An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

UK kettles boil faster than North American ones because they are plugged into 240v lines instead of 120v lines. But IIUC, you can pull the same amount of amps from either line. Why can't we make kettles boil just as fast no matter where they are plugged in, by pulling more amps? I guess it's the inherent resistance of the heating coil being the same? Can't we trade something off, use more coils, "plug it in twice," nothing??
I'm seeing that average UK socket circuits are 32A, which is nuts, I'm jealous. So that's it right there, 32A (I know (or hope) the kettle isn't pulling 32A) * 240v is a ridiculous amount of power, obviously more than any kettle would ever pull in a million years. My heat pumps and dryer are the only thing on the double breakers pulling 30A. Couldn't imagine a teakettle.
That's the max you can draw from the mains, not the single socket capacity. Sockets are wired to circuits at 13A. If you want to put a heavy duty appliance like an oven or induction hob, you put them in separate circuits with higher Amperage. Same for home EV chargers.
This is a great video about the topic. https://youtu.be/INZybkX8tLI
I FUCKING KNEW IT WOULD A TECHNOLOGY CONNECTIONS VIDEO. YOU CAN'T FOOL ME, LEMMY.
As soon as I started reading your comment I remembered the fused outlets of Britania. And as soon as I saw the YouTube link, I knew it was the same Tech Connections video that taught me it. I watched a video on British kettles despite being an American who drinks drip coffee.
