      One of worlds longest running experiments is when an european tourist visited america and tried to boil water using a kettle and a travel adapter.

      The paper published on the experiment noted that water finally reached temperatures of 63c in 2017.

          Steam irons heat faster too, you know, just in case you need to iron your fancy shirt in a hurry before you leave, not that that would ever happen to me or anything…

          Btw do you have a big solar array or what is the inverter for?

            Yea, big steamer vs iron fan here. This will be for a van. A while back we aquired a mini van and through the magic of DIY it now has no back seats, a couch+bed, fold up kitchen and running water. We are very outdoorsy and like cheap travel, so we are doing some planning for potential next/future stage of life in something that could replace structural living 😉

                No more than a pot on induction. Or for that matter, no more than with propane, or friction, or pressure, or with a mini-sun. Takes the same amount of energy regardless hah.

                Speaking of which, this is a pretty cool tool: https://www.omnicalculator.com/physics/water-heating

                So for 1 liter in my case, a 2K watt inverter woth 80% efficiency across the system would take under 4 minutes to boil.

                  That’s 25AH of capacity on a 12v system though, so quarter of the capacity of a 100ah battery, if I’ve done my math right.

    The Type I plug was developed by the US government but blocked in Congress during the FDR administration by the Republicans and southern Democrats on the basis that it was a change from the multiple different outlets being used at the time. The 3 core plug didn’t become standard until 1965.

    Regardless of where you are, can we all agree that no one’s really perfected the electrical outlet yet?

    NA plugs make contact without being fully seated, and can leave their live and neutral pins exposed. Worn outlets just let plugs fall out of them (I have 3 or so outlets in my apartment that are borderline unusable because of this).

    British plugs are bulky and turn into caltrops when dropped on the floor.

    European plugs have the same problem. And you only get like, one outlet per receptacle? Guess you’re shit out of luck if you wanna plug anything else in the same spot.

    Most of the rest of the world just copied Europe or the UK.

    I like Denmark’s plug though. Cute lil smiley face.

        So do we. But we don’t need as many of them, usually just for areas with a lot of electronics like entertainment centers or computer desks.

        US electric code requires an outlet like every 6-8 feet (~2m) along a wall so you shouldn’t need to string extension cords everywhere. For the most part, it works pretty well. I have 5 outlets alone in my 12x12ft (~3.6x3.6m) bedroom.

          Compared to the US, EU extension cords are actually reliable and not death traps. It’s not a big deal if you need one.

          But as I said in another comment, one outlet per receptacle is not the standard, at least not here. We have two.

      The standard amount of outlets per receptacle here (Sweden) is two. Maybe in very old houses it would be only one, but that’s rare. If you run into that, there are splitters that make one into two, you don’t need to have an extender to split it.

      Does NA not have insulated pins? Where a half inch of so of the pin nearest the plug head is insulated so when plugging in the exposed part of the pin is inside the hole before the pin makes contact with live power?

        It does not. Some devices may have that on their plugs, but it’s certainly not standard.

        One night when I was 14, I tried to plug in my phone charger beside my bed in the dark and was accidentally touching one of the pins when it made contact.

        Fortunately, I wasn’t completing the circuit and I was electrically isolated laying on my bed, so I didn’t actually get shocked. But I did feel a buzz in my finger like you get from those prank toys that shock the victim. That’s a sensation I will never forget.

        Not defending our plugs at all.

        It’s a right of passage for a kid to learn what a 120 volt shock feels like if they’re careless in unplugging something. One pin is just an unforgettable sensation, while both will knock you down. The real mystery is why code requires the outlets installed upside down. Technology Connections did at least one video on the differences of outlets in the world, and his point was that if the ground pin was above the other two, something falling on a partially exposed plug would rest on the harmless ground and not what it can do, short out the two live pins. But then we wouldn’t get the cute faces, so…

          Code doesn’t specify the orientation of a standard duplex 15 or 20 amp receptacle. Personally, I’m of the position that they should be ground pin up, for exactly the situation you specified. But, since there isn’t a code mandate, residential customers and the occasional commercial customer will make you flip them because “they look weird upside down” (ground up). I think a lot of this comes from the old K&T days when it was standard practice to place the hot terminal on the right and neutral of the left, assumably because most people are right handed, and they added the ground on the bottom to make the face as it was more aesthetically pleasing. Granted, this last bit is all pure speculation.

          The fact of the matter is that since I can’t draw a code reference to ground up, I install residential ground down. On commercial jobs I’ll ask the client directly and explain the hazard, since they’re more liability minded, and they’ll typically go ground up except in reception areas and the like. People are funny.

            Funnily enough this did happen to me. It was a cat toy that was mostly just a long metal wire. I found it on the ground in 2 pieces and couldn’t figure out how that happened…until I saw the marks around the outlet. Definitely feel lucky that nothing caught fire and no cats were harmed. Not that I’m going to flip all my outlets or anything, but proof it can happen!

