I wouldn't have said condensation alone would cause an arc like that. Especially in an LV board.
i thought that at first, when you look at the Mcb those prongs have a plastic cover over them and these were still in place apart from the centre cover had come loose after the fault along with the fact it being the second way down makes it even stranger.I would have maybe said something loose inside the panel, finally moved due to vibration or similar. You'll struggle to melt copper like that without a direct short.
Hi, there was nothing that could of shorted at all, clipped in nice and tight, only one of the covers had come loose and the others were still intact and secure, the busbars on the gear tray were still nice and cleanAs all the burning appears to be down the middle was there anything that could of shorted between the front and the terminals?
looks an expensive repair and once done it might just do it again
there is some rust showing on the cabinet
