>110v
Why do ameritards use such a low voltage?
>>
Like most other weird shit related to electricity, it's because Edison was an asshole.
At this point it doesn't really matter, it's just a matter of being hidebound.
>>
Edison was a DC guy. Tesla is responsible for pretty much all the AC stuff we have. and 120V is just the right voltage to tickle your prostate using a long carbon rod.
>>
>>1216997
Americans literally microwave water because the voltage is too low for the kettle, converting to higher voltage can't be that hard
>>
>>1216991
For the same reason Europe uses 50 Hz. Because some shithead thought it was a better/cheaper idea at the time and it became the standard so now it's too late to change it.
>>
>>1216991
because 230v is master race metric electric - 110 remains a good imperial number for the last remaining imp race (and contrary claims that Muricas equally retarded cousins Myanmar and Liberia, or whoever the fuck, are also still in the dark ages of international measurement standards, are actually urban myth). As example, the famously progressive regime of North Korea currently has 230v, nuclear weapons, the metric system and a tinpot dictator. Murica only manages two of these. US also had a really shit standard for TV broadcast, despite that being their main form of leisure, free time and exercise (when remote lost) activity. The moral, never let an American declare 'a standard' - they are fuck useless at it.

You're a fucktard.


It changes from America to Canada too. Industrial operating voltage in Americuck is 480, Canadafags 575.

Everyones different. Kinda glad it went this way or we'd have another fucking cartel on our hands when it comes to 110 and up.

Also I have no fucking idea why this waste of a troll killed yet another thread for this faggotry. This belongs in /g as its a tech question.

and for applications where you use 240V we go with three phase at 16amps

burgerfags btfo'd once again
>>
>>1217007
And where we muricans use the imperial system it's because base 16 is master race, and base 12 ain't too shabby either. Base 10 only seems better to those with a low iq because they need to count fingers to do math. Tell me, what's a 3rd of a meter equal? A third of a foot is simply 4 inches. How about a 6th of a meter? Again, pretty simple to represent in our master race system

Low voltage is due to legacy equipment. We had electricity while EUrofags were still using gaslight.

It works well enough which is all that functionally matters. Plugs bother autspergers, but autspergers are a fine argument for their own elimination by eugenics.

There are sometimes code restrictions, such as that grounded and ungrounded outlets can't be mixed on a branch circuit.
Also, in some older construction, aluminium wiring was used, which corrodes when under load and in contact with copper, requiring specialized type CO-ALR fixtures or pigtails to avoid setting the building on fire.

Oh you mean the initial inductive kick. Yep. You're right it'll quadruple. Kekekekeke.

But then it don't make it much different from Americuck tools to euro fag tools. From what I can tell the punch on the wrist feels the same. Maybe the American tool have a greater moment of inertia cause of the heavier windings, and the euro tool has more kick with a lighter winding. I just remember using either one and they felt just the same.

There is no law that says you have to upgrade a 2 prong outlet to have a ground. There is nothing wrong with a two outlet, to begin with, as long as you are using 2 prong cords. Plugging a two prong cord into a three prong outlet does absolutely nothing more than plugging it into a two prong outlet. Personally, I would rather have a GFCI outlet than just a standard outlet with a ground. Grounds are all well and good and should be present in new construction but there is better technology out there.

We regularly have brownout warnings because we haven't built any power plants since the early 90s.

>Power is power no matter the voltage.
A power tool is usually a few wires connecting to a load with some finite, near constant, nonzero impedance, Z. If you've ever opened up an angle grinder, its just a universal motor in series with a switch across the mains, no smart voltage regulating or anything of that matter; it would just waste more power and cost more to build. The current, I, going through that load is proportional to the voltage, V, and is precisely equal to V/Z. The power, P, going through that load is equal to V*I. From this we can get P=V^2/Z. The near constant impedance doesn't change significantly when you plug the grinder into a 240V wall socket (the only changes are due to the different frequency and/or different motor speed), and since the voltage did change, you're now burning 4 times the power, and therefore 4 times the heat. If your grinder's got a high enough power rating, the windings will take a shit on your grinder, melt or burn their insulation, short together, draw even more current and hence more power, and ruin your grinder before your breaker trips. But seriously, go ahead and try it if you don't believe us.

