The QO120 Square D 1P20A 120V Push In Breaker is designed for reliable performance and easy installation in residential electrical systems. This single pole circuit breaker offers 20 amps of current capacity and provides excellent protection against overloads and short circuits. Perfect for enhancing your electrical panel’s reliability and safety.
While both are Square D 1-pole 20 A breakers, the QO120 is part of the premium QO series and is only compatible with QO loadcentres — it features Square D's signature Visi-Trip indicator that clearly shows when a breaker has tripped. The HOM120 is designed exclusively for Square D Homeline panels. The two series are not interchangeable, so it's important to match the breaker to your specific panel line.
The QO120 remains an active Square D product and is not discontinued. Northern Breaker Group stocks both new and verified reconditioned units, making it straightforward to source even if local supply is limited. Contact our Calgary, Edmonton, or Vancouver counters for current availability.
Yes — the QO120 is well suited for 120 V, 20 A branch circuits commonly required for kitchen appliance outlets and bathroom receptacle circuits under the Canadian Electrical Code (CEC). Always ensure the circuit wiring is rated for 20 A (12 AWG minimum) and that any GFCI or AFCI requirements for the specific location are addressed, either with a GFCI/AFCI receptacle or by upgrading to a QO120DF or similar combination breaker.
