How to Safely Connect an Induction Hob: A DIY Guide

Induction hobs are increasingly popular in modern kitchens thanks to their efficiency, elegant design, and precision cooking. However, connecting an induction hob is not a trivial task: it requires minimal electrical skills and full awareness of safety regulations .

If you are thinking of installing it yourself, in this guide you will find all the fundamental steps for connecting the induction hob safely , starting from checking the electrical system .

1. Check the electrical system: is it suitable for induction?

Before connecting your induction hob, it's essential to ensure your electrical system is suitable. Induction hobs consume a lot of energy: they often require a power of at least 3.5 kW , but some models even exceed 7 kW .

✅ Preliminary checks:

• Check the contractual power of your meter (from 3 kW and above).

• Make sure that the electrical system is up to standard and equipped with a residual current device (RCD) .

• Check that there is a dedicated line for the hob, with a minimum cable cross-section of 4 mm² (for powers over 3.5 kW, 6 mm² is recommended).

• You need a 16A or 32A circuit breaker, depending on the model.

2. Prepare the tools and materials

To safely connect your induction hob you will need:

🧰 You will need:

• Insulated screwdriver

• Terminal block (if not integrated)

• Current tester

• Screw terminals (Wago or similar)

• Standard electrical cable (3 or 5 wires, depending on configuration)

• Piano Installation Manual

⚠️ Important: Always disconnect the main power before starting any work!

3. Connect the power cord to the hob

Most induction hobs have a rear terminal block with a connection diagram in the manual. The most common configurations are:

• Single phase (230V): L – N – PE

• Two-phase (230V+230V): L1 – L2 – PE

• Three-phase (400V): L1 – L2 – L3 – N – PE (for industrial systems)

Do this:

1. Identify the wires:

   • Brown/Black (Phase or L)

   • Blue (Neutral or N)

   • Yellow-Green (Earth or PE)

2. Connect the wires to the terminal block , carefully following the manufacturer's wiring diagram .

3. Securely fasten the cable into the tabletop's cable gland to avoid accidental pulls.

4. Check the grounding

The safety of an induction hob depends largely on its grounding . Without this connection, the risk of electrocution in the event of a fault is very high.

✅ Security check:

• Make sure the yellow-green wire is connected to the PE terminal.

• Check with a tester that the ground connection is present and effective.

5. Turn the power back on and test.

After completing the connection:

• Reactivate the electrical panel.

• Check if the hob turns on properly.

• Test with a suitable pan: the hob should detect its presence and start heating.

When is it best to call a professional?

If you're unfamiliar with electrical systems, it's highly recommended that you hire a qualified technician . While many models are suitable for DIY installation, safety and compliance with IEC regulations must be a top priority.

Conclusion: connecting an induction hob is possible, but care is required

Connecting an induction hob can be done independently only if you have a good understanding of electrical systems and follow all safety regulations . Ensuring that the induction electrical system is adequate and using compliant materials is essential to avoid accidents.

👉 Remember: induction hob safety starts with your electrical panel!