I would love to think that /diy/ has this never ending discussion because of trolling, but some part of me realizes that /diy/ is chock full of autists who know just enough technical information to convince themselves that they are technically literate, while in reality they don't understand anything.

Arguing about 110 vs 240 or whatever makes sense, but as the level headed ones have said, decisions were made and are hard to undo. But the whole "what happens when I take a 110 volt device and power it with 240" is pure nonsense. Why not plug it into the 240000 volt transmission line? You don't because it would be retarded and you would also be in a viral video. But the same stupidity applies to the 110 vs 240 on one particular design.

/diy/ will always be like this, and that's part of the appeal. You can toy with morons when you are bored, and they never stop entertaining you.

and thanks to the superior SI system it is pretty simple to prove your faggotry
a cup of tea requires about 200ml of water being heated from 20°C to 100°C
specific heat capacity of water is 4.2kJ/kgK
4.2kJ/kgK*0.2kg*80K=67.2kJ
67.2kJ/10s=6.7kW
your ten second kettle would need perfect efficiency and 6.7kW of electric power
so unless it runs on three phase that's not gonna happen
on a normal 16A outlet you can get up to 3.6kW which means just under 20 seconds
or more realistically 30 seconds considering that you not only need to heat up your water but the kettle as well
still faster than a microwave though
now I'd love to see a burgerbro do the same calculation in imperial units
>>
>>1217617
I've got 240VAC mains where I live in NZ and you can pull 20A through a socket (though it isn't recommended) without tripping a breaker, giving 4.8kW. But since the sockets are only officially rated at 10A, it's certainly illegal to try to sell a device that draws more. But remember, a heat pump is more efficient than a strictly resistive heater; a heat pump's maximum theoretical efficiency/COP is equal to T_hot/(T_hot - T_cold). For him to get 6.7kW out of a 4.8kW outlet, a COP of 1.4 is needed. Plugging in the numbers for temperature, maximum COP = 373.15/80 = 4.664, so it actually is theoretically possible with a minimum power input of 1.436kW. Not that I think he has a kettle with a compressor inside or anything. But its pleasing to see someone else on this board with physics on his brain and SI in his heart.

If you're calling bullshit on the potential "over-unity efficiency" of a heat pump, it's only a google away.

>>
>>1217641
>heat pump
that would be a possibility
but I didn't mention it because a heat pump would add so much thermal mass that it would most likely perform even worse than a resistor in time constrained applications
another option would be to fill your kettle with hot water from your tap which would save you about 30K in delta T, but again real world taps take at least 5 seconds to give you actually hot water, compromising your gains

Ovens and stoves usually are connected with a three phase cable but they are in reality phase to neutral. It's just convincing to have the load distributed over several phases instead of running it on one. But if you have a flat with just a single phase panel then it's just wired in one phase as it uses phase to neutral voltage...

My small angle grinderd are 900W. I bet a 900w compressor can't run a pneumatic angle grinder with equal oomph. My big angle grinder is 2,2kW. I bet my small compressor of 2,2kW can't run a big angle grinder with the same oomph as my big angle grinder!

Just check out how much heat a compressor generates. That is wasted heat. Compressing gasses heat them up and that heat needs to go. This is because of physics and can't be avoided. I still claim that pneumatic tools both rock (if you have the air supply) and are unnecessary inefficient powerwise.

Big compressors definitely use a lot of power but that don't need to run that long depending on your tank size and runtime. A 80 gallon compressor will barely need to run for most tools. You also get way more power at the tool which is more efficient.

And now the correct answer, so that we can close the thread:
The common arc lamp used back then has a forward voltage of 55V. The murricans decided to put two of them in series, we yurops used 4 in series. later most of europe increased the voltage from 220V to 230V.

ok, you're right.
Edisons "jumbo" generator (DC) produced 220V - needet for 4 arc lamps. in this 3-wire net the middle wire is set as neutral, so the other wires L1 and L2 are -110V and +110V.

