That's gonna be a Federal case. You've got 3 phase wiring coming in that's heavy enough to fry everything in the house. The box has to meet strict codes so it's generally well designed so arranging an "accidental short" on the input side isn't easy, and there's a heavy ground wire to drain off errant voltages.

Anything you do elsewhere will simply blow a fuse or breaker. If you do the old trick of packing a penny under a blown fuse, you'll most likely cause a fire at some circuit box in the attic if you overload the circuit. If it's a breaker box not a fuse box the problem is worse - those things protect themselves too.

You could get some breakers from another box, damage them, and replace good breakers with them (the breakers are often "plug'in" devices). Of course a savey super will just replace the breakers. Damaging the box (short of a lightning strike or truck impact) is hard.

If you damage the meter, that's a plug in unit and property of the electric company. They'll get pretty pissed if the damage looks deliberate and may charge you to plug in a new one.

The most practical method would be to shoot the box with a heavy caliber rifle and blame it on nearby gang activity.
