The technical requirements depend on many factors, such as the power of the wallbox and the existing electrical installation in the building.

Here are some important technical requirements that generally need to be met.

• Power connection: A sufficient power supply is required to supply the wallbox with energy. In most cases, a high-voltage connection (400 V, 16 A or more) is required to provide the necessary charging power.

• Fuse and cable protection: The existing electrical system must be able to cope with the additional load of the wallbox. It may be necessary to extend the fuse and cable protection.

• Professional installation: The wallbox should be installed by a qualified electrical contractor to ensure correct wiring and compliance with applicable regulations.

• Residual current circuit breaker (RCD): A residual current device (RCD) is important to protect people from electrical accidents. The wallbox should be connected to its own RCD.

• Measurement in compliance with calibration law: If the wallbox is to be used for billing charging processes (e.g. in apartment buildings or commercial buildings), it must comply with calibration law and measure the charging processes accurately.

• Communication interfaces: Some wallboxes have communication interfaces such as LAN, WLAN or modem to enable connection to external systems for control, billing or access control.

• Installation location: The installation location of the wallbox should be easily accessible and comply with legal requirements, e.g. with regard to the minimum height above the ground and protection from the weather.
