Product FAQs
7 answersCan I install the HOM245GFI in a Square D QO or non-Square D panel?
No. This breaker is specifically designed for Square D Homeline load centers. It is not interchangeable with Square D QO panels or other manufacturers' load centers.
What level of ground fault protection does the HOM245GFI provide?
This breaker provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current of 6 milliamperes (6mA) or higher, protecting personnel from electrical shock.
How is the neutral connected on this GFCI breaker?
The HOM245GFI features a pigtail neutral wire that must be routed and connected directly to the panel's neutral bus bar to ensure proper ground fault detection.
What are common applications for a 45-amp, 2-pole GFCI breaker?
A 45A 2-pole GFCI is typically used for 240V residential applications requiring ground fault protection, such as hot tubs, spas, large RV receptacles, or specific heavy-duty outdoor equipment.
What is the recommended tightening torque for the load terminals on the HOM245GFI?
The screw clamp terminals should be torqued to 40.7 lbf-in (4.6 N-m) to ensure a secure and compliant connection.
What is the difference between HOM245GFI and HOM245GFIC?
Both catalog numbers represent the exact same 45A GFCI breaker. The C at the end of HOM245GFIC simply indicates that the breaker comes in retail clamshell packaging rather than standard bulk packaging.
Is this breaker HACR rated?
Yes, the HOM245GFI is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 45A GFCI circuit.

- 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.
