Product FAQs
6 answersCan I install the HOM115AFI in a Square D QO load center?
No. The HOM115AFI is exclusively designed for Square D Homeline load centers. QO panels require QO series breakers, which have a different mounting footprint.
Does the HOM115AFI require a plug-on neutral panel?
No. This breaker features a pigtail neutral connection, meaning the coiled white wire connects directly to the panel neutral bus bar. It can be installed in older or standard Homeline load centers that do not have plug-on neutral capabilities.
What is the difference between the HOM115AFI and HOM115CAFI?
The HOM115AFI is a branch/feeder arc fault circuit interrupter. The HOM115CAFI is a combination arc fault circuit interrupter (CAFI) that detects both series and parallel arcing. The HOM115CAFI is the direct modern replacement for the HOM115AFI.
What is the difference between the HOM115AFI and HOM115PCAFI?
The HOM115AFI uses a pigtail neutral wire that connects to the neutral bus. The HOM115PCAFI is a Plug-on Neutral breaker that connects directly to the neutral bar without a pigtail, which requires a compatible Plug-on Neutral Homeline panel.
What type of arc fault protection does the HOM115AFI provide?
The HOM115AFI provides branch/feeder arc fault protection. This older standard is designed to detect parallel arcing faults in the branch circuit wiring, unlike newer combination AFCI breakers that also detect series arcs.
Is the HOM115AFI suitable for HVAC equipment?
Yes. The HOM115AFI is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a breaker with this designation.

- 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.
