Maybe some day I'll talk about the fact that all these outlets are technically upside down.

Seeing a US wall socket looked so… naked to me. I can't get over how they have no switches on them, seems a bit dangerous (especially considering you're plugging them in so slowly while they are live) and very inconvenient, also energy wasteful for electronics that stay on standby like TVs.

if it was for a detent and your plug didn't have holes. The contact to the blades would only be on that bump. Very little contact surface

Man, I'm not sure the term "dangerous" is meant to refer to situations where humans and children are doing shit they ain't 'spose to be doin'. Sticking your fingers in a light socket is dangerous. The act of f'in around is dangerous, not the actual inanimate object. Before anybody says it, this comment is not intended as an analog to any politicized issue.

My 2 theories were that it would help with lining-up in manufactures and that over large-scale production on millions of plugs that little amount on metal that is saved on each plug do add-up an can be used for other things (or even more plugs! :D)

I guess you haven't had the time to download a free copy of the NEMA standard to read it, right? That is clearly stated there that the roles on NEMA-1 (NEMA 1-15P) plugs are optional and meant for manufacturing purposes only. In the other hand, there are other NEMA plugs and receptacles (locking types) that use those holes (For instance NEMA L19-30), but they are all twist-lock, so flat blades won't fit there.

peace.

Are the holes not there so you can tie tag a WARNING message on the device that you have to read/remove before you use it?
Also an electrician could use a tie tag to prevent a plug from being removed, if it was for example a hotel?

Alot like luxury models of American automobiles having sun / moon roofs that no one uses . I realized during my two week trip , that my suv had one and would have had better potential for internal storage if it wasn't there .

That Goth Guy 14/10/2021 - 9:50 PM

Most the world don't need to polarise the pins because all our devices have three pins and here in the UK the socket will not open without the third longer earth pin (they also have fuses).

military uses the design for lock out tag out. so does osha. but does not really matter. one of NFPA standards is the plug must be able to be pulled out at min 3 pounds pulling force. so if someone trips on a cable it will unplug and not damage or expose the wires.

Hazzer2007 14/10/2021 - 9:50 PM

I thought it was for "Lock out, Tag out" by putting a small padlock in the hole so someone doesn't plug in the device while it is being worked on

vaughn tonkin 14/10/2021 - 9:50 PM

I thought of the holes being there to clean the contacts in the power point each time the plug is inserted and removed, now onto the Australian plug, the outlets have the earth on bottom and live on top left. The old 1970's CMA brand plugs had the holes on the 2 upper pins

There's no on / off switch on American power points ?

19:22 "at least it's not 240V coming out of there" Seriously confused if you're making a joke, but in case you're not: that wouldn't change a thing! Instead of one prong at 120V AC and the other at neutral, you'd have both at 120V AC with a 180 degree phase shift. In fact (as you know) 240V would be in some sense safer since you only need half the current for the same power.

In japan there are wall plugs with 30° rotation (like a key) that lock the plug inside. Mostly for the outside stuff or the ceiling power outlets needed for point of sales. Think they use the holes for locking.

Doug Mac Lean 14/10/2021 - 9:50 PM

I used to worked in a factory for over 8-9 years have you ever heard of a lock out system? When things break down and needs to be worked on, normally you would lock out the electrical box to keep the worker safe from another person turning the machine on while they work on the machine. Weather it is Electrical or Machinery.

Same would apply with the plug if you run a zip tie through it you should not be able to plug it into an outlet, if there is something wrong with that item (Lamp, Stereo, Toaster, TV, Washer….. etc.) that is attached to that cord to keep people from using it and safe.

Problem is majority of people who did wonder about the holes never would give it a second thought about it anyways, and would normally replace the item if it did break down and is of no use anymore.

I haven't read through all your comments but, from what I know of on the holes on the terminals on the plug.

In Chile (South America) we use type L and I agree that it is the best plug that exists, since it takes up little space, is very safe, and is reversible like USB type c, you can connect it however you want.

I'm European and don't even use these plugs but this video still was very interesting. At 1:18 I understood why our thin plugs have metal only on the tips. "Everyday object" design is fascinating

Matthew Keller 14/10/2021 - 9:50 PM

just wanted to bring to your attention that there are electrical cord designs that utilize those holes to lock a plug into place so they don't get unplugged while pulling cords around on job sites.

sorry they do just fall out of the wall most countries plug prongs are also insulated and have an on off switch and a fuse at the wall. and will never fall our or be pulled out even after 100 years the plugs are very poor and shabby in america. i can hang the weight of a power drill or angle grinder from the retention of the plug from the wall where im from. in america there is no plug when this staying power even when its new. please travel more and compare other nations plugs and youll suddenly realise your plugs fall out all the time..

This may seem crazy but I would suspect that manufacturers would like the cost saving in fairly precious material (brass), despite
being just two small holes, as a percentage of material weight when looking at tens of thousands or millions of pins in manufacture, the hole would
represent a worthwhile, free and significant cost saving that doesn't ever get questioned as a 'cheaping out'.
Those couple of grams of metal also work for shipping costs at both ends of manufacture.

production cost of these extension cords must be super low compared to the sell value holy moly…

Reply
Jeff Houle 14/10/2021 - 9:50 PM

I'm not sure what the holes are for but anytime I find myself asking these questions, I always assume it's money related. Maybe the manufacturers are saving some money using less material.

Reply
Stephan S 14/10/2021 - 9:50 PM

There may be another point of these holes: Saving on production costs. Imagine producing (let's say) 5 million of these connectors and saving one or two grams of material on each connector. That is really some money when produced in high masses.

In my opinion they are for restricting your children from using their plug in devices! you can thread in a small locking device to disable them for time outs!

very strange. I bought a little no-name audio amplifier off Amazon last year, to power speakers on my porch during halloween. the power plug connected to the amp has no holes in the plug blades. This is the only time I remember seeing this. The plug blades are very loose and will fall out easily. I have to keep it plugged in vertically to an extension cord. I thought it was because of the smooth blades. Maybe this cheap little device has blades that are not only missing holes, but are the wrong size / thickness too. luckily I only keep it plugged in for a few hours, once a year.

Most norwegian plugs make it just as easy to touch live prongs as american ones.
And that's 240V.
