UK are safest, EU are both practical and almost as safe (as it supports a variety of plugs, both with and without grounding), and US is complete and utter garbage built for garbage voltage. Plus, the US one looks scared.
Plus, the US one looks scared.
Even our outlets are terrified of how bad the plug design is.
Try going to Japan. They took the US design, but most outlets there don't have the grounding plug (in hotels it was practically non-existent). My travel adapter didn't even work xP
It's goes far beyond grounding, half of Japan use 50hz and half use 60hz.
UK are safest
Until you step on a plug...
You thought Lego was bad on bare feet? Hoo boy
At least the UK one is blunt. I'm trying, without success, to find a picture of the old style telephone (and my modem) connectors we had here in Norway. Imagine the UK power plug, but the pins are pointy. I've drawn blood stepping on these. I would run a marathon on Lego to avoid stepping on one of those again. Luckily they were gradually replaced by wallmounted RJ11 (or RJ45 if you had ISDN) during the 90's.
EDIT: Found it.
Stepping on one feels like getting shanked under your foot by Poseidon and his trident.
Oh dude that's medieval lol
The UK ones are only safe from an electric point of view. As stepping hazards for shoe-less feet they are only slightly less lethal than Lego bricks
UK's are hilariously over-engineered. Might as well have a puzzle mechanism on the back, to make sure you really meant to power that toaster.
Breakers in every socket are a neat idea, though. And power switches at the socket make a lot more sense than US homes where some wall switches control some sockets, somewhere. Good luck!
The Brits have undoubtedly the best outlets from a safety perspective, despite their size. North American outlets are garbage by basically all measures. European plugs are weirdly round, but very functional.
My two (€/100)s
I'll just throw in one good thing for US outlets. The option of GFCI (Ground Fault Circuit Interrupter) outlets. I think it is required in bathrooms (or elsewhere 6 feet from water source), but you can probably install those anywhere you wish. It cuts off the power during a ground fault, which means that some current (more than regular leakage) is flowing to ground, perhaps through a human. It should cut off at just 5mA.
There's something similar in Europe, called RCD (Residual Current Device). It is the same thing, it's just that in US it's generally called GFCI and RCD in Europe. The difference with RCD is that it's not in the outlets, but the breaker box, and generally protects the whole home. But you can also wire GFCI to multiple outlets. The problem is, that trip ground fault current for RCD can be up to 30mA as opposed to GFCI's 5mA. And with 10mA and above, you may not be able to "let go" of the item shocking you, which isn't nice even if it won't yet kill you (probably).
Why is that? Leakage current. That could very well exceed 5mA when you have stuff like a desktop PC, fridge and other stuff connected, resulting in unwanted tripping while everything functions just fine. It also means that perhaps, one day, your fridge may save you by preloading the RCD as it wouldn't trip without it.
OK, now something negative about (some) EU plugs.
This should only work for devices that don't require ground due to pin thickness. But you can still get it to make a terrible contact and hold it in. But perhaps you could even force it into some. I dislike this.
Oh well. You can probably still force in older plugs that require ground pin yet don't have the contacts for type F sockets like modern plugs. It is also reversible which I hate. Sockets should be polarized. You shouldn't be allowed to just plug in the device other way around. If there is a switch, it definitely should disconnect live wire, not neutral leaving the device live but not functional. That's unsafe. I hate this.
This is nice. I like it. It would also be cool if there was a fuse inside the plugs cough cough UK plugs.
Re: GFCI's
At least in my country, GFCI's are required to be fitted in the fuse box, to protect the entire building. Not just rooms which are prone to ground faults. In the American type, the protection is optional.
Regarding Type F:
If you have a monopolar switch in your appliance, you dun fucked up real bad.
Reason is here in Belgium (and a bit of France apparently) and especially around Brussels, it's very common for houses to be wired with two phases (+115/-115V). This was done post-war for copper-saving reasons, and we call this 3x230V. So any device that cuts the brown wire only will still have 115VAC to ground, which is obviously unsafe.
Also more generally there is no guarantee that the live wire is on either side. From what I understand each electrician has their preference, and as long as the wiring is consistent then it's up to code.
