Product FAQs
5 answersWhich electrical panels are compatible with the QO315GFI?
This breaker is compatible only with Square D QO Load Centers and NQ Panelboards. It will not fit in Homeline panels or load centers from other manufacturers.
How many panel spaces does the QO315GFI occupy?
Because it is a three pole breaker, it requires three full 0.75-inch spaces in your QO load center or NQ panelboard.
What level of ground fault protection does this unit provide?
The QO315GFI provides Class A ground fault protection. It is designed to trip when a ground leakage current of 6mA is detected, which is the standard for personnel protection against electric shock.
What is the purpose of the coiled white wire on this breaker?
That is the pigtail neutral. It must be properly connected to the neutral bus bar in the panelboard to provide a return path and reference point for the ground fault circuit interrupter to function.
Is there a bolt-on version of this 15A GFCI breaker?
Yes. If your NQ or NQOD panelboard requires a bolt-on connection rather than a plug-on format, you will need catalog number QOB315GFI.
