What is the best Power Outlet, and why?
-
it's a bad practice to design appliance in such a way to assume that neutral will have low voltage, because in case of neutral failure in three-phase circuit you can get full voltage there,
Who's using three phase in a setting where these types of plugs are used? In the US, at least, three phase circuits use very different receptacles and plugs.
The fact of the matter is that the switch has to be placed somewhere. And it's safer to place the switch between the load and the live wire, rather than between the load and the neutral wire. Designing a system where the live and neutral can easily be known makes it easier to do the safer thing.
wrote last edited by [email protected]you don't have to have three phase circuit to be affected by floating neutral in three-phase substation upstream. in some places in us there are 208v interphase three-phase circuits, which give 120v phase to neutral, which is distributed as a pair of wires as single-phase circuit. this is also normal way to deliver single-phase power in europe, as it's most efficient use of conductor. (from 400v three-phase circuits) in case more power is needed than single-phase circuit can deliver, three-phase circuit is installed
if there's switch on device, it's 2p1t meaning both phase and neutral are switched. if it's permanent, non-pluggable circuit, like lightning, it's okay if only phase is switched (neutral is connected permanently)

Can you plug C into F?
Yeah. You cant plug f into c because f is thicker by a bit but c goes into f.
-
It's not inset meaning that an improperly plugged in plug becomes a hazard.
bases of pins are insulated, like in type C/E/F
-

Not true, the pins are sleeved so if it is improperly plugged in, you still can't touch live parts.

Type E/F carries 16A/230V, and nowadays there are shutters included which only allow two pins to be inserted at once, not one but not the other. There's no standard as of which pin should be L1 and neutral anyway, nor it should matter, and fuses in british plugs are to accommodate ring circuits, which were introduced as a result of copper shortages (ie decades of tech debt)
Type B also does this now with the shutters.

Type B is objectively inferior. This is not anti-americanism either, Technology Connections has my back here. But it's not bad enough to replace three big countries worth of plugs and outlets. The only way to have a global standard would be something like Italy's plug orgy system where you can fit multiple different types but that would kinda defy the purpose.
So you say technology connections has your back but you didn't even say why it's inferior my first thought is you have no idea why. It just seems dumb posting that without any sorta proof.

These are the best anyway

why would you shove things into it's mouth?
Because it likes it.

Earth pin is a safety feature and a good one at that.
So is the shutter system. Blocking contacts unless a third is pushed in is great safety, particularly with kids.

F plugs are the only type I've ever seen in all of Scandinavia, Germany, Spain and The Czech Republic. Never in my life have I seen an E plug or anything resembling a variation of E+F combined in any way. Only F. I don't understand how you can say they "are not really a thing anymore".
You mean not a thing in the UK?
Went to Poland for a few days and encountered the type e plugs and I immediately hated them because they interfere with chargers and they weren't reversible.

Only if they're charged.
P.S.: since battery cells need to be disposed properly, they are now an 18+ purchase.

Type J is superior in every aspect.
- compact, you can fit 3 plugs into an outlet while Type F only fits one for example.
- robust.
- cannot reverse polarity.
- no fuse required as the law requires proper fuses in every electric installation with law enforced periodical checks.
- round pins that cannot puncture your skin if you step on them. It's hard to face the pins upwards anyway.
---------Compact in one dimension, but it is very long.
This makes it awkward in tight spaces compared to something like a UK plug. -
If the device wants the current to go in a certain direction
That's not how AC works
they use one with a slightly larger prong on one side,
That's not Ground, it's Neutral. Neutral is sometimes bonded to Ground, but they are fundamentally different things
- Yeah it's just a potential difference, not a one directional flow really
- No one said it's ground? The ground is on the third prong

For your USB power supply, mobile charger, LED table lamp, game console, etc., which doesn’t even have an earth connection, not so much. But your power board takes up twice the space of a European one with a row of slender unearthed sockets for such devices.
The British standard is still stuck in 1947, where the expected use cases were kettles, washing machines, pre-transistor radios using high-voltage thermionic valves, and the domestic labour-saving devices of the midcentury that needed to be earthed. That and the shortage of copper that led to British houses being wired with a ring main, and each plug having its own fuse, rather than separately fused circuits as elsewhere.

Fusing plugs is completely unnecessary. The only reason this is done in the UK is because of old janky circuits only used in the UK.
So still necessary in the UK

USB. Most things don’t need AC power. We can get rid of wall warts and create a universal standard by including USB C ports on AC plugs.
On my way to power my fridge and oven by usb-c!

And having your chargers look like clown shoes compared to the slender 2-pin chargers used in Europe, Australia and elsewhere is a small price to pay.
Do more kids really die of electrocution in, say, France or Germany than the UK?
