@jea4 - yeah when I'm opening a panel with 3 phase VAC I step to the side and have had some pretty interesting looks when I've told people to step aside and move way back, and I'll absolutely wait for them to comply.
The PPE I have worn when training for 480 three phase, gave me some idea of how dangerous even that is (high joule rating). ISOLATION. Lock out, tag out.
Anyone doing electrical work on their own home, I would highly recommend purchasing an AC detector pen.

I often use it to quickly troubleshoot motor controls, easily finds faults on three phase monitors, motor starters etc. (and then I break out the Fluke). And if it's right there I'll wave it over the conductors just to be super sure, I've absolutely isolated the correct circuit.
Almost every test in my instrumentation course I did, covered how many milliamps it took to stop a heart.
