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.

If you're asking a large language model for directions to wire electrical circuits I think you might have a bona fide mental disability and I'm not being funny or silly in any way.

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.

[–] Aeri@lemmy.world 3 points 6 days ago (1 children)

To be fair you are incredibly stupid if you ask this technology to render critical instructions and don't cross-reference it with any actual concrete information.

I do think that these companies should be held responsible for some negative consequences of their actions but people are going to be stupid and hurt themselves no matter what.

[–] Treczoks@lemmy.world 1 points 6 days ago

They trust something that is hailed to them as the ultimative super brain. They didn't get warned that the service is not a reliable source of information.

If you have to tell your customers not to stick kitchen knifes into children and not to attempt to stop the chainsaws' running chain with your hand, AI-providing services should at least be required to put thick warnings on their pages not to trust their lives. I just bought a kitchen-machine, and it has pages over pages of warnings in them for about things I would not have thought that people would need to be warned of...

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"

This device is useful for exercise. You will need to walk to the panel to flip the fuse every time you use it.

[–] yourgodlucifer@sh.itjust.works 13 points 1 week ago (1 children)

Actually it wouldn't do anything because you would not even be able to plug it in since the prongs are facing the wrong way and therefore would not fit into the socket.

[–] Ilovethebomb@sh.itjust.works 6 points 1 week ago

That's also a fair point, I'm not familiar with this particular plug, so didn't pick up on that right away.

[–] Modern_medicine_isnt@lemmy.world 12 points 1 week ago (1 children)

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

[–] Canonical_Warlock@lemmy.dbzer0.com 8 points 1 week ago (1 children)

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

[–] TwiddleTwaddle@lemmy.blahaj.zone 3 points 1 week ago (2 children)

Incorrect. The neutral wire is a current carrying conductor and will generally be just as "hot" as the hot wire.

[–] Ilovethebomb@sh.itjust.works 4 points 1 week ago (1 children)

Image being confidently incorrect in the comments of a confidently incorrect post.

Under normal circuit conditions, the only voltage present on Neutral would be whatever voltage loss is occurring between the load and the tie in point between neutral and earth.

[–] TwiddleTwaddle@lemmy.blahaj.zone 7 points 1 week ago (2 children)

Different circumstances are different. Neturals are current carrying conductors. Neutrals are also grounded (as in bonded to ground at the main panel). In the case of someone wiring a recepticle or making joints in a junction box without turning off the circuit, one side of the neutral will almost certainly become disconnected from its return path in that process. When doing electrical work you absolutely do not consider the N wire safe for this reason.

Sure, if you touch the N lug in a hot panel or the N side of a receptacle while everything's properly wired you won't get shocked, but nobody has any reason to touch the N conductor if you aren't working working on the circuit/box/panel. I'll admit my use of "generally" above isnt exactly appropriate when you consider that a home doesnt "generally" have someone working on the wiring. Similarly my "incorrect" at the comment above me is less than 100% accurate, but I maintain that in the case of actual electrical work being done (the only time this conversation matters) you can never consider N to be safe.

All circuits are hot. All guns are loaded. All knives are sharp.

I feel like federating this image is not in humanity's best interest

[–] hildegarde@lemmy.blahaj.zone 11 points 1 week ago (8 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.

[–] Steve@startrek.website 12 points 1 week ago

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

[–] i_am_not_a_robot@feddit.uk 12 points 1 week 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 10 points 1 week 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.

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 9 points 1 week ago (2 children)

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

It’s a plug, not an outlet. I made the same mistake because it’s such an astonishingly bad diagram.

Hot phase comes in from the prong, travels to the screw via black wire, then directly into ground.

Of course, it’s a moot point because you cannot plug this into a North American outlet, the prongs are in the wrong position.

[–] Ilovethebomb@sh.itjust.works 3 points 1 week ago (1 children)

There is no ground plug in this diagram, only phase and neutral. With the ground connected to phase.

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?" 😄

[–] Ilovethebomb@sh.itjust.works 8 points 1 week 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.

[–] J92@lemmy.world 7 points 1 week ago

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

Forgot to add “safely” to the prompt.

[–] theneverfox@pawb.social 6 points 1 week ago (2 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

[–] Ilovethebomb@sh.itjust.works 4 points 1 week ago (3 children)

but if the neutral was broken

Isn't that what I said though?

[–] __nobodynowhere@sh.itjust.works 3 points 1 week ago* (last edited 1 week ago) (1 children)

You may be doing what I initially did and mentally treating it as an outlet. The live prong on the displayed plug would be inserted into an real live outlet thus energizing both the neutral and ground. The dead short should quickly trip the breaker but maybe not before the outlet or plug is nice and crispified.

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!

[–] SketchySeaBeast@lemmy.ca 27 points 1 week ago (5 children)

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?

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.

Do you have dc in your plugs in usa or did the ai mess it up so much

[–] DacoTaco@lemmy.world 5 points 1 week ago

Even with dc this is fucked, + and - are shorted. Its fucked regardless

[–] LifeInMultipleChoice@lemmy.world 4 points 1 week ago* (last edited 1 week ago)

No, those plugs are 110-120v ac

Edit: assuming this is supposed to be a standard plug, which should have the prongs side by side not on top of each other.
