. Then using 12/2 will be more than enough for the 1 line but allows you to upgrade later if you choose to say a 30 amp circuit. The receptacle depends on what you are using a PDU or just the power cord from 1 power supply - likely a nema 6-20.

Being a contractor I assume you have an electrician buddy or 2 buy them a beer for their ear and you could have this banged out in under 2 hours.

Not quite. You have 220/240 in your home for the electric stove,  clothes dryer, A/C unit & ....

While there is a step down transformer on the pole (or in a box) for distribution lines at 13,800 volts (typ.) down to 240 secondary side, there is a center tap to get 120 from each leg to the center tap for the 120v  "neutral".
