@TechnologyConnections 2 роки тому
No I'm not on Electrician Talk, but I've noticed that pretty much every commercial building I've run into lately has them installed ground-up, and the printing on every receptacle I've encountered is right side up only when the ground pin is on top. Even the GFCI outlet shown here with the power switch, which is ~ 10 years old, has the "TR" logo upside down because it was installed ground-down. For the record, I don't care about this, and until manufacturers of 90 degree cords and wall warts start making them to work with ground-up installations I'd still want the standard "face" orientation in my home. But it seems pretty clear that it's frowned upon, if not explicitly wrong.

I have lived in a few rental properties with what I always called “butter plugs” most of them were quite old and probably had dozens of people living there over the decades. And well, as you noted in the end, probably just wear on the sockets. Never to the point where they would fall out without help but they usually weren’t hanging on very well. The US has so much cheap crap nowadays. I had a unit where one of the light switches was sparking when I tried to turn it on and off. One unit the fuse box was sparking randomly. Apartments use all the cheapest things in them. It’s genuinely terrifying to think about.
@Staratopia 5 місяців тому
What's scarier is a lot of newer homes are also built with cheapest options with the expectation that who ever buys the house will remodel everything, but the buyer isn't informed of just how much they should remodel. This especially seems true for low income houses in cases where the buyer will be less likely to afford the remodel.

I have encountered sockets where plugs absolutely would not stay in the socket. It's especially problematic with heavier plugs like USB cubes, scent plug-ins, or those big boxes with the lil wire coming out (as you can see, I'm layperson 😅). You plug it in, and it slips right back out without even touching it. I believe I've had some in my apartments (up in Indiana, don't think I've struggled in my place in Georgia, but I've only been here about a year), and I've absolutely struggled in hotels/motels. I think he addressed this in a later video and hypothesized it was due to such frequent use, which I'm inclined to believe. I typically go hunting for a socket that sticks, or I have to get an extending cord and plug everything there. Actually... now that I think about it one of my current extention cords is very buttery (thank you for the new lingo!), and my phone chargers are constantly coming out, and that sucker is parallel to the ground and command stripped to my night stand at head level, so there's no wild angles putting unnecessary strain on the plugs!

For like $10 you can get a tester that will tell you if an outlet has power and if its wired correctly).

I think I just always assumed that the holes were a cost-saving measure - it's only a bit less metal, but even something like 5% less material used in manufacturing adds up over millions of units.
@ryanschmidt1437 Рік тому
Those blades are most likely manufactured by a subtractive manufacturing process called punching; a positive shaped punch (looks like the blade) and close-fitting negative die come together from opposite sides of the sheet stock and shear through it faster than you can blink. Subtractive manufacturing means you start with more material than you need to make the part; the extra is waste. Sure, those hole blanks are a tiny bit less material in the useful part, but that waste material required energy use to melt, cast, and roll it into the sheet stock that blade was punched from, and the waste has to be recycled in order to be useful again later, thus requiring application of energy twice before becoming an actual part. Then there's the energy it takes to punch it out, just to "throw it away"; not much energy in the scale of things, but not negligible. It also requires more complicated tooling design to remove the material, which isn't cheap either, in both production and maintenance. Depending on the type of punch press blanking the blades out, the holes may either be a second punching operation, a complicated concentric 2-stage punching die, or a die set through which the material advances, simply being struck twice in different areas of the die. Manufacturing processes always require time and energy to perform, which costs money, so removing that material has to serve a purpose or the energy expended on the feature is a waste of money.
@ratkingcrab Рік тому
@@ryanschmidt1437 your response makes a lot of sense. is it possible that the material from the holes is simply more valuable than the energy cost of recycling the 'waste' parts created by punching them out? making it more cost effective to punch them out and melt them back down than to buy new material over time?

This video is years old and this has probably already been mentioned, but the holes also save on material. Sure, probably very little, but when you can squeeze a few more units out of a run, it seems like a no-brainer. When you can get an extra blade every 999 or 9,999 blades, it seems worth it.

By using a ball bearing inside the outlet, kind of like how a ratchet locks a socket in place, could be a great way to utilize the holes and keep the plug from being removed accidentally. Then when you want to disconnect from the outlet, just press a button on the face to take the pressure off of the ball bearing, which would allow you to easily remove the plug.
@holyhalfdead 3 місяці тому
Ball bearings on reasonable stiff springs would hold the plug in the correct position. The ball bearings and springs do not need to conduct the electricity, the usual contacts would be used for that. It would require the same amount of force to remove it as it did to plug it in, so I don't think a release button would be necessary. This could well have been why the holes were created, but the additional cost of adding two ball bearings and two springs to every socket would be why it never caught on. In any situation you should not pull out a plug by holding the wire.

Once, I needed a longer electrical cord and didn't have a complete extension cord to use. The cord I had was missing the female socket. So I stripped the wires on the cut end and used the holes on the male plug's prongs as a place to loop them through for a secured connection. I soldered them and wrapped them with several layers of professional electrical tape which is made of rubber and stretches. I've been using it for years. So I found a use for those holes.

