I wouldn’t add an upfront rcd at allA main switch....not an rcd main switch. A db with a main switch and sp rcbo's would be compliant. It is not the way i would do it though.
Add a s type rcd main switch and the sp rcbo's are no longer compliant.
Dp rcbos with main switch would be much better although not a requirement
The use of an upfront rcd should be avoided if possible.
