Because it is an RCD. (30ma GFCI for you Americans)
Fix your water infiltration problem on the outside circuit.
No. They are regular breakers. GFCI breakers have a test button. Mine don't.
Are you sure your main is not an RCD? Is there a reset button? (The
RCDs I have seen don't have a test button) You say 63a and that
immediately says this is not the US because we do not have 63a
breakers here. I thought most countries with 220v used RCDs.

I have uploaded two photos of the main breaker box. Please see:

Yes. You are right. One has a test button which doesn't work. I pressed
it. The breaker wasn't tripped.
The closer I look at the main breaker box, the more confusion I get. At
first, when I saw four breakers surrounding a main breaker, I assume
they are parallel. But now, when I look at the cable connection, it
seems to me the two Ground FL breakers are in serial, same for the other
two First FL breakers.
I don't know why a 63A breaker is connected to another 63A breaker in
serial.
The ones with 4 wires are RCDs
That's what I was thinking too. The bottom two have a 4th wire marked "N". A neutral going through a breaker would seem to indicate it's an RCD/gfci type breaker. Still don't understand all that's there, ie why there are series breakers, why there are 3 hots, etc. But agree that it's RCD and wet wires, not overload that are causing the trips.
3 phase. It is not unusual on large services out there in 220v land
