run 2 phase and drop a small breaker box at the other end. or #2 and become a /diy/ legend for being stupid. how the fuck do you get 250v single phase in the first place?

>>2786197
>2 phase
Terms that hardly anyone ever uses. Yes he technically will have 2 phases at 250v. Yet he still only has a single phase electric service.

You don't have severe autism do you?

>>2786190
In principle double neutral, single live earth would be beneficial, but in practice I probably wouldn't connect the fourth wire because if someone else ever goes to fuck with the cable, they could mess it up and make it dangerous.
>>2786197
Vast majority of the world has 250V single phase, 400V three phase.

>>2786190
Nowhere in the world uses 250v
You posted a cable with no Neutral.

I dont think you should be allowed near electricity.

>>2786201
The majority of the world has 120/240v split single phase, 120/208v 3 phase, 120/208/240v 3 phase, or 277/480v 3 phase, idiot

>>2786197
>2 phase
Not a thing unless you are an experimental engineer from the time of Edison. Its either single phase, three phase or split phase for Americans. You goddamn retard.

>>2786201
230 volts, if you are at 250 you are 3 volts from nominal failure and mandatory shutdown of most inverters and other smart devices. You are far too badly informed to be messing with electricity. Especially when you are pulling 4 x cables, instead of 3x or 5x which are the standards. You are using specialist machinery cables for domestic use because you are a retard.

>>2786239
Why are you pretending to be an expert when you clearly have no real world experience?

>>2786238
>split phase
This is the correct terminology.
The 2 phases coming in to your breaker box as your mains are out of phase by the standard 4/3 π radians. (I don't know what they do in Whereverthefuckistan, but I assume it's similar, unless it's one of those weird one-wire/earth-return countries.)

>>2786248
I am an electrician working with EU voltages. What the fuck are you talking about.

>>2786249
Split phase is unique to the USA, as Europe uses 230v single phase, which is plenty. Only reason the USA even has split phase is a cope to deal with their 110v net.

>>2786252
>cope to deal with their 110v net
110v doesn't exist anywhere but the load side of the transformer on the power pole. There is no "110v net."

>>2786249
>are out of phase by the standard 4/3 π radians.

gee prof, is that the same as 240 degrees? How is that different from 120 degrees, and do you actually have shit that runs on it? anyway, in freedomland split phase means 180 degrees, or exactly out of phase, which is derived from a single phase using an ordinary transformer.

>>2786260
>is that the same as 240 degrees
To midwits, yes. Except it's not that. Not even close. But good on you for using google.
>How is that different from 120 degrees
Well, 240 is exactly twice as many as 120, isn't it.
>in freedomland split phase means 180 degrees, or exactly out of phase
No it doesn't.
>which is derived from a single phase using an ordinary transformer
No it's not.

>>2786238
2 phase is a thing in the united states. rare, but mostly a product of an area being electrified before they could quickly and accurately calculate 3 phase loads, and they cant just rip all of the infrastructure out now and leave people without power until its rebuilt.

>>2786262
by golly i think you were wrong on every count there, professor. please give me your version of events.

1. google? everyone with a decent education can convert radians to degrees
2. you can't tell two phases in a 3 phase system apart, except that all three are 120 degrees apart. and if you know what that means, 120 is exactly the same as 240.
3. in freedomland our split phases are indeed 180 degrees apart, and are exactly out of phase. they come from a simple transformer that begins with a single phase. and if you are not splitting hairs, they are what I said.
4. this is getting old. are you actually trolling my ass off? if so, you got me.

>>2786266
>3. in freedomland our split phases are indeed 180 degrees apart, and are exactly out of phase. they come from a simple transformer that begins with a single phase. and if you are not splitting hairs, they are what I said.
split phase is not 2 phases that are 180 degrees apart, it is a single phase that is center tapped with a grounded conductor.

>>2786200
>Yes he technically...
No, he specifically won't. Single-leg, single-phase, 250V leg to ground.

>>2786236
From a fellow American to another: America is not the majority of the world. Most of Europe and Asia have single phase 240V, no split-phase business.

>>2786266
>>2786268
>single-phase
180 degrees is NOT a phase. This difference is crucial. Phase is what allows a motor to start. A split phase system cannot start a motor, you would need a shaded pole or a starter motor (with its own shaded pole). "Two phase" systems still exist or have existed but are mostly obsolete now. The phase in that case is 90°, not 120° nor 180°.

Shut the fuck up, nerd.

>>2786239
>230 volts, if you are at 250 you are 3 volts from nominal failure

Why do people who know nothing always talk the most?

