In an earlier post you said that the only difference you see when the
offending breaker is off are the garden lights. Now you say that it
it is "different ones on different occasions, a total of four breakers".

Does that mean that you have 4 breakers for the garden lights and that
any (and only) one of them might be the offending one at any given time?
10 lights on 4 different circuits and the problems move from circuit to
circuit?

If so, then that means that only 1 of the 4 circuits is getting wet at
a time, which is really strange. It also means that all 4 circuits have
some type of moisture issue, which is also kind of strange - unless the
fixtures are crappy and/or the person who did the original wiring screwed
up all 4 circuits.

Since garden lights are not working, one of the four must be responsible
for them. I have no clue what the other three breakers are for.

Since you seem to have isolated it to moisture problems in your garden
lights, I would see if you can see where the water is getting in and
seal them up.
We have a lot of that type of thing here in Florida. I have found you
want to open the wiring compartments, get all of the wires centered in
the box is best you can so they are not touching the sides and
pointing up so water tends to drain out of the connections.
