Bosch PIE611F17E Induction Hob 7kW: Upgrading Connection Capacity from 5kW, 1-Phase to 3-Phase

Question

Hello I am getting ready to buy a Bosch PIE 611F17E induction hob with a power of 7 kW. I was looking at my tauron contract and it says: Connection group - V Pre-meter protection 25 A. Measuring system - 1-phase Total connected load 5 kW My switchboard is ETI IP40 AC400V There are 5 current rose...

You need a 3-phase system to power this board, 1 phase won't drag you to treasures.
The fact that I write this on the switchboard only means that it is adapted to work with a voltage of 400V. You need to increase the connection power and specially pull up the 3 phases to your home.
Then, separate everything and make a separate circuit only for the induction plate with a 5x4mm or 5x6mm cable and protect with a 25A fuse

The board specification states that the board is 220-240V.

Anonymous · Answer

As you write 220-240 power supply, this gives a nominal load of 30.5 A You would have to have a 3f power supply with 40A protection and then power the board, e.g. from the L1 phase and nothing more, and distribute the rest of the circuits symmetrically to the other phases

Thank you for your answer.

I am weak from electricity, I understand that it is possible to connect to 1 phase?
When does the board consume 7kW? It is enough that all 4 fields will be turned on, or when I will only set all fields to maximum power?

Anonymous · Answer

Yes, as long as the power line is there 3 phase a security min. 40A What does it mean, a block or a single-family house All fields at max. power.

Why are you giving up and confusing the user who asks the question, since the power supply voltage is the only parameter for you? You behave like vendors in well-known supermarkets, telling people to buy farmazons - that the board is suitable for 230V installations. Yes, it is suitable, but not in Polish conditions. Nobody mentions it ...

Currently not. The miniature circuit breaker B16 has a nominal operating current of 16A, which is approximately 3600 watts of power. Approximately because: POWER = voltage * current. The value of the mains voltage varies with time. Overcurrent protection, popular circuit breakers, so-called esy has two triggers - short circuit and overload. In this particular single-phase case, we are interested in the overload release, which has a standard value of k = 1.13 ... 1.45. The trigger curve is not flat The closer to the limit value, the faster the protection will work. You can easily find such a characteristic. Returning to the merits, for a short while the protection will withstand a power of about 5350 watts. In all this, other devices in the installation and cables that have been used in the installation should be taken into account. It comes out without much counting that the current at the protection limit can reach about 25A. And where next?

Colleague Łukasz-O, no one makes water from the brain to anyone, since the specification clearly states the voltage of 220-240V, on what basis can we conclude that the board can work at 400V. The nameplate would dispel any doubts.

What does it mean, a block or a single-family house It is a block. What steps should I take in order to connect this disc? What does the labor look like in order to have 3 phases, there is a lot of forging in the apartment? I have a switchboard with fuses in my apartment and there is a whole installation downstairs in the cage from which I can read the electricity consumption.

pol102 · Answer

Without a site visit? It depends on what is connected (what wire) to the measuring system (meter) and what wire is connected from the measuring system to the switchgear in the apartment.

marek majchrzak · Answer

A: 1 There is a possibility. A: 2 According to the specification, this is Connected load (total) 7200 W, ie at maximum load. However, in your single-phase home, cooking dinner is the same as candlelight.

Łukasz-O · Answer

What specification? You mean the seller, what does the seller write on the website? Paste the link to the manufacturer's instructions. Then we can talk.

fixer45 · Answer

Tomorrow I will call the electrician who dealt with it and I will ask about these wires and what he will say about connecting the induction hob.

Anonymous · Answer

Has anyone written on this topic that the board is rated for 400V? Why did you paste this link? A colleague wrote to you that the voltage is not the only parameter. You're doing brain water buddy. If you have no idea about electricity, ask only questions on the forum - do not write in the affirmative and do not argue.

niewolno2 · Answer

My friend Bronek22 who talks about connecting a 7kW board to an installation with a connection power of 5kW, the author clearly asks what to do with it.

fixer45 · Answer

I have one more question 5kW is the maximum power that can be obtained on 1 phase?

