Quick Overview

Protection against shock and fire hazards during EV charging requires detection of AC and DC residual fault currents. This can be achieved by the use of dedicated RCDs, or by a combination of DC and/or AC residual current monitors with an A Type RCD or some other switching device. The following are the relevant IEC product standards covering protective devices for use in Mode 2, Mode 3 and Mode 4 EV charging.


A new type of RCD has emerged recently, known as an EV RCD. This can also detect AC and DC residual currents, but has been optimised for use in EV charging and is a lower cost alternative to a Type B RCD.  Type A EV RCCBs are designed specifically for individual EV chargers, where the model and make of the vehicle being charged is unknown. The EV RCCB will trip if the smooth dc residual current exceeds 6mA.
