High-Pitched Sound from Fuse Box when 3.5 kW Air Conditioner is On in a 12.5 kW Apartment

I write 3.5 kW, I thought, just like everyone said that 3.5 kW is 3.5 kW

Of course, this is the cooling capacity of the device, not power consumption.

In the case of this "extended box", it will reduce the assembly time from 30 to 10 minutes

I would not say that inserting one bridge between the 1st and 4th fuse will shorten the assembly time, but let it be as it wants.

Not a "bridge", but two "bridges". Three phase and single phase. Of course, with a different power supply approach to the RCD.

Fair enough, but I still don't see the point

To tell the truth, will there be combs or cable bridges in the author's current switchgear (estimate that they pulled at the sleeves ) she is still suitable for d..y.

I apologize to everyone for misleading, but I'm just a fireman, and with electrics, all I have to do is disconnecting the battery in the car during an operation.

So now that it's clear that I misled everyone, does anyone have any idea about this noise???

The electrician won't be here until Wednesday, and I'd rather know what I don't have to think about.

Regarding this box, I will actually add what you wrote about and I will replace it.

And if the apartment / house is on fire? By the way, it's nice that you came to us, I will have a few questions about your procedures for sure. This time as a layman, of course :D

Electrician from the developer or yours?
If from the developer, refer to the law link , and more precisely on § 188. 2.

In the electrical installation in the apartment, separate circuits should be used: lighting, general purpose plug sockets, plug sockets in the bathroom, plug sockets for receiving devices in the kitchen and circuits for receivers requiring individual protection. "

Just to clarify, circuits that require individual protection, i.e. for devices over 2 kW: dishwasher, washing machine, oven (if not connected to the hob).
In 2008, in my apartment, I won a refund from the developer for connecting the circuit to the dishwasher in the kitchen.

Cheap Chinese crap.

The electrician will be mine now. I exchange it all from the wall including the box, a separate circuit to the kitchen I can't let go anymore, I'll just have to plug in somewhere.

The dishwasher is A +++ so it will not load this circuit very much?

Regarding this sound, after replacing everything, it should go away???

Enter the manufacturer's data since it is Chinese according to you, from what I know LVS is located in Toruń --> http://www.lvs-polska.pl/?cat=600

The class of the device is not only power consumption but also other parameters as in the case of a dishwasher, e.g. water consumption, etc. As in the 3.5kW air conditioner, this does not apply to the electrical power of this device ;)

Probably yes.

Go to the company information and you will understand everything.

I don't write anything about importing circuit breakers from China, I don't want to defend quick hands here, but Poland often produces worse crap than Asia

From what I know, A++ means energy efficiency - the device can consume up to 100kW, of which only 0.0001% will be wasted (e.g. heating wires), and the rest will be used in the correct way (example)

And should I replace everything from this box with this Eaton???

There are other manufacturers of electrical installation equipment, e.g. Hager or General Electric, these companies also produce good components.

This is the cooling power of the air conditioner, and the electric power consumption depends on the declared EER/COP ratio and varies depending on the manufacturer of the device.

As my colleagues have mentioned before, cheaper components can't be found anymore, so we know what the developer's guideline was.

Unfortunately, nothing from the range of this manufacturer is produced in Toruń, everything comes directly from you know where. Most of them are price, price and price again.

You're exaggerating the 90% a bit. Yes, some people fly at cost, but you can't generalize like that.

In fact, I exaggerated, but seeing probably dozens of apartments, I can practically count on the fingers of one hand well-designed and made installations.

A reliable developer is recognized not only by the high standard of finish, such as marble and gres tiles on the staircases, but also by the switchgear in the apartment.

The problem is that few buyers know about it and pay attention to it.

Thank you all for your help, and again sorry for this misrepresentation :)

Today there was an electrician by force I packed it in the car and in fact according to him it is also this contraption, tomorrow he is to take care of it and the rest of these gadgets too ;)

I'll let you know if it helped :)

Thanks again

Write, write, because my own ears are screaming...

Gentlemen, I declare that the problem has been solved today :D

The culprit was this gadget with the Test button ;)

Legrand is sitting now.

For now, only this is mentioned, and on Wednesday I will work with the rest, unfortunately I do not have the opportunity to run additional circuits, because I already have almost everything in the apartment covered, so I don't like to break the walls :/

Again, many thanks for your help

Nothing crazy, but something better

No worries, what would be better??? Because he installed it for me because he had it with him and shopping will be only on Wednesday, so what to take???
