Overload Ratings?

Also many years ago, we had the bearings on a 80kw motor fail so catastrophically that the rotor shorted out the windings. It tripped every overload back to and including the main site incomer (north). The emergency generator started up on auto, ran up to speed and connected into the system. Then cut out on overload. It did this twice more on auto before locking out. Started to check the system before connecting to the alternative incomer (south - what else). Found a dead short caused by the distribution panel in the original fault path having all the terminals (3 phase) fused together as one solidified lump of molten metal.

I can imagine a direct lightning strike being somewhat worse!
