I wonder if the bad connection "arc welded" itself so that it performed so well for so long. I have come across a 40 Amp shower circuit where the busbar just contacted the M.C.B. by spring force as it had not been clamped under the terminal clamp. Remarkably it showed no sign of overheating or damage.
