Product FAQs
8 answersWhat does the "HM" suffix mean on the HOM120HM breaker?
The "HM" designates this as a High Magnetic circuit breaker. It features a higher instantaneous trip threshold to handle applications with high initial inrush currents without nuisance tripping.
Which load centers are compatible with the HOM120HM?
This plug-on breaker is designed exclusively for Square D Homeline load centers. It will not fit in Square D QO panels or load centers from other manufacturers.
Is the HOM120HM rated for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment that requires a 20A, 1-pole circuit.
What wire sizes and materials are accepted by the HOM120HM terminals?
The screw clamp terminal accepts a single 14 to 8 AWG copper or aluminum wire. It is also rated to accept up to two 14 to 10 AWG copper wires.
Can I land two wires on the HOM120HM breaker terminal?
Yes, the terminal is listed to accept two 14 to 10 AWG copper wires. If using aluminum wire or 8 AWG copper, only a single conductor is permitted.
Does the HOM120HM provide arc fault or ground fault protection?
No, this is a standard thermal-magnetic breaker. It provides overload and short-circuit protection but does not include AFCI or GFCI circuitry.
How does a high magnetic breaker differ from a standard HOM120?
While both are 20A breakers, the high magnetic version allows for a larger spike in current for a fraction of a second. This is critical for starting motors or heavy inductive loads that would otherwise trip a standard breaker.
Is the HOM120HM approved for commercial use?
Yes, Homeline miniature circuit breakers are UL listed for both residential and commercial applications when installed in a compatible Homeline load center.
