I like that 350 amp one.

The 2000 amp class can also serve as a improptu welder.

Somewhere in my company's engineering drawing database is a medium voltage fast blow squirrel fuse that I drew up after one such critter blew one of our substations. And the wag in charge of drawing numbers liked it south he assigned a number to it and approved it.

One of my guys tested the 2000 A version last year, I would post the picture if I could find it. Told him to disconnect the power supply to send it back for repair. The defective power supply was located in a rack, to make work easier he also removed the unit above which was still operating properly. He just diconnected the protection cover and went at it. Didn't bother to check that the upper unit was connected to a 480V 60A 3 phase circuit. I am surprised he is alive today. Probably because he was standing on some cables (his laziness of not removing the cables might have saves his arse), and he was wearing nitrile gloves, but I doubt those can protect agains 480V.

The 13 mm Craftsman ratcheting wrench suffered some damage but amazingly the ratchet still works! We still use it.

I tested quite a few of the 350 amp models back in the early 70s at Ft. Knox.

I used the vice-grip version of the 2000 amp one once.

I've seen guys use the foil from a cigarette pack to wrap around a blown 3AG fuse.
