Product FAQs
5 answersCan I install the QOB260GFI in a standard QO load center?
No. The QOB260GFI features a bolt-on connection designed specifically for Square D NQ and NQOD panelboards. Standard QO load centers require plug-on breakers.
What is the plug-on equivalent for the QOB260GFI?
The plug-on equivalent is the QO260GFI. It offers the same 60A capacity and Class A ground fault protection but features a plug-on mounting style for standard Square D QO load centers.
What is the ground fault trip sensitivity for the QOB260GFI?
This breaker provides Class A ground fault protection, meaning it is calibrated to trip when it detects a ground fault current of 5 mA. This sensitivity level is specifically designed for personnel protection against electrical shock.
Does the QOB260GFI require a neutral connection for 240V two-wire loads?
Yes. Even when supplying 240V or 208V two-wire loads that do not utilize a load neutral, the breaker's pigtail neutral must still be connected to the panel neutral bar. This connection provides the 120V power necessary to operate the breaker's internal ground fault testing circuitry.
What is the recommended tightening torque for the load terminals?
The manufacturer specifies a tightening torque of 44.3 lb-in for the box lugs. Always verify the exact torque specification printed directly on the breaker label prior to installation.

Great price. Fast delivery. My local electric distributor wanted double for the same breaker, so it was a no brainer to order this one. Ordered another one since with the same great service.
