Regarding the RCCB i need to know the maximum Length to sense the Earth leakage I doubled Check the Virigex and Torriods the meaxmuim length is 15 Meters Please advice me regarding the RCCB


As recommended in the technical guide for RCD's,If long cables are installed downstream of the earth leakage protection devices, it may be necessary to take the natural capacitance formed by the cable/earth pair into account when selecting the RCD sensitivity to avoid Nuisance tripping (order of magnitude: at 230 V, approximately 1.5 mA for 100 m).
