Product FAQs
6 answersCan I install the HOM115PCAFI in an older Homeline panel that does not have a Plug-on Neutral bar?
No. The HOM115PCAFI is a Plug-on Neutral (PON) breaker and requires a compatible Square D Homeline PON load center. For older panels without a PON neutral bar, you must use the pigtail version, catalog number HOM115CAFI.
What is the difference between the HOM115PCAFI and the HOM115CAFI?
The HOM115PCAFI features a Plug-on Neutral connection that snaps directly onto the neutral bar of compatible Homeline load centers, eliminating the need for a pigtail wire. The HOM115CAFI includes a traditional pigtail wire for connection to the neutral bus in older, non-PON panels.
What does "Combination Arc Fault" mean on the HOM115PCAFI?
A Combination Arc Fault Circuit Interrupter (CAFCI) provides comprehensive protection by detecting both parallel arcs (between hot and neutral or ground) and series arcs (along a single damaged conductor). This meets modern NEC requirements for living areas.
How does the Time-Saver Diagnostics feature work on this breaker?
Time-Saver Diagnostics is a built-in feature that helps electricians quickly identify the cause of a tripped circuit. By following a simple test sequence using the breaker test button, the unit indicates whether the trip was caused by an arc fault or a standard thermal-magnetic event like an overload or short circuit.
Will the HOM115PCAFI fit in a Square D QO load center?
No. Homeline (HOM) breakers have a 1-inch wide format and are only compatible with Square D Homeline load centers. QO panels require QO series breakers, which have a 3/4-inch wide format, such as the QO115PCAFI.
Is the HOM115PCAFI suitable for use with HVAC equipment?
Yes. This breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires motor group combinations.

- CSCharles S.Verified BuyerReviewingSquare D HOM215GFI - 15A GFCI Miniature Circuit BreakerI recommend this productRated 4 out of 5 stars9/25/26It did the job
My pool motor stopped running, and I found a breaker fault causing the problem. I could not find one locally, and SuperBreakers had a reasonable price with free delivery. I called and asked where they were located, as I wanted it ASAP. The New York gentleman I spoke with checked his inventory and said it would go out that afternoon. When it arrived, it was a snap to get my motor running again.

I was having a hard time finding this partifcular breaker at my local big box building materials retailer and found this and another odd size breaker. Much better price here and shipped in a couple of days. Could not be happier. I will think of this company for future projects.

- HMHope M.Verified BuyerReviewingSquare D HOM220 - 20A 2 Pole Miniature Circuit BreakerI do not recommend this productRated 1 out of 5 stars4/1/26Deceiving
I needed a specific breaker that has a large opening for the wiring. The photos were deceiving and showed what looked like the large opening I need for where the wires go. However, I received the breaker and the opening is the exact same and 2 other breakers I purchased from Home Depot and from Menards. Now I spent another $35 on a breaker I can’t even use. Shopping is outrageously priced, and I tried to return and I literally will have to PAY THEM to return this item. I’m very upset.
