The QO235 – Square D 2P35A 120/240V Push In Breaker is a reliable and efficient circuit breaker designed for residential and commercial use. With a 35-amp capacity, it offers robust protection for your electrical systems. Its push-in design eases installation, ensuring a secure connection and optimal performance for all your circuit needs.
No, they are not interchangeable. The QO235 uses Square D's QO plug-in bus design with the signature rejection clip, while Homeline breakers use a different clip and bus tab profile. Installing a Homeline breaker in a QO panel (or vice versa) is unsafe and code non-compliant. Always match the breaker series to your panel series.
The QO235 is an active Square D part. Northern Breaker Group stocks a wide range of QO-series breakers across our Calgary, Edmonton, and Vancouver locations. If you need a replacement quickly, contact us for availability — we specialize in both current and hard-to-find breakers and can often supply same-day or next-day at the counter.
For a 35A circuit under the Canadian Electrical Code (CEC), the typical minimum conductor size is #8 AWG copper (or #6 AWG aluminum) for a 75°C-rated wire. Always verify conductor sizing with a licensed electrician, as conduit fill, ambient temperature, and load type can affect the required wire gauge. The QO235 terminal is rated for this range, but confirm your specific installation requirements with your local authority having jurisdiction (AHJ).
