Zusammenfassung:	An dual function/combination arc fault interrupter (DF/CAFI) circuit breaker or other circuit interrupting device is equipped to select from multiple load profiles for use with an on-board arc fault detection algorithm. The DF/CAFI breaker is provided with a selector mechanism to switch between the multiple profiles in the different look up tables preloaded in the breaker firmware. The installer may select a particular look up table with a particular branch load profile for arc events upon installation for an anticipated load profile. After installation, the user or installer may switch to a different Look Up Table with different load profile parameters upon noticing an excess of nuisance tripping.
