I've got a better one for you: a certain piece of 11kV switchgear has little M10 steel bolts attaching the cable box cover. If you turn them too quickly with the cover under tension the steel heats up through friction and welds the fucking screw into the thread.

The latest version uses M13 and I think the problem has been mitigated a bit, but I'm sure it can still happen, and there's a metric shit ton of the old stuff out in the wild.

All full of SF6 as well, which is a very cool (I really want to inhale some and sound like Darth Vader) but also really bad greenhouse gas (20x worse than CO2), and with so much out there inevitably some of it leaks (with a 20 year time delay from a leak to the gas reaching the upper atmosphere), but we can't be having switchgear taking up more space and commercial enterprise profits diminishing to cover it so we just continue our global exponential growth in use of the stuff.
