Product FAQs
8 answersWhich load centers are compatible with the HOMT220250 quad tandem breaker?
This breaker is designed exclusively for use in Square D Homeline load centers. It cannot be installed in Square D QO panels or panels from other manufacturers. Additionally, it must be installed in panel slots specifically designed to accept tandem breakers.
How are the 20A and 50A circuits configured on this quad breaker?
The HOMT220250 provides two independent 240V circuits. The outer poles are tied together to form a 20A two-pole circuit, and the inner poles form a 50A two-pole circuit.
How many panel spaces does the HOMT220250 require for installation?
This quad tandem breaker occupies two standard 1-inch pole spaces in a Homeline load center, providing four poles of protection in half the typical footprint.
What are the wire gauge requirements for the 20A and 50A terminals?
The box lugs for the 20A outer circuit accept 14 to 8 AWG copper or aluminum wire. The lugs for the 50A inner circuit accept 14 to 6 AWG copper or aluminum wire.
Is the HOMT220250 rated for use with HVAC equipment?
Yes, this breaker is HACR rated, making it compliant for use with heating, air conditioning, and refrigeration motor group combinations.
Do the 240V circuits on this breaker feature common trip functionality?
Yes, both the 20A outer circuit and the 50A inner circuit feature common trip mechanisms. A fault on one leg of either circuit will trip both poles of that specific circuit simultaneously.
What is the difference between the HOMT220250 and HOMT2020250 breakers?
The HOMT220250 has a 2-pole 20A circuit on the outer poles for 240V applications. The HOMT2020250 has two independent 1-pole 20A circuits on the outer poles for 120V branch circuits. Both models share the same 2-pole 50A inner circuit.
What type of trip mechanism does the HOMT220250 use?
It utilizes a fixed thermal-magnetic trip mechanism. The thermal component provides a delayed response to prevent nuisance tripping from temporary overloads, while the magnetic component provides instantaneous tripping during severe short circuits.
