    Does the RCD need to power the car charger?
    Yes, per regulation 722.531.3, an RCD (30mA maximum) is required to power the onboard charger, and the RCD should disconnect all live conductors, including neutral. Therefore, to comply with regulations, unipolar RCBOs should not be used in this application.

    Some car charger manufacturers quote RDC-DD, what is this?
    RDC-DD stands for "Residual DC Current - Disconnecting Device". It is a specialized device, often integrated into car charging equipment, used to monitor and, if necessary, disconnect if any DC problems arise on the AC side of the unit. This is crucial as it affects the operation of the RCD and ensures additional safety measures for the car's charging system.

    If the car charger does not have RDC-DD, what type of RCD is needed?If there is no RDC-DD in the car charger, a Type B RCD is needed to power the car charger.  Type B RCDs are able to detect DC faults, ensure continued operation and disconnect when necessary, providing the necessary protection for the vehicle charging system.

     If the car charger has an RCD-DD that can detect and disconnect any DC problem above 6mA, what type of RCD should be used?
     In this case, a Type A RCD can be used as it can operate efficiently at current levels up to 6mA DC. However, it is worth noting that above 6mA, Type A devices may be affected and may go blind and stop functioning. Despite this, Type A RCDs are widely used and cost-effective, making them the first choice. It is worth mentioning that most car charger manufacturers have now added 6mA RDC-DD to their products to further support the use of Type A RCDs.

    RCD series:
    In some cases, individuals may choose to have an on-board charger supplied from an existing installation, possibly installed as a backup from a consumer unit. If there is not enough space for the new Type A RCD, consider installing it close to the car charger.

    Although Type A RCDs are not affected by DC currents up to 6mA, it is important to consider the time frame over which the RCD was initially installed in consumer equipment. If it was installed recently, it may be an AC type RCD. In this case, the RCD may also be powering other circuits in the house, which may be affected by any direct current from the car or may cause blindness. This can result in a lack of residual current protection for these other circuits, leading to potentially serious consequences. Therefore, careful consideration and evaluation of existing RCDs and their compatibility with on-board charger installations is critical to ensuring the overall safety and functionality of the electrical system.
