Oven Connection Power: Choosing an Extension Cord for a 3.3 kW Oven & Dishwasher Safely

Hi,

I need to buy a power strip with an oven switch - I know some people will say it is stupid and the oven should be connected directly to the mains. Unfortunately, it is not possible with us and the need to use an extension cord. And here is my question: what extension cord / strip to buy to be functional and safe?
Maximum load?
Cable length?
Conductor cross-section diameter?

Oven connected load 3.3 kW
A dishwasher would also be connected on the same strip.
Of course, both devices will not be turned on at the same time.

Thanks in advance.

I can assure you that using these devices alternately is only for a while. Each should have a separate circuit with separate protection. Why can't you install a permanent installation and only combine it with extension cords, which will take revenge in the long run.

Why do you need advice when you have already made your decision and are only waiting for applause? Unfortunately, there will be no applause.

Unfortunately, I am not the first owner of the apartment and that's how it was thought. Built-in kitchen, all built-in appliances. There are two sockets on the wall with a ceramic hob, oven and dishwasher. The hob is connected to one. Oven and dishwasher for a second.
This, unfortunately, has already taken its revenge, as the oven and dishwasher were plugged into rather poor quality power strips. At this point, the button on the strip does not work (whether it is on 0 or 1, the strip is on all the time).
Now I have to remove the oven because the socket is directly behind it and change the power strip connected to this socket to a new one and connect both devices to this strip. That is why I care about a solid strip.

Thanks for the advice. Another, if someone has, they will probably be useful.

I think you can talk more politely. In addition, I am not asking here how to install, but what extension cord / strip to choose in these circumstances.

But my friend is very polite, but firm. One extension cord has melted. In the event of a failure, the next one may be a fire. The electrical installation is not adapted to such receivers and cannot be connected in this way (about 5 kW on one extension cord!)

I do not know the concept of "first owner", but since it is so important, it is worth contacting him about a security related matter.

I wrote that I would not use both devices at the same time, and I hope that there are extension cords that can withstand, for example, 3.6 KW

As above, Christmas will come and you will want to bake and do the washing at the same time. Better to make sure and neat, but probably the tiles are already laid.

So I understand that, according to the gentlemen, the advice given by the lovers is not right?

So don't ask since you know better that the installation will work because you planned it and your only problem is the extension cord. Well, it's not like that, you're trying to break a thermometer instead of treating a fever.

It requires no comment.

Please don't get me wrong. I don't want to do this at all costs for security just to keep it working. If that were the case, I would go to the supermarket and buy an extension cord for a tenner and would not even enter this forum asking for advice.

There is only one thing I cannot understand: why everyone advises against connecting the oven to the mains via an extension cord. If the oven has a max. 3.3 kW power and the extension cord can lift 3.6 kW, what is the obstacle? I am not saying that what I am writing is the most sacred truth. I have seen such solutions in more than one house. This does not mean, of course, that this is the optimal and the safest solution. I am just asking for an argument why this connection cannot be made.

For today I'm going to turn off the fuse responsible for the oven and dishwasher, which also has a cooker hood, and not use the oven to solve this problem.
I hope it doesn't hurt to turn off the fuse?

3x1.5mm2 of course, and you will secure it all, of course, B20, echhh
the necessary minimum is 2.5mm2 and it's only for the oven.

As it is a receiver with an area of 2kW should be a SEPARATE circuit and not connected together with the dishwasher.
Why everyone advises against, well let's think what is written under CE - often a significant China Export - is worth as much as the cat cried.

Of course, you are at home 24 hours a day, and your woman will certainly understand what's going on, because according to she will simply turn me on when she has such a need, an example of which is the current strip.

But as already written, why cure when you can break a thermometer.

Okay. As I wrote above, let's leave the dishwasher - there will be another place for it to connect.
Let's stay by the oven. It cannot be connected with an extension cord with a max. load of 3.6 kW when the oven has a max. 3.3 kW?
I checked the oven instructions and the manufacturer writes there that the cable to the oven is 3 x 1.5 mm2. Why can't a skirting board with the same parameters be used?
I am also not talking about a Chinese cable, but a solid, good Polish product.

Because the strip has several sockets and it is possible to connect other receivers.

Buddy, there is such a thing as load capacity, although your oven has ~ 14.5A, however, the wires should guarantee safe power supply to the receivers.

I have enough of the explanation, you demand (not even that you want), you demand your idea.
So I ask why this topic was answered many times, and you want us to change our minds and ignore what for several years, teenagers and some and ten have learned and tested in practice.

Subject to be closed.

PS If the producer writes that you can heat with gasoline, will you listen to it too?

I do not ask for or require anything. I am only asking for a clear argument why it cannot be done this way. He does not get answers argued only like "no, because no, because this is how it is supposed to be and the end".

It's your installation, you can do it as you like, just remember that you are responsible for your own decisions.
On the other hand, the problem is that you demand an answer that goes far beyond the scope of one post, because it covers at least a few years of knowledge gained at school and several or several years of practice and gaining experience. So why don't you believe the words but demand a lecture? No one wants to write a book just for you to believe.

But I will try to tell you so that the dilettante understands.
If you have a car, it has a top speed. Let it be 160 km / h. Are you on every road and always driving at that speed? No, because speed also depends on other circumstances.
So why do you want to run your extension cord constantly at full capacity? Consider the circumstances.
Permanently built-in oven - you want to supply it with a makeshift.
The oven has a power of 3.3 kW - this is the limit capacity of the extension cord, but under what external conditions? - You do not know that. Not only that, you will have the extension cord hidden, invisible, without good cooling, because it is pressed somewhere in a hole and you will not have a chance to notice the beginning of its depletion! And at elevated temperatures, the aging phenomenon of the insulation develops rapidly! Also, do not forget about the heating of the contacts of the plug and socket, which is inevitable. Exposed metal always oxidizes and the oxides hinder conductivity. You will see the effect when the kitchen is on fire.

These are only minor elements of the answer, there would be a lot to write about, just remember that no reasonable person uses the equipment to the limit of its capabilities in the conditions of no control of its behavior!
It's a simple road to suicide.

I close the topic, because further discussion is pointless, since you asked for advice, you received it, and if you do not believe in it, see the first sentence of my answer.
