Square D HOM120GFI – Frequently Asked Questions

1) Can I use this Homeline GFCI breaker on an air conditioner or heat pump circuit?
Yes. The breaker is HACR rated, which is what lets it be used on heating, air conditioning, and refrigeration equipment branch circuits. It also carries a 10 kA short circuit interrupting rating and is rated for 120 V AC operation.
2) What size wire do the terminals on the Homeline GFCI breaker take?
Screw clamp terminals accept one conductor from AWG 14 through AWG 10, aluminum or copper, torqued to 4.1 N.m. Sizing beyond AWG 10 means a different breaker.
3) Is the Homeline GFCI a Class A device that meets the 6 mA personnel protection level?
Yes. It provides Class A ground fault protection, tripping at 6 mA, which is the personnel-protection level, and it is UL Listed. That is different from equipment ground fault protection at 30 mA.
4) Can I swap a standard Homeline breaker for this GFCI version in an existing panel?
Mechanically, yes: it is the same plug-in Homeline form factor and snaps onto the bus in a Homeline load center or CSED. The wiring is what changes. A GFCI breaker needs the circuit neutral landed on the breaker's neutral terminal and the pigtail run to the panel neutral bar, not the neutral left on the bar as with a standard breaker.
5) Can an ABB ST200M miniature breaker be used in place of a Homeline GFCI breaker?
No. The Square D Homeline GFCI breaker is a plug-in miniature circuit breaker built to snap into Homeline load centers and CSEDs, and it adds Class A 6 mA ground fault protection on a 120 V circuit. The ABB ST200M is a UL1077 miniature circuit breaker, a supplementary-protection device on a DIN rail rather than a plug-in branch breaker for a Homeline panel, and it carries no ground fault function. If the opening is a Homeline load center needing GFCI protection, the Homeline GFCI breaker is the device that fits the bus; the ST200M belongs in DIN-rail control and equipment enclosures.
6) What should I use instead of a Homeline GFCI breaker for a 3-phase feeder or large equipment circuit?
The Homeline GFCI breaker is a 2-pole, 120 V plug-in device sized for residential and light commercial branch circuits. For a 3-pole feeder or main-equipment application, a molded case breaker is the right family: the ABB A2N Series is a 3-pole molded case circuit breaker, and the ABB E150 Series is a 3-pole thermal magnetic circuit breaker. Both are 3-pole molded case designs rather than plug-in miniature breakers, so they mount in their own enclosures or switchboards instead of a Homeline load center, and neither provides the Class A 6 mA personnel ground fault protection the Homeline GFCI breaker does.
7) What amperages does the Square D Homeline GFCI breaker come in?
Two ratings are offered: a 20A version, catalog number HOM120GFI, and a 35A version, HOM235GFI. Both carry Class A ground fault protection at 6 mA.
8) Is a 10 kA interrupting rating enough for my panel?
The Homeline GFCI breaker is rated 10 kA AIC at 120 V AC, which covers typical residential and light commercial service where available fault current is at or below 10 kA. If your engineer's fault study calls for more than 10 kA at that panel, you need a higher-AIC device, and for larger three-phase distribution work that means a molded case breaker such as the ABB A2N Series or the ABB E150 Series thermal magnetic breaker rather than a plug-in Homeline.
9) Is this Homeline GFCI breaker TAA compliant for a government or institutional job?
Yes, it is listed as TAA compliant, along with UL Listed and HACR rated. It is also mercury free, halogen free, and RoHS Europe compliant with exemptions, which covers most institutional procurement checklists.
10) Is the ABB XT4 kit a substitute for a Square D Homeline GFCI breaker?
No, they solve different problems. The ABB XT4 Series item is a 3-pole molded case circuit breaker kit. The Square D Homeline GFCI is a single plug-in miniature breaker with screw clamp terminals that seats on the bus of a Homeline load center and is UL Listed and HACR rated for air conditioning and refrigeration circuits. An XT4 molded case device cannot plug into a Homeline panel, and the Homeline breaker will not serve a 3-pole molded case position.
11) What accessories work with the Homeline GFCI breaker?
It accepts HOMELEC1PA, QO1LO, HOM1PA, and HOM1HT accessories, which cover things like handle padlocking and handle tie needs on the breaker.
12) What ambient temperature is the Homeline GFCI breaker rated for?
Up to 40 degrees C ambient air temperature. In a hot attic or an unventilated outdoor enclosure that runs above 40 C, expect derating and plan the panel location accordingly.
