Square D QO vs Homeline Breakers
QO and Homeline may have similar amp ratings, but they use different product and panel architectures.
QO and Homeline are separate systems
Schneider Electric identifies QO and Homeline as distinct breaker/load-center families and states that they are not interchangeable with each other. Match the exact panel series and breaker family rather than relying on width, handle position or ampere rating.
Third-party classified replacements
Separate third-party classification documentation can exist for specified panels. That does not make QO and Homeline interchangeable with one another, and it does not override the need to verify the exact panel label and classification conditions.
Reference content and catalog data support research. Final breaker or fuse selection must be checked against the exact equipment label, manufacturer instructions, listing or classification conditions, fault-current requirements, coordination, and applicable code.
