Product FAQs
7 answersWhich panelboards and load centers accept this GFCI breaker?
This plug-on breaker is designed exclusively for Square D QO load centers and NQ panelboards. It is not compatible with Square D Homeline panels, which use a different bus bar configuration.
How is the pigtail neutral wired on this breaker?
The attached coiled white wire must be connected directly to the panel neutral bus bar. This connection is required to power the internal circuitry that monitors for ground faults.
What level of ground fault protection does this unit provide?
It delivers Class A ground fault protection, designed to trip when a leakage current of 6mA or higher is detected. This meets NEC requirements for personnel protection in wet or damp locations like pools, spas, and outdoor circuits.
Does this breaker include a tripped state indicator?
Yes, it features 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 window to help quickly identify the tripped circuit.
Is the QO260GFI4 interchangeable with the standard QO260GFI?
Yes, the QO260GFI4 and QO260GFI share the exact same physical dimensions, electrical ratings, and plug-on mounting style. The suffix typically denotes packaging variations for retail or bulk distribution.
How often should the ground fault function be tested?
The manufacturer recommends testing the GFCI mechanism monthly. Press the integrated test button on the face of the breaker while it is energized to verify the safety circuitry is functioning correctly.
How much panel space does this 2-pole breaker require?
It requires two standard 3/4-inch spaces in a compatible QO load center or NQ panelboard.
