It is appropriate to switch off breakers before connecting anything to them. They are designed to be used that way. I've seen breakers that were switched on and off daily for more than 40 years still working.
404.11 Circuit Breakers as Switches. A hand-operable circuit breaker equipped with a lever or handle, or a power-operated circuit breaker capable of being opened by hand in the event of a power failure, shall be permitted to serve as a switch if it has the required number of poles.
Informational Note: See the provisions contained in 240.81 and 240.83.
So according to the NEC, circuit breakers can be used as switches with some provisions.