In Europe we used one wire for neutral and the other wire for 220V - thats all, i guess. meantime the DC generators have been replaced by AC, but they kept the voltages. Also, US- Generators and European Generators are 3~Phases, so you have 3 times +/-110V respectively 220V.

Murrikans can only power a kettle with 110VAC at 16A max = 1760W. This is slower than just using the gas stove and a pan of water.

UK, 240VAC at 13A = 3120W and enough to boil a pint of water in no time at all.

Induction is as good, if you can pump the power into to it. Gas stoves are so good because the element itself has no thermal mass/heat capacity, letting the pot change temperature as quickly as its own heat capacity will allow it, and an induction hob does the same thing by powering the pot through EM. While I'm not sure if you can get the same raw heat output out of a standard induction stovetop, you certainly could build one that could. Of course you do need a ferromagnetic (maybe ferrimagnetic too?) pot, even copper-plated pots don't work.

I remember the last and only time we used the "boost" button on the induction stovetop at my parents' house, we warped the bottom of a stainless pan b a good cm or so. In comparison, my flat's shitty resistive iron hob has far too much heat capacity to be convenient.

I don't follow this, unless it's that old autistic crap being spewed by people who don't understand electric power.

If the kettle is using 3kw it is using 3kw no matter whether you are operating it off of 1 volt or 10000 volts. The heating element will be sized accordingly.

If you take a particular device and double the voltage and it is a simple device it will consume 4x the power because voltage and amperage will both double.

I'm not even going to address the coper losses and the cord bullshit.

For the same copper losses in the cord you get twice the power in the device with double the voltage.

I think that will change once induction hubs with good closed loop temperature control (instead of power control, which is what we have now). The consistency of absolute temperature control will be hard to resist.

It is bullshit (or OP has the wrong details), as cheap hair dryers typically use DC motors with rectifiers, which would be unaffected by frequency. They'll even run just fine on DC.

The expensive hair dryers use BLDC motors, which are driven from switched DC produced by a rectifier (and probably SMPS). Again, even fine on DC.

>If the kettle is using 3kw it is using 3kw no matter whether you are operating it off of 1 volt or 10000 volts.
If the kettle is on 1V, that 3KW requires 3000 amps, with the corresponding resistive losses in the supply wiring. If the kettle is on 10000V, it only needs .3A, which would produce one ten thousandth of the resistive losses in the supply wiring as the 1V kettle. Amperage, not voltage or power, is what matters for how hot a given conductor gets, and therefore how much energy it dissipates as waste heat.

Or to put it in more realistic terms, a 1200W kettle on 120V would require a 10A supply, which requires a particular gauge of wiring depending on the situation and code involved. Let's say it's 14ga. A 2400W kettle on 240V would also require 10A, which corresponds to same wiring requirements as the first kettle. The 14ga wire would experience the same power losses while conducting those ten amps in both cases, but the 240V circuit is transporting twice the power as the 120V circuit.

No. Chefs like being able to see the fire. They are artists and don't want a bunch of controlled induction coils beeping at them when the computer thinks the food is done. I want to feel more control than that. Flame is also great because you can look at a flame anywhere and know how hot it is

Yet there's sous vide, there's molecular gastronomy. Also the artistry is in creating the dish, the line is expected to reproduce the chef's work with consistency. They make reproductions, not art. Temperature control which doesn't rely on the vagueries of human's assessment of proxies will help with consistency.

I think the line will appreciate less of the heat going into the air far more than the loss of the pretty flames.

the 'instant boil' things (as per >>1218247) actually are 3kw - long as max 13A (@230v..)?, you good. They kettle makers, not Chinese Amplifier manufacturers - aint gonna rate them higher than actual usage.

used to have(s) pic related - 2800W (@230v..), annoying pish, would last about 6 months before crapping out, usually the pump. Alright for (instant) coffee but not hot enough for tea, nowhere near boiling. Theoretically, an 'instant boil' design should save energy (only heating what you actually pour via snake heating element)-practice tho, you cant reach actual boiling with this method, tastes mildly metallic odd (nowhere near as fucking odd as microwaved tho) and they fuckup , lots, as noted. Newer models as per >>1218247 pic maybe better, but Burgers ain't missing much on the 3kw kettle front otherwise with any of these, IME.