It's 230 volts -6%, +10%, meaning anything between 216 and 253 is within range.

>>2786268
>it is a single phase that is center tapped with a grounded conductor
Finally. Someone who knows what they're talking about.

OP, why don't you just return the cable to where you purchased it and buy the correct cable for your project? (3 conductor)

>>2786239
I'm replying to OP in the same post and you still assume I'm OP, you don't know the nominal voltage ranges, and you still go out of your way to try to lecture people and call them retards because
>I'm le certified electrician big boy, if I think it's true then it's true
The standard range that most of the world uses is 220 to 240v, there's no fucking way that universal "smart" devices are designed with 3% tolerance, at most extremely sensitive devices like UPS might allow you to set thresholds that low. I said 250V because nobody cares you fucking nerd.

>>2786252
*120v

>>2786190
Whatever the fuck but
>2) Double both live and neutral with no earth
Do not remove PE, that's absolutely retarded.

>>2786236
Muttmerica is 300 million weak. The majority of the world indeed has 220-240v single phase 400v 3 phase.

>>2786260
>and do you actually have shit that runs on it?
Every single electric cooktop with 4 burners
2 burner cuck models or 2 electric + 2 gas burner use a single phase 230V. Washing machines, dryers, most ACs and water heaters run off single phase too, though bigboy heat pumps and central water heaters over 200L with heating elements over 3kW need 3 phase.
Standard breaker for euro single phase outlet is 16A so we can draw 3.6kW from them. Lighting circuits use thinner wire those get 10A which is hilariously more than a lot of American outlets get but I guess it's also practical to be able to wire them all into each other, it's not standard here.
>>2787056
It's really just 240v you dumbfuck selfdoxxing mutt. The wires to run a water heater or stove off 120 would need to be absurdly thick because it'd be like 60A.

>>2786201
>In principle double neutral, single live earth would be beneficial
what principle is that?

personally i would connect to earth if not in use just to give it somewhere to be so its not floating around inside wherever it is.

>>2787166
USA has 240 wires where we need it, like the dryer, water heater, stove/oven, well pump.

>>2787169
>those get 10A which is hilariously more than a lot of American outlets get
15 amp breaker for most outlet circuits

>>2788572
Stoves get 400V 3 phase connections, big water heaters get it, dryers don't pull 3600W so they can get single phase.
>>2788573
Oh wow a whole 1800W! Fucking hell I thought it'd be more than that.
230*10=2300
The usual outlet is 16A (2.5mm wires)

my 3 phase 18 kW central heating boiler laughs at american scum

>>2786270
>Single-leg, single-phase, 250V leg to ground.
This.
OP is in Europe. Hence the "I have 200m". And Canada doesn't have electricity yet.

>>2789437
My 1 phase 36kw heater laughs at yours as it dims the lights on start up

It's split-phase.

Numerous others have already slapped your face for such a mistake. I have, at one brain farty day, used the term 2-phase, and got visited by heath ledger's Joker, who thought I was now his best buddy.

>>2786288

Ouch

>>2789312
> Stoves get 400V 3 phase connections, big water heaters get it
> run 3 phase to the house just for the stove

We just physically connect 2 16A breakers together and then run 5x2.5mm for a whopping 7.5kW total

>>2789722
>> run 3 phase to the house just for the stove
Yes. It's been done since the 70s here.
>physically connect 2 16A breakers together
Sounds jank can't you just put one 32A?
>and then run 5x2.5mm
That is the standard three phase outlet cable...
>for a whopping 7.5kW total
So jack shit compared to a true three phase outlet.

>>2786248
But he's completely right. A 4 wire cable like OP's pic has the colors of L1+L2+L3+PEN. Not sure where you'd use one that thin in a domestic setting really. Outbuildings should be on TT earthing anyway (N and the PE is just a rod at the building which is never tied to N).
>>2789437
>>2789636
Both of those would melt my house's cables, god damn.
How small is your house that you can heat it with 18kW anyway?

>>2786190
You know, the extra wire won't do shit by just being there while being not connected to anything.

you may leave the fourth cable to do nothing and use the 3 as live neutral and ground, but make sure that the unused cable end is properly insulated and kept away from the rest of 3

You may double the amp carrying capacity of the whole cable by Doubling both live and neutral with no earth but by doing that, you need to be super careful with color code

Best is to just double the ground, that way any nick/damage in the cable is even more likely to trigger a GFCI

But 200m? if it's that long, contractors will sell their soul to get it on discount so make your life simpler by switching to 3 core
