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.
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
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.
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?
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.
What we really need is a USB-C-style reversible plug with data and variable voltage where neutral and phase never reverse and earth is always there.
Lacking that, I vote for Type N because it's small, polarised, and the pins are halfway-insulated. I don't like that the frame is symmetrical, so in the dark, the only way to tell which way to plug in is to feel the pins and the holes, same as USB-A. I reject all that hurt to step on.
There's a smaller version of type F that has the same frame as type N, just missing the middle pin, so it is reversible.
It has the same risk of reversing neutral and phase as type F, but (while I'm no expert) that has never been a problem for me.
Schuko (type F) is better than the UK plug. UK plug is huge, and schuko has same safety features, except the fuse, which is not needed if your houses would be build better.
Local fusing provides notable advantages, even without ring finals. In particular, one failed appliance doesn't necessarily take out the whole circuit, and lower draw appliances can be more closely fused (e.g. 3A) reducing available fault energy.
People get this wrong all the time. North America is 120V for the usual outlets, but what comes into your house is 240V split phase. You get 240V in places you want 240V, like electric stoves or clothes dryers.
Exception is apartments, especially those with elevators, which use three phase. Then you combine two legs to get 208V and your electric stove is kinda shitty.
The fuse offers per device protection, as well as per room/area.
E.g. you have a lamp that draws 1A. It's cable is rated for 3A. It has a malfunction and starts drawing 10A. This won't pop a breaker, but will overload the cable. Eventually it could catch fire from overheating. If it has a 3A slow blow fuse, it will kill the fuse before it kills the cable.
It also helps to isolate problems rapidly to 1 device.
They are extremely sturdy and safe, but they are too large and unwieldy. Infinitely better than the schuko plug though. No idea what kind of insane people thought a circular plug that has to be plugged in one direction a good idea. Always fun to spin around your plug hoping your prongs are lined up.
a circular plug that has to be plugged in one direction
Two directions since it's reversible, unlike Type G. Also the guides on the left and right help a lot with alignment. But none of these are perfect, really. If Type L was recessed and had shorter prongs then maybe...
Type G masterrace represent! The UK may have shit food, shit weather, shit people, shit politicians, shit culture and a shit economy but at least we've got good plugs...
Except when the unplugged cable lays prongs-up and you stab your foot by stepping on it. E and F are clearly superior. The switch on the socket will not convince me otherwise.
We don’t have shit food, you can buy all kinds of food here.
We don’t have shit weather, it depends what you like. I imagine rain is good for a lot of things and species.
Everywhere has shit people, but far more good people than shit people. It’s just shit people are more news worthy.
We do have shit politicians though but where doesn’t. Particularly when it comes to the working class or Palestine.
We don’t have a shit culture, you might be hanging around the wrong people. I’ve been to many Pro-Palestine protests in Manchester and we have all kinds of diverse people.
Not sure about the economy, that seems to be a global issue.
I’m not trying to be jingoistic about my country cause I’m really not. I will support any country the same as my own and although we do have issues with racism and stuff, it’s the minority of people.
