For the installation of a charging station, a separate circuit in the meter cabinet is typically 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 meter cabinet.

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

For an 11 kW charging station, a 3-phase connection is usually necessary. This means that 3 circuits are needed in the meter cabinet, each capable of delivering 16 Amps. The total power of the charging station is then 11 kW (3 x 16 A x 230 V). Modifications might be needed in the meter cabinet 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 options for your situation. The installer can assess the electrical infrastructure and determine how many circuits are necessary and what modifications might be required in the meter cabinet.