        Most connectors I have use partially insulated live/neutral. Ground is optional and completely uninsulated where it’s present for safety.
        Also, recessed receptacles hide the most dangerous parts.

        The on/off switch always struck me as odd. Like, in a recessed plug such as this where the male prongs have a bit of insulation to them, are they really that worried about a tiny arc that might occur when someone forgets to turn off the device? Like it would make more sense to have a limit switch built into the socket that activates on insertion and deactivates on removal. And even then, with our caveman sockets in the US, a small arc isn’t the end of the world, you just know not to have your fingers near the shiny bits.

          Not safely with 240V. The smaller US plugs can only take 120V. The benifit of the larger plugs is they are more rigit, don’t come out easily and provide proper insulation. Thin EU plugs exist, but aren’t sufficient for heavy users. Lamps and phone chargers have the narrow plugs because they don’t pull as much power but a heavy device needs a bigger safer plug. Like a microwave, a PC or a table saw.

          Never had that issue with euro plugs. Downside of UK plugs is there’s only one orientation you can plug them in. And those plugs are really chunky. I have many synths, with many power plugs, I wouldn’t know how to plug them all in at the same time. I would need maaaany power strips. Also, the flat wall plugs in the UK can wear out and not hold that well. I’ve been in old B&B’s where plugs would just fall out. Eu plugs are sunken so always hold properly.

        I think the Swiss have the best Europlug-based system. Their three-conductor plugs have the same footprint as basic Europlugs, which makes for very dense plug arrangements. Unlike e.g. the German Schuko plug they only fit in one orientation so you get no polarity issues.

        It’s pretty neat.

            That’s quite how AC outlets work. Line and neutral can intentionally have different potentials relative to ground depending on how the house’s electrical system is designed. This can become relevant in certain situations like very simple devices (think “lamp socket with a power plug”).

            A plug that can’t be inverted makes this a non-issue.

          polarity issues

          Not an issue, you can swap line and neutral freely. It becomes an issue if you want to use three phases and a three phase motor (because the order of phases is important) but that is covered by other sockets. Plain old Schuko is one phase, LNG.
          EDIT: thought about it some more, yeah, devices with switches on L may be pose a shock risk in some cases if you swap.

      For most things people bring on vacation it wouldn’t be a problem since chargers and power supplies can run on multiple voltages. It’s for things like hairdryers where you need converter. Since they are calibrated for a specific voltage to create heat. Though you could probably run them at half settings on the double voltage.

      Oh this gets stranger.

      It’s usually 120v, but I’m not going to split hairs over 10v.

      So, 120v is not a voltage that is delivered from the grid… Technically speaking. Each home is given one circuit of 240v, which is usually part of one leg of a three phase, coming off of the Transformers… 120v is there because they center-tap the transformer. This halves the voltage by consequence. Inside the house the circuits are generally laid out to try to balance the load between each half of the 240v phase.

      The idea is that two 120v loads, put in series, will total 240v. So power will ideally go from L1 to a 120v load, to “neutral”, then over to another 120v load, then finally back on L2.

      More or Less.

      120v is basically just half of what you should be loading the system with.

      The center tap neutral from the transformer is to collect any load imbalance between L1 and L2 to allow for the two “sides” of the phase to be out of balance and still work.

      The US “plug” ( aka receptacle ) is a NEMA 5-15R, or NEMA 5-20R (for 20A); these are designed for 120v operation using the half phase described above. Of course, you can mis-wire it and make all kinds of dangerous abominations if you so choose. There is, however, a less known NEMA 6-15R and NEMA 6-20R that is basically the same, but for 240v operation, replacing the neutral wire with L2 instead (and 15/20A respectively).

      So it is entirely possible to have 240v outlets in a North American home, while still being compliant with code.

      It’s actually really fascinating information when your dig into it.

          I’m not an EE. I apologize if I gave that impression. I just have an obsession with understanding anything I use on a regular basis, whether computers, smartphones, electricity, vehicles… Anything that does stuff, and I use it, I want to know how it does the thing that it does.

          I’m weird like that.

          I learned a lot from “Electrician U” on YouTube, along with a few others. Maybe worth a look. The scientific/physics side of things was more from watching other YouTubers (as to why it behaves the way it does), along with a fundamental knowledge that I learned from doing amateur radio stuff. Working in IT and having to deal with the power requirements of systems and making sure that we won’t blow a breaker under load… That helped motivate me to learn.

          It all came to a head when we were deploying a network and server for a business that was still in construction of the facility. The electrician was going to run a temp line for our stuff so we could set up and be ready for opening day, and he asked how many amps we needed… I did a bit of a deep dive to figure out an answer for him, and I’ve been learning more and more since then.

            Cool. Thanks for the direction. I’m curious about electrical stuff, and I’d like to be able to do some things around my house. There’s some DIY stuff online, too, involving building projects from old parts of appliances that interest me, but I realized quickly that I’d need some very good knowledge about electrical work to stay safe. It’s unlikely I’ll actually pursue the latter, but I’d like to at least know the how and why of my home wiring.