Induction has plenty of power, but it loses all of it the moment you lift or tilt the pan. So at the moment you lose something while gaining nothing of importance (induction begets you a cooler and easier to clean kitchen, but who cares about making life better for the line?).

Induction will actually have to offer an important improvement to overcome that loss and inertia. Accurate temperature control would do it IMO.
>>
>>1218339

The Breville one works differently. You hear water loudly coming to a boil and then it dispenses 250 ml in one gush.

I suspect it has two chambers, with the water travelling to the upper chamber driven by steam before it's dispensed. Similar to how a drip coffee maker works. That way it would just need two solenoids, no pump to break down.

Almost like their budgets have been cut, huh? Adjusted for inflation, their budget peaked in 1966 when it was 4.41% of the Federal budget. By 1971 it was less than half of what it was in '66, down to 1.61% of the federal budget. They saw a little bump in the budget during the Bush Sr. and Clinton years but it dipped back down after that. It is currently sitting at 0.47% of the federal budget. It hasn't popped above 1% since 1993.

>The consistency of absolute temperature control will be hard to resist.
Agreed. But you could technically put a thermocouple in a pan over a gas element and control the gas flow with the feedback, but be it induction or gas, you'll need some fairly smart sensor to understand or at least estimate the heat capacity of each pot you use. Theoretically you could measure the temperature of an induction hob by measuring the resistance of the pot, but again the particular pot would have to be calibrated. Ideally, you'd be able set the pot to put in the energy to boil water so many mL/min, which is pretty easy as long as you're radiating an insignificant amount of the heat away and have a good gauge of what efficiency you've got.

Also, not using pic related.

But if you're using the same power cable with the same resistive losses, then the current you pull to maintain the same useable power output over different voltages will change the amount of power your cable loses. If you tried to use a normal 110V power cable somewhere that uses 10V mains, you're going to have large resistive losses within your wiring.

No, a universal motor is a DC motor with field windings in it, while an AC motor with commutators in it brings to mind an induction motor with slip-rings. The notion that a DC motor/generator was made by putting commutators in an AC motor/generator probably refers instead to a synchronous motor/generator (probably induction) with commutators within to turn the AC output into a form of DC.

We really should move everything to 240v, most electronics comes with 120/240v power supply already. AC/major appliance are 240v too, the only thing left on 120v are lights, fridge, washer.

Barring unusual circumstances, your home is already getting 220V single phase AC from the transformer to the panel.

That is not the root of the problem. The problem is, that burgers only have single phase connections. I could not for the life of me imagine living without a three phase socket in a house (in a flat, fine, I guess). How do you even build a house without a three phase connection? How do you run a proper saw, or cement mixer, or any stationary tools without three phases? It is clear, that the reasons ameritards have only single phase connections is because the Jews don't want them to be independent and able to actually do anything at home, therefore forcing them to buy stuff.
>>
>>1218943
There is three phase in the U.S., it's just not to every home, because not everyone needs it.

Most homeowners would not know what to do with a good three phase hookup anyhow.

Also- small concrete/mortar mixers here tend to be gasoline driven, not electric, and the larger 110 volt saws do well enough for all but the largest DIY projects. Beyond that, you either already have three phase, or you're using phase converters.

It's a non-issue for most people.

>>1218943
Brushless DC motors are better than 3-phase AC motors anon.

I think universal/DC motors and induction motors have completely different torque curves. Different uses for each.

>>1218943
On a construction site, almost everything is either battery operated, pneumatic, or uses fuel.

Once the house is built, you will generally have access to at least 220v power. That is more than enough to run even a large cabinet saw or wood lathe. The only thing I can think of that would need more would be a large, old school metal lathe. Even with the only 110v, you can still get about 1.5 HP out of a motor. Plenty for a smaller table saw, a large drill press, or most any other home shop tool.

That is what we are talking about, right? It isn't uncommon for even small businesses our where I live to have 3-phase and 440v power available to them. Stuff like an auto mechanics or furniture shop.
>>
>>1218962

As long as we don't distribute DC, three phase is still nice for a high power DC motor. Simply so you can get a decent power factor without tons of capacitance.

