Hello,
I have often had a cable with cheap power supplies that had a two-pin EU plug on it and a three-pin cold device connection on the other side.
Is this even legally allowed?
You could use the cable for a machine that absolutely must be grounded, and then the machine would not be grounded. For me, such a cable poses an increased safety risk.
Does anyone know anything about this?

Loading...Hey, I have the problem that sometimes/often after I turn on my distribution socket for the PC and setup the fuse blows. Can anyone help?
Hello, Is it possible to solve the following task with the calculator (Casio fx-991DE X CLASSWIZ)? Determine the zeros of the first and second derivatives of f(x) = x³ – 9x² + 24x + 2. Check whether the zeros are maxima, minima or inflection points.
I don't want to always use my phone for that. preferably energy-efficient I don't know anything about the alarm clock business
Hi, I bought a monitor for Christmas and have a question about using it. When I connect the monitor to my laptop and open a program on the monitor, it opens on the laptop, but I can't display the program/game on the monitor via the taskbar. Is there perhaps a keyboard shortcut or other solution?…

This depends on where you have the power supply and the corresponding plug. If you bought it from a dealer in Germany or the EU, that would be a violation of the conformity standard, that is the CE sign that is printed on the devices everywhere. You could claim the device, probably not sold and delivered.
In practice, there would be no danger in this power supply since there is a contact protection through the plastic housing. The PE-Pin is usually not connected. ABER: As you have noticed correctly, there is a risk of using the feed line on another device.
However, if you have ordered the device online directly from the Chinaman outside the EU, the following applies:
There, plug connections of the plug type D are often attached. They are actually widespread in India, South Africa and Lybia. Mostly without PE. Standard in these countries. Now you get the plugs in a Schuko socket, and then it’s getting dangerous. Or better said it is always dangerous but standard in the countries mentioned before.
This plug type is often confused with the euro plug, but no one, look at this picture:
Yes, a German dealer told him.
As long as I don’t see the cable all around, I don’t think so.
It makes me a little stubborn, because on the cable 3G is 0.5 mm2.
This has also surprised me to cut it up today and is really a 3G but the protective conductor is short cut off from the plug
I had actually expected a photo before and after it was cut open.
In this combination, plugs and sockets must not be assembled.
With a new device, this is a reason for complaint.
This feed line is disposed of so that it does not use anyone accidentally for a protective class 1 device.
It is safe on the power supply because it is protective insulated and does not need a protective conductor. Your objection is justified, however, because you could also use the cable for other devices that need to be grounded.
We know what to use it safely…
But Otto Normalconsumer therefore connects his PC because it is “so beautifully thin” and he can’t recognize a problem.
Such a cable must not exist
Your question is wrong here, your concerns are justified. Please write it to the Chinese who made this junk.
Danger well recognized!
The line cross section is also slightly thin.
Cold device cables are designed up to 10A MIT PROTECTION.
Please do not use, since the euro plug does not deliver both. This should not have been sold in this country. Cut the best and then dispose.
There are occasional such cold device cables without protective conductors, but they then have a contour plug (like the one on the hair dryer) and the corresponding cold device plug with only two holes that only fits in devices that do not need a protective conductor.
You can use any other (correctly manufactured) cold appliance cable with protective conductor.
If a device has such a faulty cable, I would have doubts about the device that it was attached to.
And in the case of power supplies, the first bid is anyway: you should not save on the power supply! Better spend a little more, but for that it is safe and reliable.
At the latest, if there is a greater damage due to a questionable power supply, you are annoyed by the “saving”.
Therefore, I would send back the chinacracker and buy something better.
Your objection is completely justified. Even with the power supply, this is a problem because you have AC voltage at the end of the day.
Especially for cheap power supplies, the CE seal does not stand for “Conformité Européenne”, or ‘European conformity’, but for ‘China Export’.
Funnyly, this is almost the same seal but “China Export” is not quite round, rather a clamp.
That’s nonsense. There are now protected-insulated devices, such as this power supply, to which not only a protective conductor cannot be connected, but also not allowed.
