Product FAQs
7 answersWhat is the difference between the QO115PDF and the QO115DF?
The QO115PDF features a Plug-On Neutral connection, which clips directly onto the neutral bar in compatible load centers without requiring a pigtail wire. The QO115DF is the standard pigtail version, which requires you to route and land a coiled neutral wire onto the panel's neutral bus.
Can the QO115PDF be installed in older standard QO load centers?
No. This Plug-On Neutral breaker is designed exclusively for QO Plug-On Neutral load centers. If you are working with an older panel that lacks a Plug-On Neutral busbar, you must use the pigtail version, catalog number QO115DF.
What type of protection does a Dual Function breaker provide?
A Dual Function circuit breaker combines Combination Arc Fault Circuit Interrupter (CAFCI) and Class A 5mA Ground Fault Circuit Interrupter (GFCI) protection into a single device. It is designed to meet NEC requirements for circuits that require both arc fault and ground fault protection.
Is the QO115PAFGF the same breaker as the QO115PDF?
Yes. Both catalog numbers refer to the exact same Square D 15A single-pole Dual Function AFCI/GFCI breaker and are fully interchangeable in the field.
Does the QO115PDF include troubleshooting diagnostics?
Yes. It features Square D Time Saver Diagnostics. This built-in technology allows electricians to troubleshoot a tripped circuit quickly by identifying whether the fault was caused by an arc fault, a ground fault, or a standard short circuit or overload.
How does the Visi-Trip indicator work on this breaker?
The exclusive Visi-Trip indicator provides clear visual confirmation of a tripped circuit. When the QO115PDF trips, a highly visible red flag appears in the indicator window, making it easy to identify the tripped breaker in a fully populated panel.
What does the purple test button indicate on a Square D QO breaker?
The purple Push-To-Test button on the QO115PDF indicates that the device is a Dual Function breaker, providing both arc fault (AFCI) and ground fault (GFCI) protection. This helps quickly differentiate it from standalone AFCI (white button) or GFCI (yellow button) breakers.
