What is happening with these electrics?

By a process of elimination I have narrowed the problem down to two lengths of cable, both run under the hall floor.
Thank you all. I now just have to decide whether the occasional RCD trip is worth taking up the floor boards for.
If an RCD trips it's because stuff is shorting out. That's a fire risk.
No, it is not
It is because there is current getting to earth other than via the RCD,
whicjh is not a fire risk
It could be no more than too many RF filters across the mains, which is
not a fire risk
It could be because there is a neutral/earth short somewhere, which is
not a fire risk
It could be because a heater element is slightly leaky., which is not a
fire risk
In fact RCDs are really there to prevent electric shocks due to improper
earthing or erth leak faults. They are not there to pervenet fire riss

That is the MCBs' job along with appliance and plug fuses.
With respect he said it's mouse cable damage.
Where?
We've no way to know if the shorting or leakage is L-E or N-E.
Yes we have, because LE would trip the MCB and elecrocute the ****ing
mouse. BTDTGTTS
Leakage can often icnrease oevr time, and as carbonisation occurs it
can become a fire starter. An MCB won't do anything until i exceeds it's
rated current by a fair margin. A fire can be started before that
happens. Obviously that situation is a fire risk.
how does 'carbonisation' occur except by a partial short ?
Anyone can invent arbitrary improbable and never seen in the wild
scenarios in orer to avoid losing an argument
