Do I enjoy to unplug anything previously I flip a breaker? ...


Answers:    You don not have to unplug anything up to that time you turn it on or turn if off. You form have to reset the time on any clocks on the circuit you turn bad if it is left stale for any length of time.
no but you may want to watch what comes on and see which one is cause problems. there may too plentiful connections tied to one breaker.
