    Hello,
    gentlemen, the question may be trivial but I am green in the subject. How to connect this CD? I have 1-phase installation at home, no power. I understand that the upper scheme concerns me. Grounding to ground. Current (L) to BN and BK (or simply with BN and BK bridging). Analogously neutral (N) to BU and GY. It does not matter if I exchange L and N? I understand it well? Which one of my veins should I leave unconnected?

    The second thing - the electrician was to prepare the installation for me under pressure. At the moment when they let a vertical force on the cage, I think I can pull myself up to the flat and connect the board with strength. He gave the 4x4mm cable going to the plate. From what I now read to such a maneuver, we need a 4x5mm cable ... Anyone can tell me from this diagram whether it will be possible on this cable?

    Thanks in advance for your answer. Greetings!

    The installation diagram should be strictly followed and if you do not understand it, do not take on the connection. I omit the fact that the warranty must include an installer stamp and the fact that working on one phase is a weak idea and often impossible ...

    I ask out of curiosity, the electrician will be with me, but the very fact that he gave me 4 veins rather than worries me. I would like to advise you. Why is it a weak idea on one phase?

    On one phase, the board will want a current of 30A, and how is the fuse there? Ask the electrician for the number of wires, this is probably the installation (TN-C)

    But you still have other power-hungry devices ... washing machine, iron, boiler, coffee maker. There is probably another fuse for the sockets behind the meter.

    There is a separate fuse on the induction hob behind the meter, now I do not remember its power. The boiler is gone, but the rest will be there. I mean real opinions. I know that people in my block have induction and somehow it works. Can you tell me if I understand the connection scheme correctly?
    greetings

    It is not even known how the earthing in the installation is implemented (i.e. post # 2).

    but it is not that in the case of a personal installation, the user stays completely on the ice.

    So how is it?

    No warranty or responsibility of the store for hidden defects of the product. If the failure is not due to improper assembly, the first 12 months are subject to the presumption that the product defects found were there at the time of purchase. And in the next 12 months it is on the user's pregnancy to prove that they were at the time of purchase.

    Unfortunately, it's probably not like that.
    First of all, it is not a device with a plug to the outlet and the user's manual requires a connection by an authorized person. And the wrongly connected equipment falls immediately. Otherwise, it is not in accordance with the operating instructions. The second case, even with the warranty, the store will request the service's opinion about the causes of the failure and this will be obvious. No one in the dark will pay the equivalent for a damaged disc.
    The third issue, in the price of the equipment (which the store pays to the distributor) is the fee for the "guarantee fund".

    The boards are not connected to the Bosch service, only the authorized person and this is written in every connection instruction. The electrician's signature certifies not only the correct connection of the cable, but also the ability of the home installation to power the board.
    The repair service is able to show irrefutably that the board has been damaged due to improper connection - all you need to do is look at Electr. I do not understand what my friend's agitation is about.

    Even if that's what? Using it contrary to the instructions does not result in the loss of warranty if there is no causal relationship with the failure.

    Does this relationship exist, this is determined by the service expertise ... because it is not a seller or customer? And here you can always write that it is the fault of the customer's electrical installation, because before connecting the board was not checked.

FAQ

TL;DR: On single phase, expect about 30 A draw; "On one phase, the board will want a current of 30A." Follow the wiring diagram, use the correct bridges, and have an electrician confirm earthing and capacity before connecting. [Elektroda, Borutka, post #17030473]

Why it matters: This FAQ helps single‑phase homeowners connect a Bosch PVS651FC1E safely, choose the right cable, and avoid trips or warranty issues.

Quick Facts

Can I run a Bosch PVS651FC1E on a single‑phase 230 V supply?

Yes, if your installation can support it. Work on one phase is often a weak idea due to high current and limited headroom. Strictly follow the connection diagram. If you do not fully understand it, do not attempt the connection yourself. Have an authorized electrician handle the hookup and confirm installation suitability. [Elektroda, Borutka, post #17030305]

What breaker rating should I expect for single‑phase operation?

