Square D HOMT Homeline Tandem Circuit Breaker, 120/240VAC, 10kA AIR

The Square D HOMT Homeline Tandem Circuit Breaker is a miniature circuit breaker (MCB) that plugs directly into Homeline load centers, combining 2 x 1-pole and 1 x 2-pole circuits in one space-saving device. Rated 120/240VAC with a 10kA AIR (short-circuit current) rating, this UL Listed breaker delivers reliable overload and short-circuit protection for residential and commercial panels. This Homeline tandem platform is available across motor full-load-amp (FLA) ratings from 15A to 20A, so installers can match the correct breaker to the connected motor load while relying on the same tandem configuration, voltage rating, and terminal design across the range. Fast plug-in installation and box lug terminations suit new construction, panel upgrades, and circuit additions.

Key Features

  • Tandem Configuration: Combines 2 x 1-pole and 1 x 2-pole circuits in one device, requiring only 2 spaces in a compatible Homeline load center.
  • Voltage Rating: 120/240VAC for standard residential and light commercial circuit protection.
  • Short-Circuit Current Rating: 10kA AIR, protecting connected equipment against overloads and short-circuits.
  • Motor FLA Range: Offered in motor full-load-amp ratings of 15A and 20A to match connected motor loads.
  • Plug-In Design: Snaps directly into Homeline load centers for fast, tool-free installation.
  • Wire Range: Accepts 14 AWG...8 AWG aluminum/copper conductors, tightened to 4.0-4.0 N.m (2.5-6 mm sq).
  • Electrical Connection: Box lug terminals for secure conductor termination.
  • HACR Rated: Suitable for HACR (heating, air conditioning, refrigeration) circuit applications.
  • Ambient Operation: Rated for 40 C ambient air temperature.

Square D HOMT2020220 – Frequently Asked Questions

1) How many panel spaces does the HOMT tandem breaker use, and how many circuits does it give me?
Two spaces. In those two spaces the HOMT gives you 2 x 1-pole circuits plus 1 x 2-pole circuit, so a panel that is full on single-pole positions can pick up a 240V load without a service change. That combination is the whole reason to reach for this breaker instead of two separate devices.
2) What is the difference between the HOMT1515250 and the HOMT2020220?
Both are the same tandem platform at 120/240VAC; the difference is the motor full-load-amp rating. HOMT1515250 is the 15A FLA version and HOMT2020220 is the 20A FLA version. Voltage rating, tandem configuration, and box lug terminals are the same across both, so you pick by the connected motor load.
3) Can I use this Square D tandem breaker on an air conditioner or refrigeration circuit?
Yes, the HOMT carries an HACR application rating, so it is suitable for heating, air conditioning, and refrigeration circuits. Size it to the equipment nameplate: the HOMT comes in 15A and 20A motor FLA ratings, and the unit's maximum breaker size on the data plate governs.
4) Is a 10kA interrupting rating enough for my panel?
The HOMT is rated 10kA AIR at 120/240VAC. For most residential and light commercial services fed from a typical utility transformer that is adequate, but the available fault current at your service determines it. If your plans or utility letter show available fault current above 10kA at the panel, you need a device with a higher interrupting rating, not this one.
5) Can an ABB ST200M miniature breaker be used in place of a Square D HOMT tandem breaker?
No. The Square D HOMT is a plug-in tandem breaker in the Homeline series, combining 2 x 1-pole and 1 x 2-pole circuits in a device rated 120/240VAC that occupies two spaces in a Homeline load center. The ABB ST200M is a miniature circuit breaker with a C-curve trip characteristic listed to UL1077, which is a supplementary protector standard rather than a branch-circuit breaker for a residential or light commercial panel. The two are not interchangeable in a Homeline load center.
6) What wire size will the HOMT breaker terminals take?
The box lug terminals accept 14 AWG through 8 AWG aluminum or copper conductors, torqued to 4.0 N.m. That covers standard 14 and 12 AWG branch wiring and gives headroom for a 10 or 8 AWG homerun on a longer run.
7) Is this breaker UL Listed for use in a commercial building panel?
UL Listed, and rated for residential and light commercial circuit protection at 120/240VAC. It is a miniature plug-in breaker for Homeline load centers, so its use in a commercial building depends on the panel being a Homeline load center rather than a switchboard or molded case application.
8) Is the ABB XT4 breaker kit an alternative to a Square D HOMT Homeline tandem breaker?
No. The ABB MBB33 is a 3-pole molded case circuit breaker kit in the XT4 series, supplied for molded case frame applications. The Square D HOMT is a plug-in tandem miniature breaker that snaps into a Homeline load center and occupies two spaces, rated 120/240VAC. If you are adding circuits to an existing Homeline panel, the HOMT is the device family that fits; the XT4 kit serves molded case equipment instead.
9) What is the difference between the Square D HOMT tandem breaker and an ABB A2A150TT molded case breaker?
They protect at different levels of the system. The Square D HOMT is a plug-in miniature tandem breaker in the Homeline series, rated 120/240VAC, that adds branch circuits inside a Homeline load center. The ABB A2A150TT is a 3-pole molded case circuit breaker in the A2N series, a frame-mounted device used for three-phase feeder and equipment protection rather than for single-phase branch circuits in a plug-on residential panel.
10) Will the HOMT hold up in a hot attic or an unconditioned mechanical room?
Rated for 40 C ambient air temperature. Above that, breaker thermal elements trip earlier than their nameplate, so for panels in consistently hotter spaces plan on derating the circuit load rather than assuming full ampacity.
11) Do I need any tools or extra parts to install the HOMT tandem breaker?
Installation is plug-in: the breaker snaps onto the Homeline bus, no mounting hardware to order. All you need is a screwdriver to land the conductors in the box lug terminals at 4.0 N.m. Nothing else is supplied with the breaker, so panel fillers or handle ties for other positions are separate.
12) Does the Square D HOMT meet green procurement requirements for a sustainability-focused spec?
The HOMT is mercury free and free of toxic heavy metals, and it ships in sustainable packaging using recycled cardboard with no single-use plastic. It is listed as non-serviceable, so it is a replace-on-fail device rather than one you rebuild.
