If you were any electrician or close, you would know that lock and tag
out is a must when working on electrical. The exception to the rule is
if you have to do live testing that is required to analyze a problem.
In which case, you're suppose to be warning arc flash clothing.

I was questioning the idea that you needed to kill the entire panel, not just
the circuit in question.

[snip]
You should never assume your breaker to be functioning correctly and
you should never assume that you know which is the correct breaker..

Of course. I always test the circuit before and after killing the breaker, to
verify (a) that the meter works as expected, and (b) that I killed the right
breaker. Anything less is insane.
