Consumers units are now designed with nuisance tripping in mind. Either Fill the board with RCBO's (expensive but coming down in price) or 2 RCD's and the board split between them. Then if it trips then only half the house goes out and if designed properly you loose for instance the upstairs lighting circuit and the downstairs ring-main.
