    The total leakage current of all the electrical equipment in the installation must be taken into account. The leakage current of CUE in normal operation can be seen in the electrical data section. During startup and in asymmetrical supply systems, the leakage current can be higher than normal and may cause the ELCB/RCD to trip.
