Residual current circuit breakers (RCCBs)
This device is essentially a attached to it. So basically it will only break the circuit when there is a leakage current flowing to earth. The tripping time is such as to minimise the risk to human life.
RCCBs usually have a fault making and . This means that they can handle a fault of 1 kA on their own if it is a fault to earth.
Type B residual current device disconnects the power if the earth leakage current is detected as dangerous. If the earth leakage current is equal to or less than 10mA, then the Type B residual current devices would not trip because this current amount is not dangerous. The electric car will continue to get charging without any interruption. The Type B residual current devices will immediately trip the circuit and disconnect the power supply for higher currents. Like this, Type B residual current devices will protect the circuits from danger.
