Check the comments of the original post for the stupidity.

For those of you without an electrical background, the diagram shows the protective earth connected directly to phase, with phase and neutral also joined.

Correctly wired, this would be a three pin plug, with the earth wire connected to the earth pin in the plug, with the other end connected to the metal casing of the appliance. This is a critical safety feature, which will cause the circuit protection to trip in the event a phase wire contacts the metal of whatever this is connected to.

If this was actually done, the most likely outcome is it would trip a circuit breaker, but if the neutral was broken, it would connect phase directly to the casing, and likely electrocute someone.

Or explode the plug in someone's hand, depending on the circuit breaker and the wire gauge

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago (2 children)

On a domestic plug the chances of injury are low, but not zero. It would definitely damage both the plug and socket, possibly burn your hand, and definitely be an exciting moment.

[–] balsoft@lemmy.ml 0 points 7 months ago (1 children)

I've had a cheapo electric kettle plug explode in my hand due to melted contacts in the base touching each other (I'm not sure why the plug exploded and not the base, probably a shitty connection in the plug). I didn't get injured but it was indeed quite exciting.

I had a cheapo Chinese charger explode in the socket. It was indeed quite exciting.

If done that way, it wouldn't even fit into a socket. Prongs are rotated 90°

[–] balsoft@lemmy.ml 0 points 7 months ago

Huh, yeah, you are right. I'm not from the US so it didn't immediately jump out at me

[–] hildegarde@lemmy.blahaj.zone 0 points 7 months ago (4 children)

everything about this is wrong. the most fundamental part is the fact that you don't wire north american plugs. Wiring your own plugs is a british thing, hence why the case is shaped like the british plug.

[–] i_am_not_a_robot@feddit.uk 0 points 7 months ago (1 children)

In fact it was compulsory in Britain until the 1980s/90s. I'm not sure exactly when it changed, but the reason was due to different electricity companies having different sockets (and therefore plugs). It was standardised way before then, but I guess if that's the way it has always been done nobody thinks of changing it.

[–] jabjoe@feddit.uk 0 points 7 months ago

My oldest (15) was just taught how to wire a plug at her high school. We're in the UK. I don't think I was (90s), but my dad will had shown me and I don't remember not knowing.

[–] Steve@startrek.website 0 points 7 months ago

Home Depot has a whole big shelf of north american plugs that anyone can wire up however they want.

[–] higgsboson@piefed.social 0 points 7 months ago (3 children)

you don't wire north american plugs

I don't? Please, do go on. I am interested to know how all my appliances apparently work by magic.

[–] EpeeGnome@feddit.online 0 points 7 months ago

Well, yes, someone wires the plugs at the appliance cord factory, but unless you work in appliance cord manufacturing it's typically not the appliance user. And yes, there are exceptions, such as installing some heavy appliances or replacing damaged plugs, but that's not typical for "all" of someone's appliances.

[–] hildegarde@lemmy.blahaj.zone 0 points 7 months ago (1 children)

North american plugs are not serviceable like british ones. The contacts are molded in plastic at the factory.

Opening a plug to service the wires is not possible. They don't open, nor do the plugs have fuses.

I'm interested to know how you are wiring plugs... and why. They are sold pre wired in my area. Are they not in yours?

If it would be done exactly like in the picture nothing would happen, as the only wire going in is the ground wire.

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago (1 children)

I know we're famous for not reading the article, but you didn't even read the post.

[–] SW42@lemmy.world 0 points 7 months ago (1 children)

I just looked at the picture and the only line that goes to the plug is the grounding wire.

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago

Your comment is nearly identical to one made by someone in the linked post, and I'm pretty sure you're trolling at this point.

I won't be engaging any further with you.

[–] Ephera@lemmy.ml 0 points 7 months ago

In case you had the same brainfart as me, it's a plug, not an outlet, so there could be no wires coming out of it and you could still short-circuit the outlet you plug it into...

[–] viking@infosec.pub 0 points 7 months ago (1 children)

You're correct, and people are morons.

[–] Successful_Try543@feddit.org 0 points 7 months ago* (last edited 7 months ago) (2 children)

It's a plug, not a socket. By inserting the two shorted pins (white wire) into any socket, you would essentially short the live and neutral connectors of the socket.

[–] viking@infosec.pub 0 points 7 months ago (1 children)

Correct, so you'd trip a breaker. You wouldn't however electrocute yourself.

[–] Successful_Try543@feddit.org 0 points 7 months ago (1 children)

If this was actually done, the most likely outcome is it would trip a circuit breaker, but if the neutral was broken, it would connect phase directly to the casing, and likely electrocute someone.

If the neutral wire is faulty, the live wire is connected to the ground wire and subsequently to the casing of the device. Thus, if somebody would touch the casing, the current (maximum what the breaker permits without opening) would flow through that person.

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago (1 children)

I really thought I explained that in a clear and simple manner.

Apparently not.

It is long overdue that those companies can be held legally responsible for what their AI produces.

