One might say that you will be grounded or brought back down to Earth 🙃

@qlp Thank you for inspiring the pinned comment I'm about to pin. Can't believe I hadn't thought of it!

I've been using that emoji a little too much lately, but it felt even more apt here
in reply to Technology Connections

Wow, that bit plugging it in a little and the light coming on is scary! What a terrible design - ours in Australia were a bit less susceptible to that already, the pins being at an angle to each other, but they fixed the potential problem (of maybe like sliding a knife or screwdriver in) anyway like a decade ago, changing the standard to insulate the pins half way for any new plugs.

An interesting thing about our plugs is that they’re usually ground pin down, but China used basically the same design but put them upside down, so if you buy something direct from China that comes with a right-angle plug, the wire usually comes out the “wrong” way!

“Nobody cares”

Irate, mostly because, if code doesn’t require it, it’s opinion. But once you gave the “nobody cares” disclaimer, you got a pass, at least from me.

You can flip my surprised-face power outlets after ripping them from my cold, dead hands!
in reply to xbezdick

@xbezdick At this point I think almost any receptacle design is better than what we're stuck with.

However, I don't like that Shucko has no polarization. That is the only thing we can claim as superior. The whole rest of it? All sorts of bad.

in reply to Technology Connections

@xbezdick What is the usecase of polarization for AC sockets anyway? Times of directly driven AC motors are long gone, even longer for applications which aren't hard wired.

Serious question. There is a possibility, that applications in need or polarization just non existent around here, because Shuko is the norm around here.

in reply to gom

@gom @xbezdick Well, it's pretty in-the-weeds but there are two main reasons: one, appliances can use a SPST switch and not worry about live wires within, and two lamps with Edison screw sockets are a lot more dangerous without polarization.

But, you could easily argue (and perhaps it's correct) that DPST switches are enough to alleviate the issue.

Personally, though, not defining one side as hot and the other as neutral gives me the heebie-jeebies.

in reply to Technology Connections

@xbezdick
Thanks for your answer.
All lamp holders I'm aware of are 2 pin europlugs and I'm not aware of 3 pin NEMA plugs, at least not for edison types. Having polarized NEMA sockts won't change much. Also SPSTs are only "safe" assuming, that no sparky has messed up the wiring, which is a bolt assumption I would not count on ever.
And for all the folks touching bare mains contacts, RCDs are required for reasons 😀

@gom @xbezdick You'd be shocked to discover that we don't allow Class 0 devices running on >150V AC.

In EU you're not allowed to sell a Class 0 consumer appliance for about 20 years now, and Class I/II devices were popular since mid 80s anyway.

This usually means no exposed metal in E27/E14 lightbulb sockets when the bulb is installed (they're ⧈). So it doesn't really matter if it's SPST or DPST, because an average user won't have contact with L or N in normal circumstances.

in reply to xbezdick

@xbezdick I feel like one of them that isn't solved is "someplace to plug something in". This plug is so different from anything I've seen I'm not entirely sure how to use it.
in reply to Mark

@mark This is either a bad picture or there's something weird going on.

@xbezdick

in reply to xbezdick

@xbezdick @mark OK, that makes slightly more sense. My NEMA-conditioned brain sees the (presumably) ground pin sticking out and that screw sticking in and gets confused, especially with one plug angled and the screw being located inside a socket.
in reply to Technology Connections

My main concern is metal things falling off the back of a table/desk, like a pile of coins or something. To fall down they would already be somewhat vertical and outlets are often in use behind such fixtures.
in reply to gudenau

@gudenau Then you better make sure it's a power strip in the top plug because if it's a two-pronger it won't help
in reply to Technology Connections

I do think about such things, if I could flip them I'd definitely put grounded stuff on top!
in reply to Technology Connections

Adding insulation to the top of the L/N prongs is something that was done in the UK a few years ago; if you look at older UK plugs they don't have it. I'm not aware of any compatibility problems. And we normally have earth at the top as God intended.
in reply to penguin42

@penguin42 I think the challenge we face is that the bite point on most receptacles isn't very deep at all, so whatever insulating material we added would get scratched up and/or cause a bad connection.

We could definitely add /some/ insulation to the blades, and I think we should, but I'm honestly not sure we can add enough to truly nip the problem in the bud without causing other issues.

in reply to Technology Connections

@penguin42 presumably we could update the national electric code now to define bite depth rules moving forward so that in 20+ years we can add (more) insulation but no one is going to be willing to play that kind of long game.
in reply to penguin42

@penguin42 The Australians managing to insulate is probably a bit of a better example, the UK one is the size of a planet. I wouldn't be surprised if someone's managed to fit a raspberry pi into one.
in reply to InsertUser

@InsertUser Look, if you can't fight off an attacker with one, your plug just isn't worth it.
in reply to penguin42

@penguin42 Oh. Some of the chonkier 240v and 3-phase plugs we get in the states would certainly qualify. You get someone in the face with one of those bad boys and they stay down.