Plan for about 30 A demand from the hob on one phase. If your main or branch protection is 25 A, expect trips at high power. This is before adding the rest of your home’s loads. Ask an electrician to validate conductor sizing and select protective devices. [Elektroda, Borutka, post #17030473]

How do I bridge L and N for a 1‑phase connection on this Bosch hob?

Follow the device’s wiring diagram exactly. Use the supplied bridges to link the L terminals together and the N terminals together. Connect PE to the earth terminal. Do not swap terminals or improvise conductor colors. If anything in the diagram is unclear, stop and call an authorized electrician. [Elektroda, Borutka, post #17030305]

4x4 mm² vs 5x4 mm² cable: which should I use for the hob?

It depends on your earthing system and connection scheme. Confirm with your electrician how earthing is implemented and how many conductors are required. The system type dictates whether four or five conductors are appropriate. Do not guess the cable based on assumptions. [Elektroda, Borutka, post #17030473]

Does swapping L and N matter on an induction hob?

Yes. Connect L to the L‑marked terminals and N to N as labeled. Swapping violates the wiring diagram and risks damage or loss of guarantee. Always follow the device’s connection schema or call an authorized installer. [Elektroda, Borutka, post #17030305]

Do I need an electrician’s stamp or signature for warranty protection?

Yes. The installation should be performed by an authorized person, and documentation is expected. Without a pro’s confirmation, you risk losing manufacturer guarantee rights. Keep the installer’s stamp or signed proof with your purchase documents. [Elektroda, Borutka, post #17030305]

How will service know if the hob was wired incorrectly?

Service can identify faults caused by incorrect connection by inspecting the electronics. Miswiring leaves clear traces, and claims can be denied. "The electrician's signature certifies not only the correct connection, but also the ability of the home installation to power the board." [Elektroda, Borutka, post #17374686]

With a 25 A main, will the PVS651FC1E trip my supply?

It can. The hob may draw around 30 A on single phase at full power. If your main protection is 25 A, trips are likely when cooking at high settings. Reduce simultaneous loads or have an electrician propose upgrades. [Elektroda, Borutka, post #17030473]

What should I check about earthing (TN‑C vs TN‑S) before connecting?

Verify your earthing method first. Without this, you cannot choose the correct cable or connection scheme safely. Do not connect the hob until an electrician confirms how protective grounding is implemented in your flat. [Elektroda, Borutka, post #17030619]

Do I need a dedicated circuit for the induction hob?

A dedicated breaker helps ensure stable operation and simplifies protection. In this thread, the OP confirms a separate fuse behind the meter for the hob. Isolate the hob from socket circuits to minimize nuisance trips. [Elektroda, patrykk782, post #17030570]

Which conductor must never be left unconnected?

Never leave the protective earth unconnected. Connect the PE to the earth terminal exactly as shown on the diagram. If your cable does not provide proper earthing, stop and have an electrician adapt the installation. [Elektroda, Borutka, post #17030305]

How do I check if my installation can power the hob? (3‑step How‑To)

  1. Confirm the earthing system and conductor count with your electrician.
  2. Check breaker ratings; on single phase, the hob can draw around 30 A.
  3. If anything is unclear, do not connect; have an electrician perform the installation. [Elektroda, Borutka, post #17030473]

What happens if I wire it incorrectly or use the wrong scheme?

Miswiring can immediately damage the hob and nullify manufacturer guarantee rights. Stores often ask service for a cause assessment. If service attributes the failure to installation, you bear the repair or replacement cost. Keep proper installation proof to avoid disputes. [Elektroda, Borutka, post #17374517]

Who handles warranty issues: Bosch or the store?

The store supports statutory defect claims, while manufacturer guarantees are separate. The guarantee requires expert installation, but it does not cancel your statutory rights. Keep all documents and installation proof for either route. [Elektroda, Anonymous, post #17374555]

Should I avoid running other appliances while cooking on single phase?

Yes. High‑demand appliances add load and can trip protections when combined with the hob’s draw. Plan usage to avoid overlapping peaks with devices like washers or irons. This reduces nuisance trips and improves reliability. [Elektroda, Borutka, post #17030547]
