Induction Cooker & Oven Power Requirements: 10.7kW, 5x4mm2 Cord - 13kW Contract, 20A Protection

Question

Hello, I have a 13kw construction electricity contract in my house Power cord 5x10mm2 I plan to use an electric cooker with an induction hob + an oven with a power of 10.7kW, the power cord for the cooker was 5x4mm2 I have 20A protection in front of the building. The question is what security...

retrofood · Answer

Exactly what you have in the user manual. It's worth reading it.

Well, when I buy such a cooker, I will read it, at the moment I do not have it, so maybe someone has and has read it? I am finishing the installation in the house made according to the scheme from the project, I wanted to choose the security for the stove and install it nicely to have a finished cabinet.
On the Electrolux website it states: 2x35, 3x20, 3x35, 50 fuse required
http://www.electrolux.pl/Products/Gotowanie/Kuchnie/Kuchnie/EKI54500OX
Should it be read like this: for 3 phases full power is a 3x35 fuse or the possibility of connecting 3 phases for low power and then a 3x20 fuse?
Do we choose the oven power by the type of connection?

Buddy, you're not securing the stove. You secure the wires in the wall. But if you pull too much from the net, the pre-count will fly out. Sure induction hob (2 phases) 7.2 kW + 3.5 kW oven. What protection is 3 x B16, i.e. 3.5kW per phase in this circuit. The hob is not a heater and the average power is not 10.7 kW but less. At 13kW they give a pre-meter 25A, which gives a maximum power of 16.5kW. If there is a S-ka 25A, it will not fly out for some time 20% more. This adds up to ~ 20kW for some time. For a family without machines, this is sufficient.

Thank you for your answer, I have a 3x20A protection written in the contract, it has no characteristics and I do not know whether: for example, I assume a C20A protection, whether it will work sooner than the pre-meter protection. Please advice

But why is the contract for construction electricity? What type of pre-metering protections?

belineaenter · Answer

The house is unfinished and unclaimed, therefore the construction electricity I know only what I have in the contract with Tauron that 3x20A according to the 5th group. On Monday I will call Tauron and find out more about this pre-meter protection.

elpapiotr · Answer

The acceptance report (by ZE) states which protection has been installed. Besides, the technical conditions for connection also include the type and size of these protections.

belineaenter · Answer

I checked in the protocol there are meter data and seals as well as the size of the protection 3x20A and nothing else. I have not found the conditions yet, I will look for tomorrow, I will write what and how

mar_cik · Answer

Most ZE 25A pre-meter protections range from 14kW, 32A from 17kW. The 25A protection in the summer may not allow the consumption of even 20A. For a single-family house, 25A in front of the meter is the subsistence level. Normality starts at 32A.

It is me who will beat you with my RWE I have 12.5kW and 3x25A protection.

belineaenter · Answer

Ok, I looked in the box and there are Gg20A fuses. If it burns out, can I replace it myself? There are no seals on them?

Akrzy74 · Answer

Since you saw the gG20 print on the inserts, these seals are probably not there anymore ... Pre-meter protections should be sealed.