That doesn't mean jack shit when you have a 20 amp service. If you tried to run an industrial 3 phase anything you'd pop the main breaker.

tldr 3 phase in your shitty flat is different than industrial 3 phase used in North America.

A lot of farms and acreages do have 3 phase power service in North America.
>>
>>1218134
You licked a lot of exposed wires didn't you. Edison and Tesla were both trying to win contracts for supplying power. Edison tried to scare Americans into using DC by electrocuting an elephant with AC, and invented the electric chair. While Tesla won out by supplying AC power at cheaper prices. It wasn't about inventing, it was about business.

Electricity 0.2 - Edison was a dipshit that pushed for DC Electricity but it could barely cover a city.

Electricity 1.0 - Nikola Tesla invented AC and it worked! We were beta testing while you shitlords were starting a bunch of wars that we had to come finish for you. You're welcome Eurofags.

Now, to answer your dumb-ass question that you could have googled pretty easily.. We actually do push 240v residential service. But it's split into two 120v circuits. Why? Blame Edison. His light bulbs worked best on 110v (which only got upgraded in the 50's to 120). Why keep 120v around? It's safer and most appliances don't need more.

Our bigger appliances such as Washer, Dryer, Water Heaters, Air Conditioners, etc.. actually use 240v by taking a hot from each circuit. The result is 240v.

Also, we could upgrade everything with little to no infrastructure change and a few changes in houses and it'd be slightly better and still safer than anything in a Eurofag's house.

You're Welcome.

Well excuuuse me Bill Nye the science guy. Ahh Germany, where you need to arithmetic to wire a lightbulb.

That's an older panel, Newer ones have 40 spaces which takes a pretty big house to fill. If you ran out of spaces you would add a sub panel if your incoming service permits it. Newer really big (3500sqft+) houses have a 400 amp service and two breaker panels.

The main breaker is attached either above or below the breakers. The electric meter sits outside most the time.

It doesn't need to look pretty. Keep 'er simple. That's the American way.

>third world tier
Oh I don't know. You people still use fuses and put your washer and dryers in the kitchen. That's weird.

>wood frame construction
oh boy

>still use fuses
they are used because they'll blow slower than the RCD/breaker they connect to upstairs

>washer and dryers in the kitchen
how'd you come up with that? they are obviously in the basement

btw I'm still waiting for a pic of your panel and not just some google images

I've seen a lot of "flats" with the W/D in the kitchen.

Why do you want to see my panel? It's a newer 200A cutler hammer that's about half full with some dirty old 70's wiring. There's millions that are basically identical. Had to upgrade it and the lines coming in a couple years ago because most insurance places won't touch anything under 100amps.

only city people in small and old apartments do that because they have no other place to put them
newer buildings will have a recessed space for them in the bathroom if there's no basement

>Had to upgrade it and the lines coming in a couple years ago because most insurance places won't touch anything under 100amps.
seems like you are the one with a 24kW connection after all
>>
>>1220237
Nope 200 amps @ 240v. The new lines coming and main breaker are good for 200a. Older houses which are becoming more and more rare have a 100a or less panel but all newer houses and reno's are 200a or 400a.

the Edison lab was primarily a patent trolling machine. just like IBM, they patented the most obvious, most useless of things, so they could use them as weapons against their competitors. ultimately, both ended up in trouble coz most of the innovation was phoney. (IBM just posted its 21-st consecutive money-losing quarter)

Oh really? Well it's not like he invented nothing useful, but I guess 2300 useful and innovative inventions is going a bit far.

you can't get more than 43.5 kW with 63 A 3~ no matter how you wire it.
>>
>>1220498
yes you can
since the three phases are shifted by 120° you can connect your appliances phase to phase (full lines in graph) instead of phase to neutral (dotted lines in graph)
this gives you an effective voltage of 230V * sqrt3 = 400V
and 400V at 63 Amps give you a power output of 75kW

for every linear delta circuit there's a electrically identical star circuit and vice versa. a delta circuit being able to draw more than a star circuit directly contradicts this.

There are maps. That show where the lines go.
>>
>>1219792
Actually, it's split single phase, generally closer 120 and 240.
