    UK Rcd tripping

    Hi I was called to a job where the rcd was tripping after a power cut. I have tested the circuits connected to it and all ok. I have tried turning the consumer unit off and on but rcd stays on. Would a power surge when power is re-energize cause this. Any suggestions would be helpful. Thanks Steve
