Please bear in mind that if your installation is protected by BS88 HRC fuses, you will need your RCBO's rated at a minimum of 6kA. If your installation is protected by BS1361 HRC fuses, you can get away with 4kA. This is based on the assumption that the Prospective Fault Current for general domestic supplies exceeds 15kA (as it generally does). If the same brand CB's are used throughout the installation, a reduced kA rating of downstream CB's may be permitted if "cascaded" correctly with the Main switch, which must be a CB in this case.