@InsertUser @TechConnectify

in reply to Baloo Uriza

@BalooUriza @penguin42 @InsertUser UK plugs make *fantastic* caltrops.

*Really* puts Lego to shame. No competition.

in reply to Technology Connections

I'm sure this is covered in the video, but my favorite thing about the whole debate is how it really doesn't matter if you install the receptacles ground up or down because so many plugs don't come with a ground pin.

Space heater pulling 1500W? Go ahead and just use hot and neutral, who needs ground? 🤡

in reply to Technology Connections

It was only a brief mention in your video, but my home-electrical hill to die on is that Chicago code "conduit everywhere" is _so_ useful.
in reply to JRandomHacker

@jrandomhacker I think I dislike it more than I like it to be honest as adding new branches is much more of a pain.

However, I have now come to the opinion that the sideways outlet convention is absolutely the best way to do it - if neutral is on top, that is. In my new home, literally all of them have hot on top so...

in reply to Technology Connections

@jrandomhacker

Why do they require conduit! That's crazy...

I say living in a house that appears to have double conduit for all electrical....Europe is weird, but I think this is more of an artefact of concrete construction than anything else.

As for sideways plugs, I always thought those were an artefact of early electrification when they were installed in the baseboards.

in reply to Daniel Brotherston

@danbrotherston @jrandomhacker It's some combination of pressure from electrical unions and intense paranoia from the Great Chicago Fire.

And I'm not kidding about the paranoia - Chicago has way more brick houses than typical, and even plenty of suburbs have building codes requiring masonry or brick for anything larger than a townhouse.

@miah It's hard to say, but my position is that the main thing we need to solve is the plugs-backing-out problem, and right-angle plugs are a better hedge against that imo as they help regardless of whether the ground pin is present.

Sleeving the blades, too, if we can make that work would be good.

My main beef with the ground-up "solution" is that it's only sometimes a solution and doesn't actually address the biggest problems.

in reply to Technology Connections

I know you've done a video on it before, but can I just gloat about British Standard plugs and sockets, which literally address all of the issues you raise with your silly north American plugs and sockets (including pulling the plugs out of the socket if they're properly compliant).
in reply to Craig Stewart

They also have a very easy way of remembering how to wire them. The BRown live wire goes to the Bottom Right, and the BLue neutral goes to the Bottom Left.
in reply to Technology Connections

As someone who's had to get used to the jumbo British ones I'd just say that right angled plugs hurt SO MUCH of you step on one, I'm not sure I like the thought of an even pointier version.
in reply to Technology Connections

I'm... torn.
Aircrafts should be known for following any spec and norm, and yet the one I'm on has but correct and wrong orientation of the sockets.

Technology Connections reshared this.

in reply to Technology Connections

Electrician from Denmark here.
The orientation of the plug is not something the code specify over here. That’s something the manufacturer has to specify in their datasheet of the product. If it isn’t mentioned, it doesn’t matter and you are free to do as needed.
Also our receptacle is recessed to further idiot proof the setup, along with plastic on the prongs. Oh and RCDs.

EDIT: not all prongs have plastic. Actually mostly on 2 prongs.

The last house I lived in had Edison wall sockets. Literally a light bulb screw socket in a wall outlet. This was apparently because the Edison bulb was a de facto standard long before the electrical plug had any standard form, so appliances often just had a screw base on a wire!
in reply to Technology Connections

I've often wondered why we in the US cannot get a standard on jacketed plugs with a 1/4" of insulation from the base outward on 5-15P and 5-20P plugs. I'm probably missing something wildly obvious with that.
in reply to Technology Connections

are you saying that Quebec electricians have been RIGHT ALL ALONG??

in reply to Technology Connections

Relevant to this video, this might be interesting to you: in Delaware, our house (and most other relatively new-ish builds) had one outlet in each room upside down. This indicated which outlet was controlled by the wall switch (e.g. one of the 2 or 3 rocker light switches). That way you could plug in standing lamps, and control them using the wall mounted light switches.
in reply to Technology Connections

I absolutely lost my shit at the “throw the knives at the wall” section. Laughed so hard I cried, and it’s been a while since anything on YouTube had that effect on me.