Anonymous · Answer

A site visit is not needed Measuring system - 1-phase So from the meter to the apartment goes a three-wire cable and you need five and no one will allow you to rake the staircase (This is a new building from 2013) In this arrangement, the Kol. Plate cannot be used Yes

Łukasz-O · Answer

Thank you for the link. I just sent a request to the company to confirm this nonsense. As soon as I get a reply, I will share with you

fixer45 · Answer

On Monday, I call an electrician and I will make sure that it is a 3-wire cable.

And a hob with a power of about 3.7 kW would be able to connect to the 1st phase without any problems? The only question is whether such an album will not be too weak?

On the euro agd website, they write such stupid things:

"The voltage value in the electrical installation required for connection and proper operation of a given device - given in volts (V). Depending on the type of household appliances, they can be powered by alternating current with a voltage of 230 V or 400 V. The device with a supply voltage of 230 V can be connected to standard electrical socket, no special, durable installation is required The supply voltage of 400 V means that the device must be connected to a suitable, separate electrical system, so-called three-phase. "

One of the other things is important, according to them, the hob with a power of 7 kW and a voltage of 230 v can be connected to 1 phase, since you can have a maximum of 5 kW per phase ... In total, you can connect but use one field ..

Total connected load 5 kW

My friend Bronek22 what's the problem?

Łukasz-O · Answer

The problem is that you can forget about cooking. It's like that in a nutshell, without delving into the technical aspects of the installation.

niewolno2 · Answer

It is logical that you do not connect a 7kW board to a 5kW installation and I do not know on what basis my colleague Bronek22 accuses me of saying that you can connect a 7kW board to a 5kW installation. It is known that if the disc will not be used with full power, one phase will handle this disc, but if we turn on all the fields, it may not be interesting.

As far as I know, you can programmatically limit the power on this 7kW board. Buddy, I felt too weak - power is the power you need to cook. The woman was asked how much she wanted to get in the kitchen. They probably lied about it. If you connect to 400V, the plate will burn. Buddy - is it a cable with a plug, just like the oven? They didn't misspell, just you didn't move your head. Voltage 400V In the manual, it is an idiomatic phrase - specifying not voltage but the Polish 3-phase network. The instructions are not for you - but for the electrician. Like the drug contraindication leaflet - it is for the doctor. Buddy - elementary knowledge in the 21st century. Without this CD. If you turn on the 3600W oven, there can be problems with the washing machine at the same time. That's why you need to know something - do not wriggle out that you are weak with electricity.

niewolno2 · Answer

My friend Luke-O In such a system, lead me out of the mistake and indicate where, as you say, I cover my tracks.

Anonymous · Answer

Yes 230Vx16A = 3680W But this is at the limit of your installation possibilities, because if the voltage in the network increases with full control of the board (which is possible and acceptable) then protection B16 should operate. 25A-16A = 9A 9Ax230V = 2070W At full power of the board, 2kW of nominal power is left for the other receivers. You can use priority relays in the washing machine / dishwasher circuits I wish you good luck but I do not believe in miracles (rather 3 veins)

freebsd · Answer

Buddy Fixer45, according to the assembly instructions of your plate, you can connect it to one phase (L + N) or to two phases (L1 + L2 + N). For the latter option, you need a three-phase power supply. In the new block, the cables from the box with a meter to your home probably run along a technical plumb line, so any forging could be limited to the walls of your home. It is also possible that someone thought before and you have laid the cables for three-phase installation.
When you connect the hob to one phase, you can set the hob's maximum power (basic settings, parameter c7). Then the total power of the cooking zones will not exceed the set limit. This may mean that e.g. only one field will be able to work with maximum power (e.g. boiling a pot of water), and other fields at the same time will be able to work with low power (e.g. supporting cooking).

marek majchrzak · Answer

The only thing left is signing a new contract, allocating power, replacing the meter ... a bit of breaking up and modernizing the network at home and then it will go downhill.

Gregory_bg · Answer

Looking at the manufacturer's description, the device is powered by 230V and, as it happens in marketing manuals, nothing about the power scheme. Make sure about the power supply for this board or if necessary change the disc, the choice is yours
