Whether 3x25A is sufficient for a charging station depends on various factors, such as the charging capacity of the station and the total electricity consumption in your home.

In the Netherlands, most households have a standard connection of 3x25A. This means that the maximum current you can use simultaneously is limited to 25A per phase.

When choosing a charging station, it is important to consider the maximum charging capacity that the station can deliver. Most home charging stations have a capacity of 3.7 kW (16A), 7.4 kW (32A), or 11 kW (48A).

If you want to install a charging station with a capacity of 3.7 kW or 7.4 kW, a 3x25A connection is sufficient. These charging stations can operate within the maximum current limit of 25A per phase.

For a charging station with a capacity of 11 kW, a connection of 3x25A is sufficient. A heavier connection of 3x32A is not necessary for this.

It is important to consult with a certified installer or the grid operator to assess the specific situation in your home. They can advise you on the required connection and any necessary adjustments needed for installing a charging station with the desired capacity.
