RCD nuisance tripping

[Marvo]

Replacing the RCD with RCBO's is treating the symptoms and not the cause of the problem. This is a poor strategy that can be unreliable and can work out expensive. Find the fault, fix the fault, end of problem. If you don't have the equipment or the competence then get someone in to do it.

If there’s a shared neutral between the sockets and lighting, RCBO’s are just going to make matters worse. Or am I being to logical.

The OP has to accept that the fault has to be found and stop faffing about with impractical ideas.
