For the installation of a charging station, a separate circuit in the fuse box is usually required. The number of circuits needed can depend on various factors, such as the power of the charging station and the available capacity in the fuse box.

In most cases, it is recommended to have a separate circuit for the charging station to ensure sufficient power availability and to safeguard the electrical system's safety. Having a separate circuit ensures that the load from the charging station does not interfere with other electrical devices or circuits in the home.

For an 11 kW charging station, a 3-phase connection is usually needed. This means that 3 circuits are required in the fuse box, each able to supply 16 Amps. The total power of the charging station is then 11 kW (3 x 16 A x 230 V). It may be necessary to make adjustments in the fuse box to accommodate these additional circuits.

It is important to consult a certified installer for the installation of a charging station and to discuss the specific requirements and possibilities for your situation. The installer can assess the electrical infrastructure and determine how many circuits are needed and what adjustments might be required in the fuse box.
