Very intermittent circuit breaker tripping

I been have issues with my electricity tripping at very random times. The strange this is that it usually occurs in the middle of the night or when I am out which means appliances that are on concurrently are at a minimum. On the odd occasion it occurred while I was in the house.
Sometimes it can trip 4-5 times per week and then suddenly it won't trip for a month or more.
I've taken some action to reduce the load on my main RCD protected circuits, but still it is tripping.
I'm not sure what else I can try and I'm not convinced what a qualified electrician can do besides rewiring/replacing the whole unit.
If it needs replacing, then fair enough but how can I check if something is faulty or not?

Thanks in advance

You need to give your location in profile so we can better help but since you said RCD that means your not North American and this is mainly a North American forum so you may only be able to get limited help to differences in wiring practices.

Is this a main breaker tripping or a branch circuit breaker tripping? If a branch circuit is it just one? You mention overload but a RCD may also trip because of moisture. Are any of the outlets (lights or receptacles) exposed to moisture.
