The last MCB on the left is presumably the one lazily added for the car,
taking the combined maximum current on that leg to over 120A, ignoring
the rating of the previously installed RCD.

My thought too. The highest rated MCB's should be closest to the
incoming power (so closest to the RCD).

I suspect the busbar connected to the RCD was not tight enough too,
perhaps because thats where the heat seems to be ??

That fusebox not made for that overload on that leg, maybe it should
have been installed on the right (full picture please!)
