Why QO has a loyal following among electricians

QO breakers have been around for decades and are known among electricians for a solid, reliable plug-in connection with a slightly heavier-duty feel than Square D's other line. If your panel uses QO breakers, it's often a sign the original installer chose the higher-spec option rather than the cheapest available part.

See our Square D overview page for how QO compares to Square D's other breaker line, Homeline.

Common questions

QO FAQs

Why does my panel use QO instead of Homeline?

QO is Square D's premium line, sometimes chosen by builders or electricians for its reputation, and it's especially common in older, higher-end original installations.

Are QO breakers more expensive than Homeline?

Generally, yes, QO breakers tend to cost more than their Homeline counterparts, reflecting the different design and construction.

Can I upgrade my QO panel to add an EV charger circuit?

In most cases, yes, as long as there's available breaker space and capacity. We assess this during a load calculation before quoting the work.
