Understanding the Role of Fuses in UK Plugs & Replacing them with Polish Plugs Safely

My friend still doesn't understand.
If the protection in the mentioned plug works, the device simply will not work.
How will it come

damage to the insulation of the device and a connection between the phase conductor and the earthed housing will be created

the circuit breaker on the circuit to which the device is connected will operate.
We talk / write all the time about connecting this receiver to a socket in Poland via an adapter.
There are still no regulations, and a colleague will not give them, i.e. ...

In Poland, such a test is provided for and this is the answer to the subject of device fuses in the device. If there is only one device fuse, the device should be short-circuit proof without the fuse. Thus, the device either has no metal grounded parts or has reinforced insulation to these components. Otherwise there should be two fuses. An example of using two fuses is a surge protector.

Why a fuse if the device is resistant?
Buddy, from today, before you write something, add the phrase "it seems to me".
A device that requires polarity should be connected permanently otherwise it is a bummer.
I have a surge protector with one fuse, the receiver also with one fuse on the mains side.

Quote:

Connecting an English device in Poland through an adapter causes the device to be improperly powered, because these devices are adapted to installations in Great Britain, where the position of the phase and neutral contact is standardized.

A colleague continues to write stupid things because nothing wrong will happen. Once again, I propose to buy the aforementioned devices or carefully study the photo posted by Paweł.

Loooong friend thought.
But to the point - if the fuse in the plug does not work, the circuit breaker for this socket will work.
Checked SWZ is OK.

What now ? What are we going to come up with?

What is the fuse for? The fuse protects against the effects of a short circuit. The device is not short-circuit proof, only short-circuit-proof without a fuse . Please read with understanding.

I have read several times and still do not understand:

I agree with this shit. The AV receiver may have one fuse, the surge protector is a bum.

But why? Can the receiver have one fuse and the surge protector already have two? The surge protector is to protect the receivers from overvoltage, there should be two varistors, not fuses.

WojcikW wrote:

Exactly. The circuit breaker around the socket will work and the fuse of the smaller value in the plug will not work. Why a fuse that won't work? Such a fuse is only a threat because it misleads the layman and turns out to be not only a layman.

It does not introduce any threat, it only protects against short-circuits in the receiver. The user does not have access to the "guts" of the device.

Maybe it's enough?

Let's summarize.
The author of the thread can of course replace the "British" plug with a "Polish" plug.
It can also use an adapter enabling connection to the socket used in the country.
If he has more such receivers, he can use a "British" extension cord / strip with a "Polish" plug.
I used this solution myself.

However, the posted rubbish that the short power cable of the receiver causes the tearing of the working cables from the terminals and discrediting the solution used for years, here in a professional forum there should not be a place, and certainly not in the section for beginners because it is not only stupid, but also harmful.
The author of this "revealing" theory is not aware what is the reason for just such dimensioning of veins.
And the point is just for the protective conductor to come out of the terminal last.
I will not explain why this is so, but I will mention that such a requirement was already included in the PBUE.
And please show me the plug from which the wires will not come out if the cable is too short.
So maybe instead of lengthening individual wires, a longer cable should be used?

Another false theory concerned the alleged legal prohibition of placing fuses in plugs, and the fact that (in Polish conditions) the plug fuse will be in the neutral circuit, if the socket is connected in accordance with Mr. B's instructions, it will be in phase on the right.
Well, there is no such prohibition required by law, and the plug inserted into the adapter inserted into the "Polish" socket with the phase on the right side will have phase on the track with the fuse, because this "adapter" forces the plug to be turned 180 degrees. And this friend WojcikW he did not deign to notice.
You do not have to worry about the selectivity of this plug-in circuit protection, buddy, because you are not right in this matter.

So gentlemen repairmen, forgive yourself in the future to make water from the brain of other people.

Are you asking, Staś, is it enough?
Of course it's enough, so I close the topic.
