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

No, not at full power: with a 1-phase 5 kW connection and B16 cooker protection, a 7 kW hob will be at or beyond the limits of the installation, so you need to increase the connection capacity and, in practice, get a 3-phase supply if you want to use it normally [#14135404][#14135648] The AC400V marking on the switchboard only means the board is adapted to work with 400 V; it does not prove that your apartment already has 3 phases [#14135404] According to the assembly instructions cited in the thread, this Bosch hob can be connected either to one phase (L+N) or to two phases (L1+L2+N), and the latter requires a three-phase supply [#14135657] If you keep it on one phase, the hob can be power-limited in its settings, but the total power of the zones will not exceed the set limit, so you may only be able to use one zone at maximum while the others stay low [#14135657][#14135648] Before applying, have an electrician check the cable from the meter to the apartment, because in a new building there may already be a route for three-phase wiring, or there may only be a 3-wire feed that would need replacing [#14135580][#14135610]
