Do people generally power down the whole panel to do a breaker replacement? Seemed unnecessary to me as long as the breaker being replaced is switched off prior to disconnecting the wire...
I hate arc-fault breakers. Haven't ever had one that would pass its rated current even with a pristine run of romex to the outlet. GFCI breakers do OK, though. Prefer standards just because they'll actually pass their rated current.
As for working in the panel, I'm a very bad example. I work in the panel live all the time, even adding circuits and feeds. The only time I tripped the main was when I moved the main from the meter socket on the front porch (which fed a woefully-undersized branch panel that purported to serve the house) to the newly-installed main panel in the cellar. The key is to properly route and bend all 3 wires so that it only takes one hand to insert the wire into the breaker/busbar and then screw it down with one hand. Two hands in the panel is asking for trouble.
That said, don't be stupid like me.
