Title: Question For Miners Using 220 V or 230 Volt... Post by: BitcoinIntern on September 25, 2017, 04:40:27 PM 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. Title: Re: Question For Miners Using 220 V or 230 Volt... Post by: NotFuzzyWarm on September 25, 2017, 06:18:56 PM 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 Title: Re: Question For Miners Using 220 V or 230 Volt...

Post by: philipma1957 on September 27, 2017, 10:18:30 PM 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 4mm˛ cables. Check if cable and connectors get warm. On single phase, please ground your equipment!

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.

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 .. http://ca.mouser.com/Search/ProductDetail.aspx?R=VL-0124-05-200virtualkey68600000virtualkey686-VL-0124-05-200 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...