So wherever there is an outlet, nothing can be safely assumed by the appliance besides that the total voltage is around 230V AC. Even assuming that there is a ground is incorrect due to old houses still having Type C (which incidentally means that even Type E also is not polarized when plugged into a Type C receptacle!).
I'm biased, from the UK. But it's pretty much the order I'd do it too. UK first, the round Europe ones only very slightly behind (maybe even on par, I have just a slight issue with the fact that polarity isn't assured).
The main thing that should get adopted everywhere is having fuses or breakers in the plugs themselves. That would eliminate a lot of fires caused by putting too much current through small wires.
I also like the outlets (like in the UK and probably other places) that won't unlock the mains slots until there's a ground pin in place.
Fuses should be required for any power strip that is not rated for 20 A (2.5mm² wires). At least where I live that's the highest current an outlet circuit can be rated for.
The power strips that cheap out and only put in 1.55mm²/16 A are stupid. For 20 A power strips though, fuses are redundant.
Modern European plugs are already plenty safe for "accidental" insertion, you have to push into both holes at the same time for the outlet to "unlatch".
I also like the outlets (like in the UK and probably other places) that won’t unlock the mains slots until there’s a ground pin in place.
That's... most places. Or better, they don't open unless you push in both prongs at the same time
That would eliminate a lot of fires caused by putting too much current through small wires.
The counterpoint to this would be: Why have the fuse in the plug (where the plug necessarily becomes bulkier and hence easier to break or harm someone by stepping on it, especially because the UK plug design means the points orient upwards on average) when you can have it in the device instead?
Moreover, why go the step of putting millions and millions of fuses into millions of millions of plugs instead of much fewer fuses on lines in homes? If you got to decree a fuse to stop overcurrent on the cable in the wall, put the fuse where you're trying to use it.
(I'm not against fuses in all plugs, I'm just saying it's easy to make counterarguments that it's both impractical and also the wrong solution to the problem)
The benefit of the fusebin the plug is you can have a 1A fuse for a 1A appliance with a cable rated for 1A, and plug it into a socket rated for 10A.
If the appliance faults, then the wire doesnt catch fire.
If you dont have that, then all the wires have to be rated to 10A (or whatever the rating is).
And thats based on 1-breaker-per-socket.
If you have 2 sockets close to eachother on the opposite side of the house than the breaker panel, its easier and cheaper to wire them both together on 20A cable and a single 20A breaker. The fuses in the plug protect the 10A cable to the appliance, the 20A breaker protects the 20A cable in the wall.
Yes, you could put a fuse in the appliance (a lot have this).
But that isnt convenient for lamps, where it might be bulky to include a fuse holder and ruin the aesthetic.
Or something that deals with water, like submersible pumps or kettles.
Also, some appliances have swappable cables (IEC C13 for example). So if the appliance has an internal 10A fuse but is used with an IEC cable rated to 5A then it leaves the cable unprotected and a possible fire hazard.
https://en.wikipedia.org/wiki/Schuko
I've used many plugs and in my opinion, the schuko plug is the one that makes the most sense.
Reverse Polarity (can't use it the wrong way, and you can turn it in case some power adapted is in the way)
also the symmetry makes it look more pleasing
only 2 pins stick out (the ground is in the body, 2 pins are a reduced area of failure in case you drop it.
very good and secure fit
I am going to argue Swiss type J.
It’s compact, safe, and easy to use.
Before anyone says UK I’m going to say they’re too bulky to be worth it. A usb charger for a UK plug is just so big and bulky that it’s not worth it. The Schuko plug falls into the same category.
If we are allowing future potential plugs I would argue for IEC 60906-1. It’s basically the same as Swiss type J but with very minor changes.
can we make a new thing? ie, i love what weve been able to do with USB-c as far as standardization... could we make a higher voltage, single plug 'thing'?
We could but the amount of time that would take would be ludicrous, and that's if you can convince people to switch. People don't like change.
Hell, the switch to USB-C isn't even fully complete. Sure, Apple finally did it after the EU twisted their arm, but some companies still release products with micro USB. Idk if it's cheaper or what, but it's definitely annoying.
i think the micro to usb-c is about supply chain. current production needs to run out the supply of the cheaper micro pieces. at some point it will be cheaper to use usb-c than micro and we wont look back.
