thats what main breakers are designed for, changing breakers in a hot panel is just plain dumb...

of course you have to reset clocks etc......

but you have to do that if your home has a power failure
On a square D QO panel you'd have to be pretty stupid to shock
yourself changing a breaker with the panel "live". Like you'd almost
have to TRY.