Now if you’ll excuse me, I’ve got a cutlery drawer that needs emptying.

in reply to Technology Connections

I used to say that. I bet you say this in the video I’ll watch shortly, but the other way is the de facto standard. Good luck finding a night light, low profile plug, or blow dryer with built in gfci that fits right in a ground up receptacle

in reply to Technology Connections

I take the flange for granted but holding older plugs really does feel iffy.
in reply to Technology Connections

The weirdest plug orientation I have. Course it makes sense once you realize that this is on a window air conditioner so the wire has to go towards the window but another tick towards ground towards the bottom. It's also about 20 years old and has been used in a garage so please excuse the crud encrusted in it!
in reply to Nick from Toronto

Being British, the existence of non-right angle plugs is another one of those jarring things about international travel
in reply to Technology Connections

hmm, I'm gonna watch this later. I'm guessing we go nowhere near the refrigeration cycle or latent heat this time?
in reply to Technology Connections

Ha! The electrician that rewired my entire house 25 years ago put the ground pin up *everywhere* and said that it was for safety, and cited the "foreign object falling on the pin" as the reason.

He was the best, fastest, most knowledgeable, and hardest working electrician I've ever seen (multiple other subcontractors told me the same) so it's now gospel to me.

in reply to Technology Connections

I’m an English major, but my spouse is an electrician and a PE. I’ll have to show him this.

What bugs me most about plugs is trying to fit different ones into an outlet when the plastic casing is blocking BOTH receptacles. Outlet strips are a particular chore—you have to carefully plan which device uses which receptacle.

Anyway, great video (any complaints from Bostonians??)

in reply to Lynn McKenzie

Another advantage of the British plug, they're so big to start with that you never get an overlap with transformers.
in reply to Technology Connections

got a unicorn for ya! I don't remember where this extension cord came from but I can tell you it's really obnoxious.
in reply to Technology Connections

Electrified by this comprehensive analysis! Yes, totally geeking out here. -- Daughter of an electrical design engineer.
in reply to Technology Connections

as someone who did an electrical apprenticeship in Australia, these outlets have always appeared insanely bad to me. We have much wider and more secure plugs, the angled pins prevent sagging/bumped plugs, and the insulated pins prevent anything slipping between the plug and socket causing a short. Oh, and there is no upside down orientation! Assuming you ignore the Chinese sockets, which are upside down versions of ours...
in reply to Technology Connections

Great video, but when were describing the "very specific scenarios" I couldn't help but imagine... 🤣🤣
in reply to Technology Connections

The real achievement would be to annoy a superset of electricians.

I guess that would be every electrician in the world, and also possibly some other people.

in reply to Technology Connections

These go the other way but as long as the cord hangs down I'm happy. I have a buddy who's welder has the cord coming out of the plug on the top side, then bends to drop to the floor. It drives me nuts. He won't let me turn it around either. I'm going to have to break in and flip it.
in reply to Technology Connections

is there a code reason pins in the US don’t have sleeves, or is it just they aren’t required so nobody bothers? Seems like such an obvious and trivial safety feature.
in reply to Alec Perkins

As touched on in the video, the standards over there don't define a specific location for the connection point within the socket. So if it's near the front it won't work with sleeved pins.
in reply to Technology Connections

I’ve only seen this design once, but I love it for the give-more-control-as-you-un/plug issue

in reply to Technology Connections

I don’t know what you’re talking about; in my 1979-built house all the outlets are sideways! 😅
in reply to Technology Connections

So out of a fun coincidence I happened to get an old Montgomery Ward Radial Arm saw from my grandfather, including the original manual, weirdly enough.

Inside is this picture, which is relevant and makes you wonder.

in reply to Technology Connections

FWIW sleeved plugs like this are common in Japan now and I haven't noticed any compatibility issues.
in reply to Technology Connections

Some genius previous owner flipped all the outlets in my house, leading me to this TOTALLY SUPER SAFE setup.

hot take: we should have both oriented so the "face" is facing away from the other, so the top one is "upside down" but the bottom one is "correct"
in reply to Technology Connections

Nothing makes me feel more supperior to stupid americans than the use of #Schuko-plugs! No, not even using the relatively sane metric system!
in reply to Technology Connections

it's weird to see this as in the EU we have Type C for ungrounded and both Type F and Type E for grounded, the last one is usually installed with the ground pin up which I have never seen shielded and comes out of the socket.

both Type C and F never care about orientation unless a type E socket is used in which case the ground pin would always fit on the top.

additionally pins on Type C are always insulated; but for Types E and F the socket itself should be recessed far enough that contact should not be possible when the pins are accessible (although older construction is not always up to code with this; but then we also have Type C sockets that accept E and F even though there is no grounding).
nowadays in new construction the grounded Type F (or E depending on country) is required and Type C sockets (not the plugs) are illegal to build.

PS: I used the types from this site documenting the plug standards around the world: https://www.worldstandards.eu/electricity/plugs-and-sockets/

in reply to Technology Connections

A question I had while watching the video was why there don't seem to be any options for horizontally oriented type A/B outlets like the ones I've mocked up below?

I live in a type G country where this orientation and right angle plugs are standard so please correct me if I'm mistaken and you can actually buy type A/B outlets like this.
