Behold, Wim Ton signalled from keyed 4-1000A filament:

Anyone got any high-current/low-voltage horror stories they'd care to
share?

You should see a 440 RMS working volt 50,000 Joule MOV on a 600 amp
440 line that has received an over voltage spike.

The only thing left are the connecting wires and they are pointed
straight out. They are blinding if you happen to be looking at one
when it blows, or deafening if you are near. They'd put any 12 gauge
shotgun to shame.

These things are about 3 X 4 inches and just shy of an inch thick.

I friend who is a power IC developer told me about FETs being blown up
by the enery stored in the self inductance of the IC bond wire.

That's why FET is known by many to stand for Fire Emitting Transistor ;-)
