I dont know enough to speculate on the cause but it there anything
glaringly wrong here.

118A of MCBs on a 80A RCD, but I doubt all the circuits would be fully
loaded for long, are the righthand 32A MCBs both rings?

Assume the EV charger is on the leftmost MCB?Â* Looks more as though the
terminals onto the live busbar weren't properly tight ...

Just looking at the discolouration, I'd say the the terminal on the RCD
was definitely loose. The others may have been or it may have been heat
transferred along the busbar, from the RCD terminal.

Could the busbar be the wrong side of the terminal in the RCD, or can't you do
that with modern kit?
