Square D HOMT2020 20/20A Tandem Miniature Circuit Breaker

The HOMT2020 is designed exclusively for Square D Homeline load centers. Because it is a tandem breaker, the panel must be designed to accept tandem configurations. Check your load center wiring diagram to confirm it allows for tandem or twin breakers in the desired slot.

A tandem breaker provides two independent single-pole circuits within the space of one standard 1-inch breaker slot. This is a practical solution for adding a new circuit to a fully occupied panel without needing to install a subpanel.

The terminals are rated for use with either copper or aluminum wiring ranging from 14 AWG to 8 AWG. Always verify the appropriate conductor size based on the continuous load and local electrical codes.

No. Homeline breakers, including the HOMT2020, have a 1-inch wide format and are not physically compatible with Square D QO panels. QO panels require a 3/4-inch breaker format and a different mounting mechanism.

No. Both part numbers refer to the exact same 20/20A Homeline tandem breaker. The CP suffix simply indicates that the breaker comes in consumer blister packaging, while the standard HOMT2020 ships in standard cardboard packaging for bulk or contractor use.

The HOMT2020 requires only one 1-inch pole space in your Homeline load center, but it provides two independent 20A single-pole circuits. This is why it is often referred to as a space-saver or twin breaker.

No. Tandem breakers like the HOMT2020 are Class CTL and feature a physical rejection mechanism. They can only be installed in specific panel slots approved for tandem breakers. You must consult your load center wiring diagram to identify which bus bar slots will accept them.

No. This is a standard thermal-magnetic breaker, not an AFCI or GFCI breaker. It does not require a neutral pigtail or a plug-on neutral connection. You only connect the ungrounded hot wires to the breaker box lugs.

The HOMT2020 utilizes thermal-magnetic trip technology. The thermal element protects against continuous overloads that can overheat wiring, while the magnetic element provides instantaneous tripping in the event of a severe short circuit. It is not designed to provide Arc Fault (AFCI) or Ground Fault (GFCI) protection.
