Square D HOM120CAFI AFCI Miniature Circuit Breaker

No. The HOM120CAFI is designed exclusively for Square D Homeline load centers. It will not fit in QO panels or load centers from other manufacturers.

The HOM120CAFI features a factory-installed pigtail neutral wire that connects to the neutral bus bar. The HOM120PCAFI is a Plug-on Neutral breaker that connects to the neutral bar without a pigtail, which requires a compatible Plug-on Neutral Homeline panel.

A Combination Arc Fault Circuit Interrupter provides protection against both parallel arcs, which occur between hot and neutral or ground, and series arcs, which occur along a single broken or damaged conductor. This offers more comprehensive fire protection than older branch or feeder AFCI breakers.

Yes. The HOM120CAFI is the modern combination arc fault replacement for the obsolete HOM120AFI, which only provided branch and feeder arc fault protection.

Yes. This breaker includes Square D Time-Saver Diagnostics. If the breaker trips, you can use this feature to identify whether the fault was caused by an arc fault, a short circuit, or a thermal overload.

The load terminal should be torqued to 35.4 lb-in for 14 AWG to 8 AWG copper or aluminum wire.

The coiled white pigtail wire must be connected directly to the neutral bus bar in your Homeline load center to power the internal arc fault detection circuitry.

No. The HOM120CAFI provides combination arc fault protection but does not include ground fault protection. For both AFCI and GFCI protection in a single breaker, you need a dual function model like the HOM120DF.