              My recommendation is to maybe get some electrical safe tools, possibly some gloves that insulate against shocks, but definitely a good non-contact voltage detector, or NCV.

              Check the circuit with your NCV before turning off the power, before working on the things on the circuit, and after turning on the power when you’re done (before you switch anything on). It helps keep you and your house from halting or catching fire.

              … And always connect ground wires first.

              Good luck.

      Houses in the US generally have 220v too but not at ordinary wall outlets

      There’s a technology connections video on it if you’re interested in the specifics

        When I was 17 my father brought back a stereo from Japan. I was too eager to use it and plugged that directly to 220. It worked for a glorious 2 minutes. We got it working again after we replaced the transformer. Still have it and it still works fine to this day. Learned a lesson too!

      3 phase? Think about that for a minute. That’s going to be one fancy ass convertor.

      A simple transformer can convert 120 to 240 easily, but 3 phase is a whole nother thing, you know. Or maybe you don’t know.

        No need for me to think about it. I own such a converter. Had to get it to power a chinese-made 02 generator that did not have a switch to go to single 110

    Thailand has really cool plugs. they’re shaped so they can fit European or American outlets, quite often. I rarely needed an adapter when I was there

        No, voltage adapters are built into basically every electronic device now so it doesn’t matter which you plug into

          Yes for electronic devices that expect low voltage DC and have a converter, like laptops, phone chargers, etc.

          But don’t try and take a 120V hairdryer on holiday and plug it in because it will certainly blow up.

            You definitely need to distinguish “electrical” devices from “electronic” devices but a safer approach is to read the plug.

            • A power supply (ex. Phone charger) will be stamped with a voltage range and power draw, which probably includes everywhere but you can match it against the electrical service where you are. You may need a plug adapter but a simple mechanical adapter is sufficient.
            • an electrical appliance (ex. Hair dryer) plug is probably not stamped with electrical requirements so the safe approach is to only use it in the intended country

    I mean makes sense, there is a big Chunk of population in the USA who don’t have the means and opportunity to travel abroad and get used to the other electrical outlets in other countries.

    Hell I think 30% of the adults in there haven’t ever been abroad once on their lifetime.

    Understandably, it’s going to baffle more than one person who gets shared those travel experiences from traveling acquaintances

        For power In the U.S. I have to use USB-A, USB-C, Lightning, cigarette lighter adapter, 110 plug without ground, 110 with ground, 220 - 3 types of connectors on those just for dryers, adapters still for mini USB, micro USB, and that’s all before we start to get obscure. Universal lightbulb plugs? Nah everyone had to fuck that up as well.

      US used to be like that too. When polarized plugs first became a thing, they wouldn’t fit into older non-polarized outlets. It took decades for all those to be replaced and I’m sure they’re still out there. Somewhere

        Still I have one (1) in a stairwell in my house. So far I’ve left it alone, partially because it also has a stupid piece of stair molding blocking part of its cover plate but mostly because I have never in all my years found any reason to plug anything in there.

        Somebody probably originally intended it to be for a vacuum cleaner or something, but even the corded ones I’ve owned have had cords more than long enough to reach both ends of the stairs from a selection of other nearby, non-stupid outlets.

    I know it’s difficult to tell online, but I read that as a joke post. Not serious. But it’s better for others to make fun of others for being clueless I guess.

      Yeah. It always strikes me as bizarre how many people online see something that would only be satire in a sane world and completely assume it’s serious. They have no doubts. Never occurred to them it might be a joke…

          I feel like it should be more like “Poe’s sometimes true thing” because satire does indeed still exist. People making assumptions is the issue.

            People making assumptions is the issue.

            There’s assumptions involved in detecting satire from just text as well. You would just have a Reverse Poe’s law where “any extreme views can be mistaken by some readers for satire of those views without clear indicator of the author’s intent”.

            Normally when people say or type things we (justifiably) assume that to be what they mean, which is why satire works much better when spoken because intonation can make the satire explicit without changing the words or saying it out loud.

              I never said anyone should assume something is satire. It’s possible to just not know something and not make a judgement.

                Never assumed you did :), but yes, as little assumptions is the best. But as you can already tell, it’s hard to communicate when you take no assumptions when people make explicit statements crafted to dispel assumptions, that are entirely plausible for a hypothetical real person to have.

                In fact, your original statement of “They have no doubts. Never occurred to them it might be a joke…”, is in itself a pretty big assumption. Unless, of course. I assume that statement to be a hyperbole, or even satire. But if we want to have fun talking about a shitpost we do kind of have to decide on an assumptive position on the meme that can’t talk back.

                  So yes, you have to make some assumptions. But to me it’s pretty clear that if someone is expressing anger at a possible joke that would be messed up if not a joke, they probably aren’t trolling/joking themselves. And then even if some people were, when you see people doing it en masse, I think it’s a safer assumption to assume no one gets the satire than it is for them to see a single random thing online and then get mad about what they think it means, when there are multiple possible interpretations
