I want to prepare my current electrical installation for the 3×25A (3-phase) grid connection to be made by Liander. I want the current distribution board to be inspected and, if necessary, renewed/replaced to be suitable for 3-phase. Liander will then perform the 1-phase → 3×25A conversion on the grid side. I also want a separate electrical line to be run to the kitchen for a new induction cooktop. The cooktop will have approximately 7.4 kW maximum connection power. I want the installation to be prepared to easily handle this power; with a suitable krachtgroep/kookgroep, protective devices, cable cross-section, and installation of the connection point in the kitchen. If possible, I prefer it to be prepared in a way that is suitable for 3-phase infrastructure and will not require recabling in the future if a similar power cooktop is replaced. The house currently has solar panels and an inverter. These will not be changed for now; the current PV connection must continue to work. The requested work in summary: * Preparation of the distribution board for 3×25A * Renewal of the current distribution board if necessary * Preparation of existing circuits to suit the new 3-phase system * Running a separate line for the approximately 7.4 kW induction cooktop * Preparation of a suitable krachtgroep/kookgroep and connection point * Protection of the current solar panel/inverter connection No intervention will be made to Liander's sealed grid side.
