Power is "fun". I have more experience than I should and won't go into it because it would dox me.
For my personal projects I get a little careless sometimes. Not a danger just "well, I am going to do it live". Getting zapped is not exactly healthy but it sure wakes you up.
If 240 or less, do it live. If bit 2 times shut if off. Big power, call a buddy. I’m so fucking lazy I’ll short the circuit at the plug/switch if it bites me 2x. Then pop the breaker. “That could start a fire”
Sure bro, if the breaker can’t handle a direct short then we got more problems. Yeah it could cause a good spark bead at the plug.
But yeah that’s me too.
