Product FAQs
7 answersWhat is the difference between the QO115PCAFI and the QO115CAFI?
The QO115PCAFI features a Plug-on Neutral connection and is designed exclusively for Square D QO Plug-on Neutral load centers. It does not have a pigtail wire. The QO115CAFI is the pigtail version, used in standard QO load centers that lack a Plug-on Neutral bus.
Can I install this QO115PCAFI breaker in a Square D Homeline load center?
No. Square D QO breakers are not interchangeable with Homeline panels. Homeline load centers require HOM series circuit breakers.
Does the QO115PCAFI provide Ground Fault (GFCI) protection?
No, this breaker is strictly a Combination Arc Fault Circuit Interrupter (CAFI), meaning it protects against series and parallel arc faults. If your circuit requires both arc fault and ground fault protection, you will need a Dual Function breaker, such as the QO115PDF.
How can I visually tell if the QO115PCAFI has tripped?
This breaker features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or arc fault, a red indicator flag appears in the breaker window, making it easy to quickly identify the tripped circuit in the panel.
Which breaker do I need if my Square D QO load center is not a Plug-on Neutral panel?
If your QO panel does not support Plug-on Neutral installations, you must use the pigtail version of this 15A arc fault breaker, which is catalog number QO115CAFI.
How do I test the arc fault functionality after installation?
Once installed and energized in the load center, press the white test button located on the front of the breaker. The breaker should trip immediately, verifying that the arc fault detection circuitry is functioning properly.
Are there tools required to identify the type of fault that tripped this breaker?
No special tools are required. The QO115PCAFI is equipped with Time Saver Diagnostics. By using a specific sequence with the breaker handle and the white test button, the breaker can indicate whether it tripped due to an overload, a short circuit, or an arc fault.
