Product FAQs
6 answersCan I install the QOB115GFI in a standard QO load center?
No. The QOB115GFI features a bolt-on connection designed specifically for Square D NQ and NQOD panelboards. For a standard QO load center, you will need the plug-on equivalent, catalog number QO115GFI.
What is the plug-on equivalent for this bolt-on GFCI breaker?
The plug-on equivalent is the Square D QO115GFI, which is used in standard QO residential and commercial load centers.
What is the ground fault trip threshold for the QOB115GFI?
This breaker provides Class A ground fault protection for personnel and is designed to trip when it detects a ground fault leakage current of 6 mA.
Is there an Equipment Protection Device (EPD) version of this 15A breaker?
Yes. If you need equipment protection with a higher 30 mA trip threshold to prevent nuisance tripping on heat trace or industrial equipment, use the Square D QOB115EPD.
How is the neutral connection made on the QOB115GFI?
This breaker includes a pigtail neutral wire that must be routed and connected directly to the neutral bus bar in your NQ or NQOD panelboard to ensure proper ground fault sensing.
Does this breaker feature a tripped status indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips due to an overload, short circuit, or ground fault, a highly visible red flag appears in the handle window to help you quickly identify the tripped circuit.
