Over the past years, we have seen a clear trend of using RCD Type A and RDC-DD for home charging applications. Some EV charger manufacturers declare built-in type-A 30 mA and DC 6 mA residual current protection at their EV chargers. It is nice to have built-in type-A 30mA protection at EV chargers as back-up protective measures of the external type-A 30mA RCDs, but the external type-A 30mA RCDs shall not be removed.
How to select 6 mA DC RCM for mode-3 EV charging points
More >
There are mainly three types of 6 mA DC RCM (RDC-MD) in the market. We have noticed built-in 6 mA DC RCM at a mode-3 EV charging controller is favored by most of professional EV charging point manufacturers worldwide.
Is an external type-A 30mA RCD still needed, when there is built-in type-A 30mA and DC 6 mA protection at an EV charger?
EV  CHARGING SAFETY
For mode-2 and mode-3 charging, Bituo offers a wide range of products that facilites cost-effective protection against fault currents of AC 30 mA and DC 6 mA. 
Among applications where smooth DC residual current protection is needed, we think EV charging is the one most urgently calling for high-performance and affordable protection devices. Therefore, our team decide to step up to promote IEC 62955 related products in the IEC market, aiming to speed up the protectiong upgrading for mode-2 and mode-3 charging.