For manufacturing alignment in molded plugs, having the holes identical across competing pin suppliers is important to get the right size . One way to reduce the risk of touching live is to sleeve the pins like in the 13A British plug and the 2.5A Europlug . This requires the stem of each pin to be slightly thinner so the sleeved part of the pin is no thicker than the exposed tip, thus with folded-over metal, the stem would be narrow and single layer . The length of the sleeves need to be standarsized by NEMA, while the manufacturing techniques would be shared with all other bladed plug types (Australian, Japanese, Chinese etc.).

There are some commercial plugs that do have index nubs which fit into the holes. It makes the plug legitimately difficult to get out. They're meant to be used for plugs on the ceiling. It keeps cables off the ground so they're not a tripping hazard and the cables can hang down without falling out.

I actually discovered the exact wiring error hinted to at 2:05 in my house, when I was (I think) less than 8 years old. My parents, who knew I could be trusted to stay safe, had given me an outlet tester to mess around with. (I was an interesting kid, and I liked things with lights on them.) I proceeded to plug it into outlets all over the house, much like TC did with the lamp cord, only ever seeing both green LED's light up. That is, until I got to the ones in the basement. When I plugged it into any of those outlets, only one of the green lights turned on, as well as the orange one, which I was excited to see lit up for the first time. "Oh, how interesting," I thought to myself, looking at the sticker with the light combinations to see what it meant. It said that this pattern means "Hot/Neutral Reverse". Now, I had no idea what that meant at the time, but since this was called an "outlet tester", I correctly reasoned that it must mean something was wrong with the outlets. I told my parents, who were previously unaware of this issue. Some time after that, we had an electrician at our house, and one of my parents mentioned this to him. Sure enough, he confirmed (and fixed) the wiring issue.

Excellent explanation in this video. I did electrician training during the mid 1960s. The basics are the same, but the devices and some of the standards have changed since then. I am in my 70s now... I have bought some devices where there were no holes in the plug contacts. From what I was taught is inside the outlet are a small rise or bump or dimple inside the contacts that squeeze the plug contacts. This offers a bitter grip to help prevent the plug from falling out of the outlet. There are some types of socket units where the contacts are without any bump or dimple inside. The pressure of the contacts is holding in the plug contacts. The idea of the polarized plug is to have the ground on the chassis or frame side. Fully electrically isolated devices where the electronics inside are electrically floating technically don't need a polarized plug. Many of the small wall chargers don't require a polarized plug.

Brit here. Until this video kept coming up (and yes, I've now given in and watched it), I wasn't even _aware_ that (a) US plugs _had_ those holes (b) they were polarised; I think the only ones I've seen have been in adapters or multi-country plugs, which mostly don't. As for being able to touch the live pins of a partly-inserted plug, ours - both the old round-pin (commonly known as "5A" and "15A"), and the more modern square-pin (BS1363, commonly known as "13A") - had the same problem. A revision introduced in I think the 1970s "shrouded" the part of the "pins" closest to the plug; obviously that means the actual pin was thinner, but by that time, fewer appliances were drawing the full 13A (in fact the plug seems ridiculously oversized for the majority of appliances), so it wasn't the problem it might seem (though for kettles and heaters that still draw the maximum, good quality plugs are needed). I think it's now actually illegal to sell anything with an unshrouded plug, though you may still find some in some second-hand shops. I don't _think_ it would be practical with the already-thinner US pins ("blades"), but it might be possible to add the extra on the outside - but then some older sockets wouldn't accept the new plug blades. (I did wonder if at some time homes - and workplaces - might start to come with a lower voltage as standard, with the high one for just hight-demand purposes: when that seemed possible, 12V might have worked. [Now probably 5V.] But I guess the extra wiring complexity hit that on the head.)

When traveling, a small roll of tape with aggressive adhesive has many uses. Duct tape, gaffer's tape, aluminum foil tape.

Locking extension cords. I have 2 of them that I lock with a button end to end for my grass whipper. They don't disconnect when locked. Also, locks in drill cord. Very useful.

Can't believe you're the first comment here referencing this. It's common in construction to have locking extension cords, so the don't come apart while dragging your saw or drill around.

Wait that right side pin is LIVE? I can't even imagine how many times I've almost touched that damn thing trying to pull a tight plug at a weird angle

As a child, I once wondered what would happen if I laid a small nail across a partially inserted plug. For the next 10 years I lived with a spot of molten metal splashed onto the hardwood floor to remind me of the answer. Oddly it was a red dot. My parents never grilled me for an explanation.

Coming to America from Britain where everything is overengineered I was amazed at the flimsy domestic plugs and outlets.

In Japan we have some outlet where you can rotate the plug 45° to lock it. Could be interesting to see how the lock system work. Maybe they use those holes …

It’s for lock out tag out, so you can attach a lock and prevent someone from plugging it in but also pretty sure it’s just part of the manufacturing process lol

A locking-socket extension cord turned up in my store last month. It has a sliding sleeve which causes two pins to engage those holes. Works a treat AFAICT.
