    RCD Query

    Hopefully an easy query. Having great problems isolating RCD tripping. Happens only occasionally, say once a week. If I put fridge and electric water heater on their own plug in RCD plug would that plug trip first (if the appliance was faulty) or would the fusebox RCD, or would they trip...
