Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Why would they invented a plugs that's not grounded? (Type A and C)

I fucking hate it because my country's default plugs is type C. Caused me so much trouble in damaged electronics, shocked, and the effort to make a grounded line for each individual electronics myself.

[–] [email protected] 0 points 5 months ago

A is much less of a pain than C. At least in most cases the plug pinches into the outlet and stays in place.

I've used C while traveling for my charger and The weight of a few cords wants to drag that fucker out every time.

Also worth noting that A can come in the polarized (one plug slightly larger, fits one way) or non-polarised (doesn't matter) variety.

Remember, all this stuff started over a century ago. The main application was electric incandescent lights, which are fine to run with only two wires.

devices with double insulation don't need a ground connection

Does Finland use C outlets, though?

At least in the US, just about every outlet has a ground port (Type B), even if the device you're plugging in has only a 2-prong plug. I've only seen the Type A outlet in one really old building.

Lots of old houses in the US still have a bunch of the Type A outlet. My first apartment did for most outlets.

Now, what's really fun is Knob and Tube wiring, where the hot and neutral lines are separate wires. Which means they tended to be run in separate directions if it was convenient for the asshole from a century ago to run it that way.

Finland uses C and F, where F is for grounded and C is for laptop chargers and such that don't need grounding.

[–] [email protected] 0 points 5 months ago

Type c is commonly used in my country for small appliances as it can be used with type E and F plugs which are used everywhere

Your neutral should be bonded to ground anyway. If you have current on the neutral that needs the ground path, something is wrong.

All the house I wired had neutral bonded to ground wire at the panel.

[–] [email protected] 0 points 5 months ago

Hi, so should I just grounded the neutral wire from the fuse box (the one that goes from the pole into the house) instead of running a ground wire to each devices?

[–] [email protected] 0 points 5 months ago (2 children)

the non grounded plugs are usually only used on double isolated devices, like your phone charger.

double isolated basically means all the outputs are only referenced to each other and not to ground, so you won't get a shock by touching a usb plug, where you absolutely would if you touched live wire, where the reference is earth

Funny enough I got shocked by a USB port once because it was "grounded". I have my PC plugged into a fairly beefy power strip, and after getting zapped I figured out that the outlet the power strip plugged into was not grounded. So the power strip acted as a mediocre transformer, putting about 70v through the ground wire my PC was plugged into, then the grounded metal of the USB port.

Surprisingly didn't fry anything in my PC, even that USB port still works just fine. Went through and checked all my outlets were properly grounded after that, thankfully it was just the one I needed to fix.

my pc case shocked me when I touched it, not a huge shock like live wires but enough for you to feel a little pain (like static shock on winter day). My phone charger also shocked me the same way when i touched the metal part of the USB head.

[–] [email protected] 0 points 5 months ago (1 children)

yea PC power supplies do need the earth pin, but i'm surprised the usb also shocked you, maybe a faulty adapter?

[–] [email protected] 0 points 5 months ago

It's a $80 GAN charger from Ugreen and the C-to-C cable that came with my iPhone.

I would be a big sad chump if it's a faulty brick. But thanks, I'll find a way to troubleshoot that.
