Question For Miners Using 220 V or 230 Volt...

[BitcoinIntern]

Hello Everyone,

I have the below question for everyone running on 220 V or even 230 Volt current.

1) Are you guys using "Phase to Phase" or "Line To Neutral"?
2) Dumb question: The machine is single phase...right?
3) Can you run it on "Phase To Phase" 208 V current?

Thank you everyone.

Major hint:
If you are going to be fiddling with running AC power yourself - go to Home Depot or such for one of their DIY classes and LEARN THE BASICS OF HOME WIRING!
As a 2nd, choice, at least look up AC power on Wikipedia.

Questions like this prove zero-knowledge and that = danger!

To directly answer: In North America when using 220V both are a 'line'. For homes with split-phase it is the lines across the Neutral tap/split or phase-to-phase for 3-phase. The N designation on a PSU input is does not apply - it goes to a phase. All a PSU or such cares about is that it sees 220v across its inputs

Thanks notfuzzywarm 

please remember

a 30amp  240 volt line  will max at 30 x 240 = 7200 watts.
a 15 amp 120 volt line will max at 15 x 120 = 1800 watts.


that is 4x the energy  so do not shock your self fucking with it.

treat it with respect.

At 7200W keep a close eye on the wiring. Use at least 4mm² cables. Check if cable and connectors get warm. On single phase, please ground your equipment!

6mm² wires preferably.

The wiring must be sturdy. Besides the normal use it must also withstand the short-circuit current in case of a fault.
You don't want it to start a fire.

In North America..wires are standardized by GAUGE.....18,16,14,12,10 etc...

220v is used exclusively for HIGH AMPERAGE.....20, 30, 40 amp are most common usage for home and light industry

I have NEVER seen a 220v line smaller than 14 AWG (Note 16 AWG gauge is SMALLER wire than 14 AWG)

AMPERAGE will usually dictate which gauge you MUST use..
40-60Amp heavy commercial welder uses 10 AWG
A 30 amp line is VERY common for stoves..Dryers. large A/C.. it usually uses 14 or 12 AWG...

MY power cable for my Bitmain PSU's are ..

They are Hospital grade.. rated for 16Amps and 220v ....They have a C13 end for the PSU ..the other end I cut off and connect bare wires  to my 30Amp line in a junction box
No PDU... NO plugs needed