If i had drawn up and published such an image, I probably could be drawn in court. Time for AI companies to fall under the same rule.

There have been cases of people poisoned, people looking for psychological help getting recommended to commit suicide, etc.

Time to drag those companies in court.

I've wired plugs with like 12 and a large part of our house with 14 or so. Ofc, with my dad and depending on the circumstances a qualified electrician checking, but no matter how wild it got, I never made a mistake

How are there people needing help to simply wire a plug? The hardest part is to open that damn thing!

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago (1 children)

Someone replied to me saying this picture of a plug is a dead circuit, because nothing is connected to anything, they genuinely don't seem to understand what a plug is.

They walk among us.

[–] Speculater@lemmy.world 0 points 7 months ago (1 children)

To be fair, this circuit is absolutely safe at long as the breakers are installed.

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago (1 children)

And the neutral is unbroken.

You're putting a lot of faith in the rest of the installation.

[–] Speculater@lemmy.world 0 points 7 months ago

I was being tongue in cheek. This will pop the circuit breaker, but to your point, may cause a fire with the insulation of the neutral. So I admit, it's not "perfectly safe." Lol.

[–] SketchySeaBeast@lemmy.ca 0 points 7 months ago (1 children)

Ofc, with my dad and depending on the circumstances a qualified electrician checking, but no matter how wild it got, I never made a mistake

This is you saying you got help wiring a plug.

What if people don't have their dad or a qualified electrician to check? They need help from somewhere. AI is a stupid place to look for it, but people need help doing things they never have before. Would you prefer they guess?

[–] 30p87@feddit.org 0 points 7 months ago (1 children)

I never had a simple plug or socket checked after my first five or so. For larger networks, I just shared the plan I made in my head. And the qualified electrician was there once, for the HV lines, as legally required.

Also, not guess, but know. It's very easy, especially plugs and sockets. Switches I can see someone pulling up the manufacturers docs to check which contacts are interconnected.

[–] SketchySeaBeast@lemmy.ca 0 points 7 months ago (1 children)

Yes, after your first five, but before that you needed help. If this is someone's first what are they do to? How are they supposed to know without getting some sort of help?

"It's easy, just do like my dad showed me!* isn't helpful if they don't know your dad.

[–] 30p87@feddit.org 0 points 7 months ago (1 children)

My dad did not help me. Plugging in three strands where they obviously belong is not something someone needs help with. Again, he checked the end result. As in, one glance at the result the first time and plugging the plug into the socket in the first few times, because at age 12 an electric shock is much more problematic than at age 36.

[–] SketchySeaBeast@lemmy.ca 0 points 7 months ago* (last edited 7 months ago) (1 children)

Your dad helped you. My whole point is you can't say people shouldn't need help when you got help.

[–] 30p87@feddit.org 0 points 7 months ago

Because I was 12 and had not one hour of physics class or anything at that point. The people we're talking about are most likely 18+ with lots of life experience otherwise.

[–] Spacehooks@reddthat.com 0 points 7 months ago (3 children)

It also looks like plug neutral is connected to plug live too? So its one single node to ground on the plug side?

are we sure the prompt was not "how to create a plug in north America for maximum damage?" 😄

[–] Canonical_Warlock@lemmy.dbzer0.com 0 points 7 months ago (1 children)

Except it wouldn't do any damage because there isn't anything running to the plug except for a single ground wire.

[–] Ilovethebomb@sh.itjust.works 0 points 7 months ago

Nah, maximum damage would be phase to earth alone, at least in terms of human safety.

This is a great way to wreck a socket though.

How to create a plug in North America to find an unlabelled breaker.

[–] floquant@lemmy.dbzer0.com 0 points 7 months ago* (last edited 7 months ago) (3 children)

There's no live wire in this diagram. There is a section of black wire that is labeled "live", but it's just connecting the ground wire to the top prong with no voltage applied. The unlabeled white wire shorts them together. If the white wire was cut, then the top prong would be ground.

This is just a fancy way to short neutral and ground.

[–] Damage@feddit.it 0 points 7 months ago (2 children)

Until you plug it in. Then it's a weird way to test your GFCI.

I was taught to call the neutral "common" cause neutral makes it sound safe.

[–] Canonical_Warlock@lemmy.dbzer0.com 0 points 7 months ago (6 children)

Typically in a US house it should be safe. Just assuming it is actually safe on the other hand is profoundly unsafe.

Forgot to add “safely” to the prompt.

[–] theneverfox@pawb.social 0 points 7 months ago (6 children)

No you won't... The "live" wire is just shorting neutral to ground. You'd need a second, far worse, problem for this to do anything

[–] FrederikNJS@lemmy.zip 0 points 7 months ago* (last edited 7 months ago)

Yeah... I tried to ask it in Danish, and this is what it came up with...

I've assembled a few plugs myself... And this certain isn't quite how I did it...

EDIT: This was actually Gemini 2.5 Pro... But it's not very "pro"
