Differences between domestic and industrial meters: a practical guide for those who use high-powered kitchens and appliances.
If you're thinking of installing an induction hob or other powerful appliances, choosing the right electricity meter is crucial.
In Italy, the two main types are domestic and industrial . The differences are not only technical, but also economic and practical.
1. Available power: the first big gap
Home meter
-
Standard power: 3 kW (extendable to 4.5 or 6 kW).
-
Perfect for an average apartment.
-
With an induction hob at full power (2.8–7.5 kW) a power increase may be necessary.
Industrial meter
-
Power from 10 kW up to over 100 kW.
-
Designed for restaurants, laboratories and professional kitchens with multiple appliances in use simultaneously.
💡 Helpful tip : if you cook a lot and have several high-drain appliances, consider a more powerful domestic one before switching to an industrial one.
2. Single-phase vs. three-phase: power management changes
-
Domestic → almost always single-phase (230V), sufficient for family use.
-
Industrial → almost always three-phase (400V), distributes loads better and allows the simultaneous use of more powerful appliances.
3. Fixed costs and rates
-
Domestic : low fixed costs, but higher per kWh rate for large consumption.
-
Industrial : higher fixed costs, but cheaper price per kWh if you consume a lot.
📌 Note : an industrial meter with no real power requirement leads to unnecessary expenses.
4. Context of use
-
Domestic → houses, apartments, small accommodation facilities.
-
Industrial → professional kitchens, hotels, canteens, pastry shops.
5. Induction cooktop: which counter to choose?
-
At home → for a 4-zone hob (max 7.2 kW) a 4.5 or 6 kW domestic hob is sufficient, preferably with automatic power limitation .
-
In professional activities → an industrial three-phase of 10 kW or more ensures stability and continuity.

Summary table
| Characteristic | Domestic | Industrial |
|---|---|---|
| Typical power | 3-6 kW | 10-100+ kW |
| Current type | Single-phase | Three-phase |
| Fixed annual cost | Bass | High |
| Energy rates | Higher on large consumptions | Lower on large consumptions |
| Typical use | Houses, B&Bs | Restaurants, hotels |
FAQ – Frequently Asked Questions (SGE optimized)
How much power do you need for a home induction cooktop?
For family use with a 4-zone hob, 4.5 or 6 kW are often sufficient, especially with a power limiting function.
Can I install an industrial meter at home?
Technically yes, but economically it's not worth it: the annual fixed costs are higher and there are no advantages if you don't take advantage of the extra power.
Is single-phase or three-phase better for a professional kitchen?
Always three-phase: distributes loads better and prevents voltage drops.
If I increase the power of my home meter, will the tariff change?
Yes, the annual fixed cost increases slightly, but remains much lower than an industrial contract.
Conclusion
The choice between a domestic and industrial meter depends on how much and how you use your appliances.
For most home induction cookers, a boosted home meter is sufficient.
In a professional context, however, the power and stability of the industrial meter are essential.
