  • Plug-In Installation: Designed to plug directly into Homeline load centers for fast, straightforward circuit protection setup.
  • 2-Pole Configuration: Provides double-pole circuit protection for 240V branch circuits.
  • Combination Arc Fault (CAFI) Protection: Guards against dangerous arc faults in addition to equipment overloads and short-circuits.
  • Pigtail Neutral Connection: Simplifies neutral wiring at the load center.
  • 10kA AIR Rating: 10 kA short circuit current rating for dependable interruption performance across every amperage option.
  • 120 V AC Operational Voltage: Rated operational voltage of 120 V AC on all options in this family.

Square D HOM220CAFI – Frequently Asked Questions

1) Will the Square D HOM215CAFI breaker fit any panel, or only Homeline load centers?
Homeline load centers only. The HOM-CAFI is a plug-in miniature breaker built to the Homeline footprint, so it will not seat correctly in a QO panel or another manufacturer's bus. It occupies a 2 in width, 3.13 in height, 2.98 in depth envelope. If your panel is a GE/ABB loadcenter, the ABB THQL or THQB families are the ones designed for that bus instead.
2) What wire sizes can I land on a Homeline 2-pole CAFI breaker?
The terminal takes one AWG 14 through AWG 8 conductor in aluminum or copper, or two AWG 14 through AWG 10 copper conductors in the same clamp. That covers 15A and 20A branch circuits on 14 and 12 AWG copper with room to upsize for voltage drop on a long run.
3) Does this 2-pole arc fault breaker need a neutral pigtail connection at the panel?
Yes, it uses a pigtail neutral. The white lead off the breaker goes to the load center neutral bar, and the circuit neutral lands on the breaker's neutral terminal. That is different from a plug-on neutral design, where the breaker picks up neutral straight off the bus, such as the ABB THQL plug-on neutral ground fault breaker.
4) Which amperage should I order, and what are the part numbers?
Two ratings are offered: 15A as HOM215CAFI and 20A as HOM220CAFI. Match the breaker to the branch circuit conductor, 15A for 14 AWG copper and 20A for 12 AWG copper. Voltage rating, 10kA interrupting capacity, and construction are the same on both.
5) I need ground fault protection, not arc fault. Is the Square D HOM-CAFI breaker the right choice?
No. The Square D Homeline HOM-CAFI is a combination arc fault breaker, which protects against arcing faults plus overload and short circuit. If the requirement is ground fault protection, a GFCI breaker such as the Eaton CH Series Class A GFCI with pigtail or the ABB THQL Q-Line Model 3 self-test GFCI covers that function instead. Use the breaker family that matches the panel brand.
6) What is the closest alternative to the Square D HOM215CAFI if the panel is an ABB or GE-style load center instead of Homeline?
The HOM215CAFI and HOM220CAFI are plug-in breakers built for Square D Homeline load centers, so they cannot be used in an ABB Q-Line panel. For arc fault protection in an ABB panel, the ABB Q-Line THQL11 DFCI is a dual function AFCI/GFCI breaker. Match the breaker line to the panel it is going into rather than the amperage alone.
7) Does any comparable breaker combine both arc fault and ground fault protection in one device?
The Square D Homeline HOM-CAFI provides combination arc fault protection along with overload and short circuit protection. If a single device needs to cover both arc fault and ground fault, the ABB Q-Line THQL11 DFCI is a dual function AFCI/GFCI breaker. The ABB unit is for ABB Q-Line panels, while the HOM-CAFI plugs into Homeline load centers.
8) Can I use this breaker on a 240V circuit if it is rated 120V AC?
The 2-pole configuration provides double-pole protection for 240V branch circuits, while the rated operational voltage stated for the device is 120V AC, which is the line-to-neutral value across each pole. Both poles trip together, so a multiwire branch circuit or a 240V load fed from both legs is protected as one circuit.
9) Is a Homeline CAFI breaker acceptable for an HVAC or refrigeration circuit?
Yes, it is HACR rated, so it can be applied to heating, air conditioning, and refrigeration equipment branch circuits. Pair that with the 2-pole configuration and it suits a 240V condensing unit or similar two-leg load.
10) Is this breaker UL Listed and TAA compliant for a government or institutional job?
Both. The Homeline 2-pole CAFI is UL Listed and TAA compliant, which matters on federally funded work with domestic sourcing language. It is also a halogen free product and is made in Mexico, useful if your submittal package asks for country of origin.
11) How does the neutral connection on the Square D HOM-CAFI compare to plug-on neutral breakers?
The Square D Homeline HOM-CAFI uses a pigtail neutral that lands on the load center neutral bar, as does the Eaton CH Series Class A GFCI breaker. The ABB THQL plug-on neutral ground fault breaker instead picks up its neutral from the panel bus. Confirm which style your load center is built for before ordering.
12) Is the ABB THQB 2-pole GFT breaker a substitute for the Square D HOM220CAFI on a 2-pole circuit?
Both are 2-pole breakers rated 10kA interrupting, but they are not interchangeable in function or panel. The ABB THQB 2-pole is a ground fault breaker for ABB THQB panels; the Square D HOM220CAFI is a combination arc fault breaker that plugs into Homeline load centers. Choose by the protection type the circuit calls for and the panel brand on site.
13) What ambient temperature is a Homeline CAFI breaker rated to operate in?
Rated for 40 C ambient air temperature. In a hot attic or an unventilated outdoor panel enclosure running past that, expect thermal tripping on loads well under the nameplate amperage, so plan placement accordingly.
14) How much space does one of these breakers take in the load center?
Each unit measures 2 in wide, 3.13 in high, and 2.98 in deep, so a 2-pole CAFI consumes two adjacent single-pole spaces on the bus. On a full panel, count your open spaces before converting several circuits to arc fault protection.