If you don't feel pain when stepping on Legos for whatever reason, the UK plug is easily the best one.
I just wanted to throw the AU/NZ plug into the mix since nobody is really talking about it. I don't have enough knowledge about this kind of thing to really have a take on it, but I'm interested to get an international perspective.
Hey did you get that idea from the coffee shop thread? Someone was asking about weird outlets shown in a picture.
My answer for the question is obviously the UK standard.
My answer for the question is obviously the UK standard.
Also knows as the caltrop plug because it the damn things always fall spikes up and hurt whoever is trying to move through a room in dim light.
The correct answer is of course SchuKo plugs / CEE 7/7. If you check plugs used in the world you notice it has a huge spread of compatible plugs, as it can fit SchuKo plugs of two types and Euro plugs of two types. It also has all security features, including a raised ground that connects the ground before the power can come into contact.
It's tough to truly pull favourites with power sockets - you just use what you got - but if I had to pick one that'll be decreed to be used worldwide, it'd be this one. For sure. Note how the 7/7 variant has a lot of interoperability with other existing plug variations, too. It can for example use the french outlet-ground-pin, not only the german-style clamps, all with the same plug. Outlets can be designed to be compatible with swiss plugs, IIRC. Danish ones I'm not sure about, though.
The plugs used in the Netherlands, too lazy to look up what type it is.
They're well built, have snug fits, have metal only at the ends to avoid accidents, and I can go on for a while
The worst ones are the US ones that are also used in Canada and Mexico.
They. Suck.... Badly...
I've electrocuted myself on many instances whilst trying to plug something in the dark. They connect with so little focrce that half the time plugs just slip out of the socket because of gravity. Its a shit show
Getting shocked by 120v is a rite of passage as a child growing up in the US
IEC C13 socket with C14 locking plugs. Already ubiquitous in data center facilities. Rated for voltages between 110 and 250, so it works for any country’s common household current.
I'd go UK then NZ/AUS (Type I plugs). I may put our NZ/AUS ones above the UK ones on the size difference. and of cause they should all have RCD protection
I'm always up for a bit of controversy. I like the basic ungrounded American plug (NEMA 1-15).
It has no safety features. Just about every American has shocked themselves with it once, but very few have done it twice. I like it because it's compact, and that leads to some conveniences:
“Just about every American has shocked themselves with it once”
Um, no.
You haven't? I guess most people I know were dumber as kids that you were.
The British style is the best for ELECTRICAL safety, but stepping on a plug barefoot will make you wish you carpeted your bedroom in Lego. You will vomit out your pelvis from the pain.
The European ones are overall better imho. Just because of the plugs that go in them.
Seriously I have both stepped on a British plug and been hit by a car and the car definitely did more damage, and the pain was worse in the long term. But the initial moment of impact was worse when I stepped on the plug.
IEC 60906-1 (Type N). It was designed to be an international standard. It has no reverse polarity and is small but secure. It comes with all the important safety features and is also compatible with Europlugs.
However, the EU has sadly recommended against switching to this plug, citing plastic waste concerns from all our current plugs. However, Type N plugs have less than half the plastic of a Schuko plug. Someone should do the math and see if it would be worth it plastic waste wise to transition to Type N. Perhaps within 10 years, the savings that come with a smaller plug outweigh the plastic waste of older plugs.
There are so many well thought out features to UK plugs and sockets there is no contest.
Isn’t the UK plug like how it is because of the awful ring circuits in buildings built after the war? Otherwise could we have RCDs and overload protection at the switchboard?
As an Australian I’ll stand in solidarity with the UK on having switches for each power socket – immensely convenient.
I have no opinion on my country’s plug, it seems to work well and not grip loosely. But I’m open to being convinced that others are better.
I am convinced the Danish power socket contributes to national happiness.
For example, when you step on them, the plugs hurt a lot more than a Lego brick.
I find the love for the UK plug fascinating, as to me it's one of the worst designed pug types:
It's important to keep in mind that UK plugs were a necessity (ring circuits without circuit fuses in homes due to a copper shortage), not a desired result. They are good for what they had to do, but in times where the limitation no longer stops you from using a better plug style, they aren't needed and just add bulk and complexity.
