Product FAQs

5 answers
Which load centers are compatible with the HOM120DF circuit breaker?

This breaker is designed specifically for use in Square D Homeline load centers. Because it utilizes a pigtail neutral, it is compatible with both legacy and modern Homeline panels.

Does the HOM120DF require a plug-on neutral panel for installation?

No. This breaker features a pigtail neutral connection, which means the coiled white wire must be manually terminated at the panel's neutral bus bar. It does not require a specialized plug-on neutral load center.

Can I terminate two wires under the lug of the HOM120DF?

Yes, the clamp terminal is rated to accept two 14 AWG to 10 AWG copper wires. If using aluminum wire or a larger 8 AWG copper wire, only a single conductor is permitted.

What does dual function protection mean on this breaker?

Dual function indicates that the breaker provides both Combination Arc-Fault (CAFCI) and Class A Ground-Fault (GFCI) protection. This meets National Electrical Code (NEC) requirements for circuits in areas like kitchens and laundry rooms where both types of protection are mandated.

What is the difference between the HOM120DF and the HOM120PDF?

The HOM120DF includes a pigtail neutral wire that must be wired to the neutral bus. The HOM120PDF is the plug-on neutral version, which eliminates the pigtail but requires a compatible Square D Homeline plug-on neutral load center.

    It 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.

    Good product, great price!

    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.

    Deceiving

    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.
