I will start with the most expensive first.
Naturally all equipment connected to them will also be snatched as evidence.
To save us all plenty of time. Just send me all your equipment now.

About 20 years ago an electrician showed me some pictures of an electrical explosion that injured him and totally melted the guts in a Square D 120/240V load center.He had went out on a service call to look at an outage of an outside sign that was mounted on a pole a ways from the building. The maintenance man should him the panel and the tripped single pole 20 amp breaker, that fed the sign. (Sign was 120V)
The first thing the electrician did was to try and reset the breaker. Good thing he stood to the side of the panel looking away from it.
When he pushed the breaker handle to the on position the breaker exploded outward burning his fingers, hand and arm. He was temporarily blinded by the white flash of the explosion. Though he couldn't see the panel immediately after the explosion he could hear the sound of loud arcing inside the panel enclosure.
After he returned from going to the ER, at a local hospital, he went back to asses the damage. He took pictures of what was left of the interior guts of the panel. At the bottom of the panel was a cold dry puddle of copper. The puddle was the remains of the 2 HOT copper bus of the panel.
Further investigation found that who ever installed the main lug only Square D panel (125 amp bus rating) fed it directly from the main 120/240V 3 phase 4 wire 1600 amp panel board. (Against NEC code by the way.)
The 1600 amp main never tripped open. The Square D load center just arced and burned until the 2 Hot legs burned themselves free.

Note: The electrician, as soon as he could after the electrical explosion, called the shop and told them what had just happened. The shop immediately sent another service driver to the business, to safely secure the electrical service.
Just one example of the power of electricity.

I managed a car wash and was good with plumbing, hydraulics, and electricity.
I took off on a Saturday, as I was the best man at my friend's wedding.
We hade a large panel with double doors for all the 440 volt 3-phase. Each circuit, mostly for motor control, had a set of 3 fuses. I kept spare fuses, a continuity tester, and a tube puller in the bottom of the cabinet. You test the fuses by pulling them, or with a voltage tester rated for high voltages. You did that with the power on, but only the maintenance man and I would do it that way, if we didn' want to shut everything off.
Well something failed and the relief manager went to check it out. The cabinet had a lever that would shut the main breaker off when opened. Well he got in there and apparently thought the main switch was still on, so he flipped it, then took the fuse puller and tried pulling the fuses, do able, but not real safe. He either touched the fuse to something or it was just the way he pulled it. It blew up, burning his hand badly, and burning his eyebrows off, with a few more injuries. He also burned up some of the wiring putting us completely down.
He had no business being in there, as he didn't know what he was doing. The crazy thing is that they blamed me. I had given plenty of notice and it wasn't like I was just a guest. My fault for not being there. That was the kind of people I worked for.
That guy screwed up by not checking with a meter to make sure it was dead.He's lucky copper and maybe steel splatters from the arcing did not reach his eyes blinding him for life. Or worse yet lost his life.
Did you watch the video from the Link I provided in my last post?
Fast forward/go to frame #839. The guy racking-in the breaker wasn't so lucky. His mistake cost him his life.

The two inner tynes need to be bent back in order to allow the outer two to properly engage the outlet for max current flow.

Bigger zap!
And solid silver no SS flatware or plated. Lower melting temp.

No please no. I promise I won't do it again.
