Product FAQs
6 answersCan I install a Homeline HOM120 breaker in a Square D QO load center?
No, Homeline (HOM) and QO series breakers are not interchangeable. The HOM120 is a 1-inch wide plug-on breaker designed exclusively for Homeline load centers, whereas QO breakers feature a 3/4-inch format and a different busbar connection.
Is the HOM120 circuit breaker HACR and SWD rated?
Yes. The HOM120 carries an SWD (Switching Duty) rating, making it suitable for switching 120VAC fluorescent lighting loads. It also carries an HACR rating for use with compatible heating, air conditioning, and refrigeration equipment.
Can I terminate two wires to the HOM120 breaker lug?
Yes, the terminal is listed to accept two 14 to 10 AWG copper conductors. If you are using aluminum wire, the lug only accepts a single 14 to 8 AWG conductor.
What is the difference between the HOM120 and HOM120CP catalog numbers?
The HOM120 and HOM120CP are the exact same circuit breaker. The "CP" suffix simply designates a commercial blister pack or contractor packaging intended for retail distribution.
How much panel space does the HOM120 require?
As a standard format Homeline breaker, the HOM120 occupies a single 1-inch space on the panel bus. It is not a tandem or half-size breaker.
Is the HOM120 an AFCI or GFCI breaker?
No, the HOM120 provides standard thermal-magnetic overcurrent and short-circuit protection only. It does not provide arc-fault (AFCI) or ground-fault (GFCI) protection.

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.

- GBGrant B. D.Verified BuyerReviewingSquare D HOM120 - 20A 1 Pole Miniature Circuit BreakerI recommend this productRated 5 out of 5 stars11/12/25Needed discontinued breakers
Breakers are breakers. Either they work, or they don't , and my purchase was fine. I purchased these because they are discontinued, but were available from SuperBreakers at a reasonable price. So I'm satisfied, but satisfaction criteria were limited to: (1) are the available; (2) are they new and do they work; and (3) are they not overpriced. All criteria were met.
