Here in conduit land we'd simply term the wire in a 1900, anticipating using a length of flex for the finished install (dishwasher / dispoaal, etc).
Some of our guys would "nut 'n' tape", other would simply bend the wire back over itself and tape the end.
It was also very rare that we'd connect to a breaker before the "destination" was connected, whether it was a receptacle or an appliance. If we did, we'd tape or LOTO the breaker in the "OFF" position.
