i have changed my standard wired fuse box to split load with rcd.all my plugs,shower and garage are protected by rcd fine the cooker and lights are not.its ok up to the time i switch on an item that is not protected by the rcd off goes the rcd turning the house off except for the unprotected mcb's no mcb's trip.and putting what could be faulty circuits on the protected side makes it all ok why is this happening ?
