Product FAQs
8 answersCan I install the QO110 in a Square D Homeline load center?
No. Square D QO and Homeline (HOM) circuit breakers are not interchangeable. The QO110 features a specific plug-on clip design that only fits QO load centers, NQ panelboards, and Speed-D switchboards.
Is there a tandem or twin version of this 10-amp QO breaker?
No. Square D does not manufacture a 10-amp tandem breaker in the QO series. QOT tandem breakers begin at 15-amp ratings, such as the QOT1515.
Does the QO110 feature a tripped circuit indicator?
Yes, this breaker includes Square D Visi-Trip technology. When the breaker trips due to an overcurrent or short circuit, the handle moves to a center position and a highly visible red indicator appears in a window on the breaker case.
How do I reset the QO110 after it has tripped?
To reset a tripped QO breaker, first locate the breaker with the red Visi-Trip indicator showing. Push the handle firmly to the fully OFF position until it clicks, then push it back to the ON position to restore power.
Is the QO110 rated for switching fluorescent lighting loads (SWD)?
No. The SWD (Switching Duty) rating for switching 120VAC fluorescent lighting loads applies to the 15-amp and 20-amp QO breakers. The 10-amp QO110 does not carry the SWD designation.
Is the QO110 HACR rated for HVAC equipment?
Yes, standard QO circuit breakers, including the QO110, are UL Listed as HACR type. This means they are approved for use with heating, air conditioning, and refrigeration equipment that requires HACR-listed overcurrent protection.
What is the difference between the QO110 and the QOB110?
The QO110 is a plug-on circuit breaker designed for QO load centers and NQ plug-on panelboards. The QOB110 has the same electrical specifications but features a bolt-on connection specifically for NQ and NQOD bolt-on panelboards.
Can I use a 10-amp breaker to protect a 14 AWG copper circuit?
Yes. While 14 AWG copper wire is typically protected by a 15-amp breaker in standard residential branch circuits, using a 10-amp breaker provides a lower trip threshold. This is often required for specific dedicated equipment, small motors, or control circuits that specify 10-amp maximum overcurrent protection.
