When people are way too smug about their wrong answer.

Posting guidelines.

All posts in this community have come from elsewhere, it is not original content, the poster in this community is not OP. The person who posts in this community isn’t necessarily endorsing whatever the post is talking about and they are not looking to argue with you about the content in the post.

You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations. It becomes an argument as soon as someone becomes aggressive, nasty, insulting or just plain unpleasant. Report argumentative comments, then ignore them.

There is currently no rule about how recent a post needs to be because the community is about the comeback part, not the topic.

Rules:

• Be civil and remember the human.

• No trolling, insults or name calling. Swearing in general is fine, but not to insult someone.

• No bigotry of any kind, including homophobia, transphobia, sexism and racism.

• You are welcome to discuss and debate any topic but arguments are not welcome here. I consider debate/discussions to be civil; people with different opinions participating in respectful conversations.

• Try not to get too political. A lot of these posts will involve politics, but this isn’t the place for political arguments.

• Participate in good faith - don’t be aggressive and don’t argue for arguements sake.

• Mark NSFW posts if they contain nudity.

• Satire is allowed but please start the post title with [satire] so other users can filter it out if they’d like.

Please report comments that break site or community rules to the mods. If you break the rules you’ll receive one warning before being banned from this community.

This community follows the rules of the lemmy.world instance and the lemmy.org code of conduct. I’ve summarised them here:

  1. Be civil, remember the human.
  2. No insulting or harassing other members. That includes name calling.
  3. Respect differences of opinion. Civil discussion/debate is fine, arguing is not. Criticise ideas, not people.
  4. Keep unrequested/unstructured critique to a minimum.
  5. Remember we have all chosen to be here voluntarily. Respect the spent time and effort people have spent creating posts in order to share something they find amusing with you.
  6. Swearing in general is fine, swearing to insult another commenter isn’t.
  7. No racism, sexism, homophobia, transphobia, xenophobia or any other type of bigotry.
  8. No incitement of violence or promotion of violent ideologies.

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.

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!

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 1 points 1 week 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 14 points 1 week 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 -2 points 1 week 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.

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

[–] 30p87@feddit.org -3 points 1 week 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.

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 1 points 1 week ago* (last edited 1 week ago) (1 children)

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

Edit: Because this will trip the circuit breaker. It's a short y'all.

[–] Ilovethebomb@sh.itjust.works 8 points 1 week ago (1 children)

And the neutral is unbroken.

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

[–] Speculater@lemmy.world 3 points 1 week 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.
