and a highly visible, red indicator easily identifies the tripped breaker. When a QO Visit-Trip circuit breaker trips, the handle snaps to a midpoint position between in. On top of that, all QO circuit breakers are equipped with the exclusive Visit-Trip indicator. It saves money by reducing troubleshooting time, simple to use, accurate and reliable. Time-Saver Diagnostics helps take away the guess work and provides diagnostic assistance by identifying the type of fault that last occurred. Now standard in all Square D brand CAFCI circuit breakers, Time-Saver Diagnostics provide advanced trip indication technology, helping identify the type of fault that has occurred faster. QO 20 Amp Single-Pole Combination Arc Fault Circuit Breaker(QO120CAFIC) The Square D by Schneider Electric QO 20 The Square D by Schneider Electric QO 20 Amp Single-Pole Combination Arc-Fault Circuit Interrupting (CAFCI) Circuit Breaker is for use to help protect your wires from arcing faults and is intended for overload and short-circuits protection of your electrical system. This QO CAFCI breaker is compatible with Square D's QO Plug-On Neutral breaker boxes ONLY. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection. QO circuit breakers have features no other manufacturer can offer. ![]() QO Plug-on Neutral provides several advantages and among them is fewer connections which lead to faster installation and an innovative neutral jaw eliminates pigtails which in turn frees gutter space. Designed for reliability, the QO Plug-on Neutral CAFI Circuit Breaker connects directly to the neutral bar, providing a time and labor-saving installation. Only certain Homeline load center catalog numbers that were designed to accept tandem breakers will allow the tandem to be installed.The Square D by Schneider Electric QO 20 Amp Single-Pole Plug-on Neutral Combination Arc-Fault Circuit Interrupting (CAFCI) Circuit Breaker is for use to help protect your wires from arcing faults and is intended for overload and short-circuits protection of your electrical system. This short notch prevents the HOMT from fully engaging the bus stab and therefore will prevent the deadfront/cover from fully seating over the branch breakers. The rejection feature is a ‘Short Notch’ in the breaker casing, where the breaker plugs onto the bus stab of the load center. The HOMT tandem breaker, example HOMT2020, has a rejection feature built into the breaker casing. NOTE: If the load center is not designed to accept HOMT tandem breakers, then the HOMT's CANNOT be installed in the load center, it would require a newer load center that is designed to accept tandem breakers. Because of the circuit limiting requirement, not all spaces in the older Non Plug-On Neutral load centers would accept tandem breakers. Older style or Non Plug-On Neutral Homeline load centers were designed to meet the UL standard and the NEC Circuit Limiting Requirement(42 circuit rule). These are load center cover part numbers. NOTE: Catalog numbers starting with 'HOMC.' are not load center part numbers.
