Got a new induction hob delivered and wondering where the plug goes? Induction hobs do not come with a standard plug — they connect directly to a terminal block via a dedicated circuit with a 32A breaker. This is not a job for an extension lead from the cupboard. If the wiring is old or there is no dedicated line, connecting without an electrician can end with a tripped breaker or a melted socket. We work across Warsaw — from Praga Poludnie to Wola.
How much does the connection cost and what affects the price
The cost of connecting an induction hob depends on the state of the electrical wiring in your flat. If a dedicated line with a 3×6 mm² cable and a 32A breaker is already in place, the technician will wire the hob to the terminal block in about an hour to ninety minutes. If there is no dedicated line, a new cable needs to be run from the consumer unit, and a breaker plus an RCD must be installed — that takes longer and costs more. Basic fixings are included in the service price. Additional materials (cable, breaker, conduit) are charged separately as needed. Current prices are in the table below.

| Induction stove connection | 250 zł | 400 zł |
How the on-site connection works
- You send a photo of the consumer unit and the hob location — the technician assesses the scope and gives an approximate price.
- We agree on a time — usually a same-day or next-day visit.
- On site, the technician checks whether there is a dedicated 32A line, what cable is installed (3×6 mm² is needed for single-phase, 5×2.5 mm² for three-phase), and whether earthing and an RCD are present.
- If the line exists — the rear cover of the hob is removed and the conductors are connected to the terminal block according to the manufacturer’s diagram (single-phase or three-phase).
- If there is no dedicated line — a cable is run from the consumer unit to the installation point, a 32A breaker and a 40A/30mA RCD are fitted.
- Earthing is checked with a multimeter. Without earthing, the hob can give electric shocks through its casing.
- The hob is switched on and every cooking zone is tested. The RCD is trip-tested to confirm it responds to a simulated leakage.
- We show you how to use the timer, the child lock, and the Booster function.
Important: connecting an induction hob is high-power electrical work (up to 7.4 kW). Incorrect wiring can lead to overheated cables, a short circuit, or a fire. If you are unsure about the state of your wiring — call a professional.
Common mistakes when connecting an induction hob (and how to avoid them)
- Plugging the hob into a standard 16A socket — it is not rated for 7+ kW loads, and the contacts melt.
- Using a 3×2.5 mm² cable instead of 3×6 mm² — the wire overheats under load, creating a fire risk.
- Not installing a dedicated breaker — the induction hob trips the flat’s main breaker when several zones are on.
- Mixing up live, neutral, and earth on the terminal block — the hob will not switch on or will behave erratically.
- Wiring for three-phase in a single-phase supply (or vice versa) — the jumpers on the terminals are set incorrectly.
- Skipping the RCD — if current leaks to the casing there is no protection, risking electric shock.
- Not checking the earth connection — in older Warsaw buildings the earth wire may be disconnected or absent entirely.
- Not leaving a ventilation gap below the hob — the electronics overheat and the hob shuts down.
What to prepare before the technician arrives
- Photograph the consumer unit — the technician will see in advance whether there is space for a breaker and what cable is present.
- Find out whether your flat has a single-phase or three-phase supply — this is stated in your energy contract or on the meter.
- Clear access to the hob location and the consumer unit — the technician needs to work freely at both points.
- If the hob is being built into a worktop, the cut-out should already be done (connection is electrical work only).
- Have the hob manual ready — it contains the terminal wiring diagram (single-phase / three-phase).
- Check whether a dedicated line exists — a separate cable from the consumer unit to the hob. If not, let the technician know.
- Remove pots and utensils from the worktop so the technician can work unobstructed.
- Provide entry details: intercom code, parking information.
A real case from Warsaw
A client in the Praga Poludnie district was switching from a gas hob to induction. He bought a Bosch Series 6 with four zones, rated at 7.2 kW. During the inspection it turned out the flat had a single-phase supply, and an old aluminium 2×2.5 mm² cable ran from the consumer unit to the kitchen — no earth wire and a single 20A breaker for the entire kitchen circuit. Connecting an induction hob to that line was out of the question. The technician ran a new NYM 3×6 mm² copper cable from the consumer unit to the installation point, fitted a dedicated C32 breaker and a 40A/30mA RCD. He wired the hob in single-phase configuration — three live terminals bridged together, neutral and earth separate. After switching on, we tested every zone at full power, tried the Booster function, and confirmed the RCD tripped correctly. The job took about three hours. Takeaway: in buildings from before 2000, a new dedicated line is almost always needed — old wiring cannot handle induction-hob power levels.
Frequently asked questions
Can I plug an induction hob into a regular socket?
No. An induction hob draws up to 7.4 kW — a standard 16A socket (3.5 kW) will not cope. You need a dedicated line with a 32A breaker and a 3×6 mm² cable.
What is the difference between single-phase and three-phase connection?
In a single-phase supply the three live terminals are bridged together and connected to one phase. In three-phase, each terminal goes to its own phase. The diagram is in the hob manual.
Is an RCD mandatory?
Yes. An RCD protects against electric shock if current leaks to the casing. For an induction hob a 40A RCD with 30mA trip current is recommended.
Does any cookware work on induction?
No. You need cookware with a ferromagnetic base — it sticks to a magnet. Aluminium, copper, glass, and non-magnetic ceramic will not work on induction.
What is included in the connection price?
Labour, travel within Warsaw, basic fixings. Additional materials (cable, breaker, RCD, conduit) are charged separately as needed.
How long does the connection take?
If a dedicated line is already in place — about an hour to ninety minutes. If a new cable needs to be run from the consumer unit — three to four hours.
Do I need to disconnect the gas if I am switching to induction?
If the gas hob has been removed — yes, the gas pipe should be capped. That is done by the gas utility, not an electrician.
Who does the work
Induction hob connections are handled by technicians experienced in electrical installations across all flat types — from pre-war tenement buildings to new developments in Wilanow. We arrive with a multimeter, a full tool kit, and basic consumables. If cable or a breaker is needed, we discuss it beforehand. To book, call or message us — we reply within an hour.
