> One thing I learned as amateur EE is to always use just one hand to probe the device under test if there is any high voltage or AC involved.

I remember in some EE course, the prof randomly stopped in the middle of a lecture and said roughly

"Ok now that you all know this theory, I need to remind you that you should not go do your own home electrical work, because you will get ahead of yourself and die from some kind of electric shock"

The implication being:

1. You're trained, but for EE not electrician work

2. You'll think you know what to do, even if you don't it'll cloud your judgement

3. As an EE you will make enough to pay a real electrician to do your electrical work

Needless to say in the real high power EE courses (t lines, grid, etc), this wasn't even mentioned, because it was just implicitly known that all that stuff was in the realm of "Don't physically touch this stuff in the real world ever because it will kill you and it will hurt the whole time you're dying".
